Abstract:
The ethnic composition of US inventors is undergoing a significant transformation — with deep impacts for the overall agglomeration of US innovation. This study applies an ethnic-name database to individual US patent records to explore these trends with greater detail. The contributions of Chinese and Indian scientists and engineers to US technology formation increase dramatically in the 1990s. At the same time, these ethnic inventors became more spatially concentrated across US cities. The combination of these two factors helps stop and reverse long-term declines in overall inventor agglomeration evident in the 1970s and 1980s. The heightened ethnic agglomeration is particularly evident in industry patents for high-tech sectors, and similar trends are not found in institutions constrained from agglomerating (e.g., universities, government).

Abstract:
We present a model of sequential innovation in which an innovator uses several research inputs to invent a new good. These inputs, in turn, must be invented before they can be used by the final innovator. As a consequence, the degree of patent protection affects the revenues and cost of the innovator, but also determines the incentives to invent the research inputs in the first place. We study the effects of increases in the number of required inputs on innovation activity and optimal patent policy. We find that the probability of introducing the final innovation decreases (increases) as the number of inputs increases when inputs are complements (substitutes). We also find that the optimal strength of patents on research inputs is increasing in the degree of substitution between the inputs, but decreasing in the number of inputs for any degree of substitution.

Abstract:
Researchers studying innovation increasingly use indicators based on patent citations. However, it is well known that not all citations originate from applicants—patent examiners contribute to citations listed in issued patents—and that this could complicate interpretation of findings in this literature. In 2001 the US Patent and Trademark Office (USPTO) began reporting examiner and applicant citations separately. In this paper, we analyze the prior art citations of all patents granted by the USPTO in 2001-2003. We show that examiner citations account for 63 per cent of all citations on the average patent, and that 40 per cent of patents have all citations added by examiners. We use multivariate regression and analysis of variance to identify the determinants of examiner shares. Examiner shares are highest for non-US applicants and in electronics, communications, and computer-related fields. However, most of the variation is explained by firm-specific variables, with the largest patent applicants having high examiner shares. Moreover, a large number of firms are granted patents that contain no applicant prior art. Taken together, our findings suggest that heterogeneity in firm-level patenting practices, in particular by high-volume applicants, has a strong influence on the data. This suggests that analysis of firm-level differences in patenting strategies is an important topic for future research.

Abstract:
The care delivery value chain is a framework that can help conceptualize the organization and structure of care delivery for medical conditions. We apply this framework to HIV/AIDS care in resource-limited settings. Several conclusions arise than can help inform the design of care delivery platforms for HIV/AIDS.

Abstract:
The central role of "platform" products and services in mediating the activities of disaggregated "clusters" or "ecosystems" of firms has been widely recognized. But platforms and the systems in which they are embedded are very diverse. In particular, platforms may exist within firms as product lines, across firms as multi-product systems, and in the form of multi-sided markets. In this paper we argue that there is a fundamental unity in the architecture of platforms. Platform architectures are modularizations of complex systems in which certain components (the platform itself) remain stable, while others (the complements) are encouraged to vary in crosssection or over time. Among the most stable elements in a platform architecture are the modular interfaces that mediate between the platform and its complements. These interfaces are even more stable than the interior core of the platform, thus control over the interfaces amounts to control over the platform and its evolution. We describe three ways of representing platform architectures: network graphs, design structure matrices and layer maps. We conclude by addressing a number of fundamental strategic questions suggested by a unified view of platforms.

Abstract:
A point repeatedly stressed by transaction cost economics is that the more specific the asset, the more likely is vertical integration to be optimal. In spite of the profusion of empirical papers supporting this prediction, recent surveys and casual observation suggest that higher levels of asset specificity need not always lead to vertical integration. The purpose of this paper is to uncover some of the factors driving firms to (sometimes) choose to remain separated, rather than integrate, in the presence of high specificity. Its main economic message is that in a world where outside options matter and investments are multidimensional, high levels of asset specificity can foster nonintegration: a low level of specificity provides the most misdirected incentives when transacting in a market (because the outside option of external trade becomes so tempting), thus making a stronger case for nonintegration when specificity is high.

Abstract:
This paper studies a principal's trade-off between using persuasion versus using interpersonal authority to get the agent to 'do the right thing' from the principal's perspective (when the principal and agent openly disagree on the right course of action). It shows that persuasion and authority are complements at low levels of effectiveness but substitutes at high levels. Furthermore, the principal will rely more on persuasion when agent motivation is more important for the execution of the project, when the agent has strong intrinsic or extrinsic incentives, and, for a wide range of settings, when the principal is more confident about the right course of action.

Abstract:
Financial engineering offers the potential to significantly reduce consumption fluctuations faced by individuals, households, and firms. Yet much of this promise remains unrealized. In this paper, we study the adoption of an innovative rainfall insurance product designed to compensate low-income Indian farmers in case of deficient rainfall during the primary monsoon season. We first document relatively low levels of adoption of this new risk management technology: only 5-10% of households purchase insurance, even though rainfall variability is overwhelmingly cited by households as the most important risk they face. We then conduct a series of randomized field experiments to test theoretical predictions of why adoption may be low. Insurance purchase is sensitive to price, with an estimated extensive price elasticity of demand between -0.66 and -0.88. Credit constraints, identified through the provision of random liquidity shocks, are a key barrier to participation, a result also consistent with household self-reports. Several experiments find an important role for trust in insurance participation. We find mixed evidence that subtle psychological manipulations affect purchase, and no evidence that modest amounts of financial education changes participation decisions. Based on our experimental results, we suggest preliminary lessons for improving the design of household risk management contracts.

Abstract:
This paper documents the short-term and long-term trends in internal conflict in South Asian countries, using multiple data sources. I find that incidents of terrorism have been rising across South Asia over the past decade, and this increase has been concentrated in economically lagging regions in the post-2001 period. This is in contrast to both the historical patterns of conflict, and the evolution of other types of violence. Analyzing the role of economic, geographic and demographic factors, I find that poorer areas have significantly higher levels of conflict intensity. The paper reviews the various approaches taken by governments to deal with conflict, contrasting security-based approaches with political accommodation and economic approaches. Finally, the paper reviews the potential role of regional cooperation in mitigating conflict.

Abstract:
The long-standing argument that focused operations outperform others stands in contrast to theory and evidence supporting a broader scope for organizations. The literature on related diversification at the level of the firm provides some reconciliation of these conflicting observations by suggesting that multi-unit firms with a portfolio of related businesses outperform both single-unit firms and multi-unit firms composed of unrelated businesses. Explanations for this relationship between focus and firm performance have largely centered on economies of scope achieved by sharing common resources, such as advertising or production capacity. We consider whether there are similar benefits to relatedness at an operating unit level and whether such benefits stem from spillovers between operating activities. Using data from the hospital industry, we first examine the relationship between focus and performance in cardiovascular care. Then, distinguishing between direct and complementary spillovers, we examine: (1) the extent to which a hospital's specialization in areas related to cardiovascular care directly impacts performance in cardiovascular care (direct spillovers) and (2) whether the marginal benefit of a hospital's focus in cardiovascular care depends on the degree to which the hospital "co-specializes" in related areas (complementary spillovers). We find evidence of complementarities in specialization between cardiovascular care and related service areas.

Abstract:
We document geographic concentration by both venture capital firms and venture capital-financed companies in three cities - San Francisco, Boston, and New York. We find that firms open new satellite offices based on the success rate of venture capital-backed investments in an area. Geography is also significantly related to outcomes. Venture capital firms based in locales that are venture capital centers outperform, regardless of the stage of the investment. Ironically, this outperformance arises from outsized performance outside of the venture capital firms' office locations, including in peripheral locations. Outperformance of non-local investments suggests that policy makers in regions without local venture capitalists might want to mitigate costs associated with established venture capitalists investing in their geographies rather than encouraging the establishment of new venture capital firms.

Abstract:
A new instrument (the Mutual Inheritance Fund or MIF) is proposed whose purpose is to help people carry their savings forward from the moment they retire into their old age. Like annuities, this instrument requires an up-front payment before people receive any benefits while also protecting people from the risk that they will live a long time. The funds that individuals contribute to a MIF are invested in a mutual fund. The proceeds from the fund's underlying assets are reinvested until the contributor dies or he turns an age specified in advance. If a contributor dies before this pre-specified age, his shares are liquidated and the proceeds are distributed to the other contributors to the MIF. Contributors who are alive at the pre-specified age are also paid the value of their accumulated shares. Like tontines, of which MIF is a variant, this instrument has returns that are more tilted towards old age than annuities. Several advantages of this are discussed, including some that may explain why tontines have proven popular with consumers in the past.

Abstract:
What happens when small iconic socially-oriented businesses are acquired by large corporations? Such mergers create significant opportunities for creating both business value and substantially expanded social value, but also pose unusually difficult challenges because the merging entities are often strikingly different in philosophy and operating styles as well as in scale. We examine three examples—Ben and Jerry's acquisition by Unilever, Stonyfield Farm by Groupe Danone, and Tom's of Maine by Colgate—to ascertain what is distinctive about the merger process and to analyze the elements critical to success. We develop suggestions about how other companies considering similar arrangements might best manage the process of courtship, developing agreements, and executing effectively within the newly merged entities.

Abstract:
Japan's industrial landscape is characterized by hierarchical forms of industry organization, which are increasingly inadequate in modern sectors, where innovation relies on platforms and horizontal ecosystems of firms producing complementary products. Using three case studies - software, animation and mobile telephony -, we illustrate two key sources of inefficiencies that this mismatch can create. First, hierarchical industry organizations can "lock out" certain types of innovation indefinitely by perpetuating established business practices. Second, even when the vertical hierarchies produce highly innovative sectors in the domestic market, the exclusively domestic orientation of the "hierarchical industry leaders" can entail large missed opportunities for other members of the ecosystem, who are unable to fully exploit their potential in global markets.

We argue that Japan has to adopt several key legislative measures in order to address these inefficiencies and capitalize on its innovation: strengthening antitrust and intellectual property rights enforcement; improving the legal infrastructure (e.g. producing more business law attorneys); lowering barriers to entry for foreign investment and facilitating the development of the venture capital sector.

Abstract:
We find that missing the quarterly analyst consensus earnings forecast is associated with career penalties in the form of a reduced bonus, smaller equity grants, and a greater chance of forced dismissal for both CEOs and CFOs during the period 1993-2004. These results are obtained after controlling for several proxies for earnings and stock return performance suggesting that boards appear to penalize managers for failing to meet analysts' quarterly earnings forecasts per se. Career penalties for failing to meet the analyst consensus estimate are no different for firms where forecasting earnings is harder. Moreover, such penalties have increased in the post-SOX period. Our evidence suggests that incentives of the CEO and CFO to meeting analysts' consensus forecast might be driven at least partly by career concerns.

Abstract:
This is a descriptive study of the structure of communications in a modern organization. We analyze a dataset with millions of electronic mail messages, calendar meetings and teleconferences for many thousands of employees of a single, multidivisional firm during a three-month period in calendar 2006. The basic question we explore asks, what is the role of observable (to us) boundaries between individuals in structuring communications inside the firm? We measure three general types of boundaries: organizational boundaries (strategic business unit and function memberships), spatial boundaries (office locations and inter-office distances), and social categories (gender, tenure within the firm). In dyad-level models of the probability that pairs of individuals communicate, we find very large effects of formal organization structure and spatial collocation on the rate of communication. Homophily effects based on sociodemographic categories are much weaker. In individual-level regressions of engagement in category-spanning communication patterns, we find that women, mid- to high-level executives, and members of the executive management, sales and marketing functions are most likely to participate in cross-group communications. In effect, these individuals bridge the lacunae between distant groups in the company's social structure.

Abstract:
In Cournot's model of complements, the producers of A and B are both monopolists. This paper extends Cournot's model to allow for competition between complements on one side of the market. Consider two complements, A and B, where the A + B bundle is valuable only when purchased together. Good A is supplied by a monopolist (e.g., Microsoft) and there is competition in the B goods from vertically differentiated suppliers (e.g., Intel and AMD). In this simple game, there may not be a pure-strategy equilibria. In the standard case where marginal costs are weakly positive, there is no pure strategy where the lower quality B firm obtains positive market share. We also consider the case where A has negative marginal costs, as would arise when A can expect to make upgrade sales to an installed base. When profits from the installed base are sufficiently large, a pure strategy equilibrium exists with two B firms active in the market. Although there is competition in the complement market, the monopoly Firm A may earn lower profits in this environment. Consequently, A may prefer to accept lower future profits in order to interact with a monopolist complement in B.

Abstract:
We consider one-to-one matching markets in which agents can either be matched as pairs or remain single. In these so-called roommate markets agents are consumers and resources at the same time. We investigate two new properties that capture the effect a newcomer has on incumbent agents. Competition sensitivity focuses on the newcomer as additional consumer and requires that some incumbents will suffer if competition is caused by a newcomer. Resource sensitivity focuses on the newcomer as additional resource and requires that this is beneficial for some incumbents. For solvable roommate markets, we provide the first characterizations of the core using either competition or resource sensitivity. On the domain of all roommate markets, we obtain two associated impossibility results.

Abstract:
       This paper analyzes changes in concentration levels in the U.S. Advertising and Marketing Services (A&MS) industry using publicly released data that have been largely ignored in past discussions of the industrial organization of this industry, namely those available from the U.S. Census Bureau's quinquennial Economic Census and the Service Annual Survey. We define the A&MS industry in terms of nine sectors, each of which is represented by a separate 5 digit NAICS category. In so doing, we have sought to redress some of the measurement problems surrounding estimates found in the existing literature. Our main findings are threefold.

       First, in the case of the core and largest sector, Advertising Agencies, firm level concentration as measured by Herfindahl-Hirschman Index (HHI) increased slightly but remained relatively low from 1977 to 2002. All of the HHI estimates readily satisfied the standard widely used to characterize an industry as "unconcentrated." We find mixed support for the hypotheses that the ranks of mid-sized agencies were depleted by ongoing waves of mergers and acquisitions and resulted in a polarized size structure. The size distributions of agency revenue have become more polarized in the sense that over time they appear more skewed, more dispersed, and exhibit greater inequality. The share of total receipts realized by small agencies fell while that of large agencies rose. However, the position of mid-sized agencies appears to have changed little over the period 1977- 2002, as measured by the shares of agencies and receipts they represent.

       Second, concentration levels in 1997 and 2002 varied across the nine sectors comprising the A&MS industry, but all were within the range generally considered as indicative of a competitive industry.

       Third, we developed concentration ratios at the level of holding companies (HC's) and find that the four largest HC's captured between a fifth and a quarter of total revenue from the A&MS industry, a share that remained quite stable over the period, 2002-2006. These estimates are lower by an order of magnitude than estimates often cited in the trade press. Reasons for the discrepancy are discussed.

Abstract:
We examine the causes and consequences of European real estate firms' decisions to provide investment property fair values prior to the required disclosure of this information under International Financial Reporting Standards (IFRS). We find evidence that investor demand for fair value information—reflected in more dispersed ownership—and a firm's commitment to transparency increase the likelihood of providing fair values prior to their required provision under International Accounting Standard 40 - Investment Property. We also find that firms not providing these fair values face higher information asymmetry. However, we fail to find that the relatively higher information asymmetry was reduced following mandatory adoption of IFRS. Rather, we find that differences in information asymmetry largely remain. Taken together, this evidence suggests that common adoption of fair value accounting due to the mandatory adoption of IFRS does not necessarily level the informational playing field.

Abstract:
One-sided assignment problems combine important features of two well-known matching models. First, as in roommate problems, any two agents can be matched and second, as in two-sided assignment problems, the payoffs of a matching can be divided between the agents. We take a similar approach to one-sided assignment problems as Sasaki (1995) for two-sided assignment problems and we analyze various desirable properties of solutions including consistency and weak pairwise-monotonicity. We show that for the class of solvable one-sided assignment problems (i.e., the subset of one-sided assignment problems with a non-empty core), if a subsolution of the core satisfies [indifference with respect to dummy agents, continuity, and consistency] or [Pareto indifference and consistency], then it coincides with the core (Theorems 1 and 2). However, we also prove that on the class of all one-sided assignment problems (solvable or not), no solution satisfies consistency and coincides with the core whenever the core is non-empty (Theorem 3). Finally, we comment on the difficulty in obtaining further positive results for the class of solvable one-sided assignment problems in line with Sasaki's (1995) characterizations of the core for two-sided assignment problems.

Abstract:
While effects of public policy are one of the foundations of organizational theory, less explored is how these effects may depend on other external environmental factors. We focus on how policy is a necessary, but not sufficient, condition to understand the growth of banking in the U.S. states, 1896-1978. Three characteristics of banks—simultaneous production and distribution, pooled intra-organizational coordination, and agency relationships—result in a trade-off between centralized and dispersed growth strategies. Which strategy prevails depends on how policy enabling branching interacts with technological, economic, and cultural environments. Our findings contribute to understanding the contingent effects of policy on organizations and the rise of large corporations in the twentieth century.

Abstract:
What happens when people try to "dodge" a question they would rather not answer by answering a different question? Two experiments demonstrated conversational blindness—listeners' surprising failure to notice such dodges—and explored the interpersonal consequences of this phenomenon. Listeners viewed successful question-dodgers as positively as speakers who actually answered the question they are asked, but were not blind to all efforts to dodge: They both noticed—and punished—particularly egregious attempts (Study 1). More troublingly, listeners preferred speakers who answered the wrong question well over those who answered the right question poorly (Study 2).

Abstract:
When investors overvalue a particular firm characteristic, corporations endowed with that characteristic can absorb some of the demand by issuing equity. We use time-series variation in differences between the attributes of stock issuers and repurchasers to shed light on characteristic-related mispricing. During years when issuing firms are large relative to repurchasing firms, for example, we show that large firms subsequently underperform. This holds true even when we restrict attention to the returns of firms that do not issue at all, suggesting that issuance is partly an attempt to cater to broad time-varying patterns in characteristics mispricing. Our approach helps forecast returns to portfolios based on book-to-market (HML), size (SMB), price, distress, payout policy, profitability, and industry. Our results are consistent with the view that firms play an important role as arbitrageurs in the stock market.

Abstract:
We test for evidence of corporate misgovernance at the World Bank. Most major decisions at the World Bank are made by its Board of Executive Directors. However, in any given year the majority of the Bank's member countries do not get a chance to serve on this powerful body. In this paper, we empirically investigate whether board membership leads to higher funding from the World Bank's two main development financing institutions, the International Bank for Reconstruction and Development (IBRD) and the International Development Association (IDA). We find that developing countries serving on the Board of Executive Directors can expect an approximate doubling of funding from the IBRD. In absolute terms, countries serving on the board are rewarded with an average $60 million "bonus" in IBRD loans. This is more likely driven by soft forces like boardroom culture rather than by the power of the vote itself. We find no significant effect in IDA funding.

Abstract:
    Ehlers and Klaus (2003) study so-called house allocation problems and claim to characterize all rules satisfying efficiency, independence of irrelevant objects, and resource-monotonicity on two preference domains (Ehlers and Klaus, 2003, Theorem 1). They explicitly prove Theorem 1 for preference domain R₀ which requires that the null object is always the worst object and mention that the corresponding proofs for the larger domain R of unrestricted preferences "are completely analogous."
    Quesada (2009) in a recent working paper claims to have found a counterexample that shows that Theorem 1 is not correct on the unrestricted domain R. In Lemma 1, we prove that Quesada's (2009) example in not a counterexample to Ehlers and Klaus (2003, Theorem 1). However, in Example 1 and Lemma 2, we demonstrate how to adjust Quesada's (2009) original idea to indeed establish a counterexample to Ehlers and Klaus (2003, Theorem 1) on the general domain R.
    Quesada (2009) also proposes a way of correcting the result on the general domain R by strengthening independence of irrelevant objects in two ways: in addition to requiring that the chosen allocation should depend only on preferences over the set of available objects (which always includes the null object), he adds two situations in which the allocation should also be invariant when preferences over the null object change. We here demonstrate that it is sufficient to require only one of Quesada's (2009) additional independence requirements to reestablish the result of Theorem 1 on the general domain R.
    Finally, while Quesada (2009) essentially replicates the original proofs of Ehlers and Klaus (2003) using his stronger independence condition, here we offer a short proof that uses the established result of Theorem 1 for the restricted domain R₀.

Abstract:
We examine three reforms to property rights introduced by the United States in the Philippines in the early 20th century: the redistribution of large estates to their tenants, the creation of a system of secure land titles, and a homestead program to encourage cultivation of public lands. During the first phase of American occupation (1898-1918), we find that the implementation of these reforms was very slow. As a consequence, tenure insecurity increased over this period, and the distribution of farm sizes remained extremely unequal. We identify two primary causes for the slow progress of reform. The first was the high cost of implementing these programs, together with political constraints which prevented the government from subsidizing land reforms to a greater degree. The second was the reluctance of the government to evict delinquent or informal cultivators, especially on public lands, which reduced the costs of tenure insecurity.

Abstract:
We develop a model of online advertising in which each advertiser chooses from multiple advertising measurement metrics - paying either for each click on its ads (CPC), or for each purchase that follows an ad-click (CPA). Our analysis extends classic auction results by allowing players to make bids using two different pricing schemes, while the driving information for bidders' endogenous selection - the conversion rate - is hidden from the seller. We show that the advertisers with the most productive sites prefer to pay CPC, while advertisers with lower quality sites prefer to pay CPA - a result that may be viewed as counterintuitive since low quality sites cannot proudly tout their conversion rates. This result holds even if an ad platform's assessment of site quality is correct in expectation. We also show that by offering both CPC and CPA, an ad platform can weakly increase its revenues compared to offering either alternative alone.

Abstract:
The past fifteen years has been a period of rapid growth in the practice of multichannel retailing, mirroring the rise of the Internet as a nearly ubiquitous tool that firms use to interact with customers. More than 80 percent of a broad cross-section of U.S. retailers now report that they sell merchandise through multiple channels. This practice seems to be on the cusp of a new era in which firms start demanding even more from their investments, with particular emphasis being given to financial performance in light of the current economic crisis. These circumstances present a great opportunity both to firms that are looking to gain a competitive advantage through multichannel retailing and to researchers who are interested in helping them make more informed decisions. This article provides a broad discussion of these issues, synthesizes current knowledge, and suggests directions for future research.

Abstract:
Western businesses negotiating with Chinese firms face many challenges, from initiating and smoothing communication to establishing long-lasting relationships and mutual trust, and from bargaining and drafting agreements to securing their implementation. Chinese negotiators can be at once warm hosts and friends and tough bargainers. Unique Chinese cultural elements such as complicated local etiquette, obscured decision-making processes, and heavy reliance on interpersonal relationships instead of legal instruments all add to the complexities of Sino-foreign business negotiations, and can make the process tiresome and protracted. Besides talking past each other, Chinese and western negotiators often harbor mutually unfavorable perceptions. Many westerners find Chinese negotiators to be inefficient, indirect, and even dishonest; Chinese negotiators frequently perceive their western counterparts to be aggressive, impersonal, and insincere. The way to decipher the Chinese negotiating style and bring about mutually beneficial results is to better understand the key elements of Chinese culture to which Chinese negotiators attune their business mentality and manners.

Abstract:
This paper describes recent changes in the relationship between firms and nation states. Firms are typically linked to the nation in which they began and are considered to have fixed national identities. While firms have reallocated various activities around the world in response to value creation opportunities, they have largely retained their national identities and their headquarter activities remained bundled in their home countries. This characterization is increasingly tenuous. Firms are redefining their homes by unbundling their headquarters functions and reallocating them opportunistically across nations. A firm's legal home, its financial home and its homes for managerial talent no longer need to be colocated and, consequently, the idea of firms as national actors rooted in their home countries is rapidly becoming outdated. The implications for policy makers and researchers are outlined.

Abstract:
The inability of established firms to make necessary and obvious changes has been a topic of repeated scholarly inquiry. Compared to new entrants, large firms often encounter difficulties in formulating and committing changes due to the complexity in firms' activities. Beyond cognitive limitations, perhaps the most intriguing type of failure is when managers fully understand the nature of the required change, and the company has already developed the relevant capabilities, but the formation of a new set of core activities is still inhibited. Taking a micro-perspective, the paper argues that there are situations where direct top-down interventions are necessary. Termed as 'deep dives', they are interventions targeting implementation of radical routines and resource configuration. Structural arrangements, pre-set change routines, and existing decisional priorities are insufficient to fashion relevant capabilities into new core activities. Ad-hoc problem solving is the key. The paper concludes with a case study, which illustrates how deep dives guide the formation of a set of new core activities in the variation-selection-retention process.

Abstract:
We use a unique database of every SSRN paper download over the course of seven years, along with detailed resume data on a random sample of SSRN authors, to examine the role of demographic factors, career concerns, and social comparisons on the commission of a particular type of gaming: the self-downloading of an author's own SSRN working paper solely to inflate the paper's reported download count. We find significant evidence that authors are more likely to inflate their papers' download counts when a higher count greatly improves the visibility of a paper on the SSRN network. We also find limited evidence of gaming due to demographic factors and career concerns, and strong evidence of gaming driven by social comparisons with various peer groups. These results indicate the importance of including psychological factors in the study of deceptive behavior.

Abstract:
When powerful people cause harm, they often do so indirectly through other people. Are harmful actions carried out through others evaluated less negatively than harmful actions carried out directly? Four experiments examine the moral psychology of indirect agency. Experiments 1A, 1B, and 1C reveal effects of indirect agency under conditions favoring intuitive judgment, but not reflective judgment, using a joint/separate evaluation paradigm. Experiment 2A demonstrates that effects of indirect agency cannot be fully explained by perceived lack of foreknowledge or control on the part of the primary agent. Experiment 2B indicates that reflective moral judgment is sensitive to indirect agency, but only to the extent that indirectness signals reduced foreknowledge and/or control. Experiment 3 indicates that effects of indirect agency result from a failure to automatically consider the potentially dubious motives of agents who cause harm indirectly. Experiment 4 demonstrates an effect of indirect agency on purchase intentions.

Abstract:
People routinely engage in dishonest acts without feeling guilty about their behavior. When and why does this occur? Across four studies, people justified their dishonest deeds through moral disengagement and exhibited motivated forgetting of information that might otherwise limit their dishonesty. Using hypothetical scenarios (Studies 1 and 2) and real tasks involving the opportunity to cheat (Studies 3 and 4), we find that dishonest behavior increased moral disengagement and motivated forgetting of moral rules. Such changes did not occur in the case of honest behavior or consideration of the behavior of others. In addition, increasing moral saliency by having participants read or sign an honor code significantly reduced or eliminated unethical behavior. While dishonest behavior motivated moral leniency and led to strategic forgetting of moral rules, honest behavior motivated moral stringency and diligent recollection of moral rules.

Social networks, such as Facebook and Myspace have witnessed a rapid growth in their membership. Some of these businesses have tried an advertising-based model with very limited success. However, these businesses have not fully explored the power of their members to influence each other's behavior. This potential viral or social effect can have significant impact on the success of these companies as well as provide a unique new marketing opportunity for traditional companies.

However, this potential is predicated on the assumption that friends influence user's behavior. In this study we empirically examine this issue. Specifically we address three questions - do friends influence purchases of users in an online social network; which users are more influenced by this social pressure; and can we quantify this social influence in terms of increase in sales and revenue.

To address these questions we use data from Cyworld, an online social networking site in Korea. Cyworld users create mini-homepages to interact with their friends. These mini-homepages, which become a way of self-expression for members, are decorated with items (e.g., wallpaper, music), many of which are sold by Cyworld. Using 10 weeks of purchase and non-purchase data from 208 users, we build an individual level model of choice (buy-no buy) and quantity (how much money to spend). We estimate this model using Bayesian approach and MCMC method.

Our results show that there are three distinct groups of users with very different behavior. The low-status group (48% of users) are not well connected, show limited interaction with other members and are unaffected by social pressure. The middle-status group (40% users) is moderately connected, show reasonable non-purchase activity on the site and have a strong and positive effect due to friends' purchases. In other words, this group exhibits "keeping up with the Joneses" behavior. On average, their revenue increases by 5% due to this social influence. The high-status group (12% users) is well connected and very active on the site, and shows a significant negative effect due to friends' purchases. In other words, this group differentiates itself from others by lowering their purchase and strongly pursuing non-purchase related activities. This social influence leads to almost 14% drop in the revenue of this group. We discuss the theoretical and managerial implications of our results.

Abstract:
Using rainfall, public relief, and election data from India, we examine how governments respond to adverse shocks and how voters react to these responses. The data show that voters punish the incumbent party for weather events beyond its control. However, we find evidence that fewer voters punish the ruling party when the party responds vigorously to the crisis. Moreover, severe crises are associated with increased voter sensitivity to disaster assistance. These results are consistent with models of government accountability, and provide an explanation for Amartya Sen's claim that democratic governments respond better to salient emergencies than to less conspicuous ones. Even so, the results suggest that even the most responsive government will fare worse in the subsequent election than had there been no disaster.

Abstract:
We compare the quality of accounting numbers produced by two types of public firms - those with publicly-traded equity and those with privately-held equity that are nonetheless considered public by virtue of having publicly-traded debt. We develop and test two hypotheses. The "demand" hypothesis holds that earnings of public equity firms are of higher quality than earnings of private equity firms due to stronger demand by shareholders and creditors for quality reporting. In contrast, the "opportunistic behavior" hypothesis posits that public equity firms, because their managers have a greater incentive to manage earnings, have lower earnings quality than their private equity peers. The results indicate that, consistent with the "opportunistic behavior" hypothesis, private equity firms have higher quality accruals and a lower propensity to manage income than public equity firms. We further find that public equity firms report more conservatively, in line with their greater litigation risk and agency costs.
Keywords: accruals, conservatism, earnings management, earnings quality, private and public firms.

Abstract:
Battered by contracting markets and frozen credit, many businesses today are fighting for survival. Indeed, the current global financial crisis provides a mandate for restructuring. But survival is not the end goal. In fact, cost cutting and restructuring are simply the first steps in repositioning and leading a company and industry through the crisis and in defining how business will be conducted in the future. This paper describes how IBM managed to, not just survive the crisis it faced in the early 1990s, but to reposition the company to lead the industry. The powerful lesson from the IBM story is that innovation is not a side business to running the real business. Innovation is the business. Breakthrough innovations that change people's lives and the very structure and power dynamics of industries can't be managed as "silos," tucked away in corporate, university, or government research labs, in incubators, or within venture capital funded entrepreneurial start-ups. Access to the marketplace is needed to help speed commercialization and adoption. Emerging opportunities must be nurtured and the transition to high growth must be managed. Once breakthrough innovations catch hold, growth must be funded and managed to exploit the full value of the opportunity. And finally, incremental innovations must ensure that businesses that have passed through the high growth stage can continue to deliver the resources, capabilities, and platforms needed to fuel the emerging opportunities of the future. This business lifecycle view of innovation requires new leadership and organizational models and new approaches to managing risk and uncertainty.

Abstract:
This study explores how firms' ownership structures affect their earnings quality and long-term performance. Focusing on a unique sample of private firms for which there is financial data available in the years before and after their initial public offering (IPO), I differentiate between those that have private equity sponsorship (PE-backed firms) and those that do not (non-PE-backed firms). The findings indicate that PE-backed firms generally have higher earnings quality than those that do not have PE sponsorship, engage less in earnings management, and report more conservatively both before and after the IPO. Further, PE-backed firms that are majority-owned by PE sponsors exhibit superior long-term stock price performance after they go public. These results stem from the professional ownership, tighter monitoring, and reputational considerations exhibited by PE sponsors.

Abstract:
This paper surveys recent empirical studies on the economic impacts of immigration. Particular emphasis is given to the experiences of Northern Europe and Scandinavia. The survey first examines the magnitude of immigration as an economic phenomenon in various host countries. The second part deals with the assimilation of immigrant workers in host-country labor markets and the use of social benefits by immigrants. The survey then considers the effect of immigration on the labor market outcomes of natives. The paper concludes with studies of immigration's impact for the public sector of host countries.

Abstract:
Determining staffing levels is an important decision in retail operations. While the costs of increasing labor are obvious and easy to measure, the benefits are often indirect and not immediately felt. One benefit of increased labor is improved quality. The objective of this paper is to examine the effect of labor on profitability through its impact on quality. Since employees at retail stores perform both production-related activities and customer-service activities, I examine both conformance quality and service quality. Using longitudinal data from stores of a large retailer, I find that increasing the amount of labor at a store is associated with an increase in profitability through its impact on conformance quality but not its impact on service quality. While increasing labor is associated with an increase in service quality, in this setting there is no significant relationship between service quality and profitability. My findings highlight the importance of attending to process discipline in certain service settings. They also show that too much corporate emphasis on payroll management may motivate managers to operate with insufficient labor levels, which, in turn, degrades profitability.

Abstract:
We examine the accrual choices of outsourcing firms with links to US congressional candidates during the 2004 elections, when corporate outsourcing was a major campaign issue. We find that politically-connected firms with more extensive outsourcing activities have more income-decreasing discretionary accruals. Further, relative to adjacent periods, the evidence is concentrated in the two calendar quarters immediately preceding the 2004 election, consistent with heightened incentives for firms to manage earnings during the election season. The incentives can be attributed to donor firms' concerns about the potentially negative consequences of scrutiny over outsourcing for themselves and for their affiliated candidates.

Abstract:
Cultural differences can affect negotiations in many ways, from influencing the basic motivations and perceptions of the players to guiding the surface aspects, such as etiquette, protocol, and process, of business interactions. Navigating the challenges of these surface behavioral issues is useful to plumb some of the deeper cultural factors and differences in governance and decision-making of cross-border business negotiation. As suggested by an iceberg analogy, though etiquette, protocol, and deportment comprise the visible tip, they might be linked to more deeply rooted, less obvious forces that are fully capable of sinking the ship. This working paper, through a questionnaire format-intended as an instrument to collect data from a range of people with varying China-related negotiating experience--presents a series of situations of a typical Sino-foreign business negotiation to address both the surface and the root cultural factors. This questionnaire will serve not only to evaluate subjects' appreciation for Chinese culture as it bears on negotiation, but also to better understanding of the process aspects of cross-border negotiation in general.

Abstract:
SFAS 142 requires managers to estimate reporting unit values to determine goodwill write-offs. Those estimates often use unverifiable discounted-future-cash-flows providing managers with more discretion than historically afforded in financial reporting. Ex post, managers can claim their unit value estimates were not realized due to factors outside their control, claims that are difficult to objectively falsify. In promulgating SFAS 142, standard setters assume managers, on average, use unverifiable discretion to convey private information on future cash flows; in contrast, agency theory predicts managers, on average, use unverifiable discretion opportunistically. We test these alternative hypotheses using a sample of firms with market indications of goodwill impairment. Our evidence, while consistent with agency theory, does not confirm the private information hypothesis.

Abstract:
Manufacturers are increasingly being required to adhere to product take-back regulations that require them to manage their products at the end of life. Such regulations seek to internalize products' entire life cycle costs into market prices, with the ultimate objective of reducing their environmental burden. This article provides a framework to evaluate the potential for take-back regulations to actually lead to reduced environmental impacts and to stimulate product design changes. It describes trade-offs associated with several major policy decisions, including whether to hold firms physically or financially responsible for the recovery of their products, when to impose recycling fees, whether to include disposal and hazardous substance bans, and whether to mandate product design features to foster reuse and recycling of components and materials. The framework also addresses policy elements that can significantly affect the cost efficiency and occupational safety hazards of end-of-life product recovery operations. The evaluation framework is illustrated with examples drawn from take-back regulations promulgated in Europe, Japan, and the United States governing waste electrical and electronic equipment (WEEE).

Abstract:
For the classical marriage model (introduced in Gale and Shapley, 1962) efficiency and envy-freeness are not always compatible, i.e., fair matchings do not always exist. However, for many allocation of indivisible goods models (see Velez, 2008, and references therein), fairness can be restored if a sufficiently large amount of money is available for distribution/compensation as well. Interpreting the agents as the objects to be allocated, one might try to restore fairness for marriage markets in a similar fashion. We prove that there are marriage markets where no amount of money can guarantee the existence of a fair allocation.

Abstract:
In this note we study von Neumann-Morgenstern farsightedly stable sets for Shapley and Scarf (1974) housing markets. Kawasaki (2008) shows that the set of competitive allocations coincides with the unique von Neumann-Morgenstern stable set based on a farsighted version of antisymmetric weak dominance (cf., Wako, 1999). We demonstrate that the set of competitive allocations also coincides with the unique von Neumann-Morgenstern stable set based on a farsighted version of strong dominance (cf., Roth and Postlewaite, 1977) if no individual is indifferent between his endowment and the endowment of someone else.

Abstract:
Using a bi-choice graph technique (Klaus and Klijn, 2009), we show that a matching for a roommate market indirectly dominates another matching if and only if no blocking pair of the former is matched in the latter (Proposition 1). Using this characterization of indirect dominance, we investigate von Neumann-Morgenstern farsightedly stable sets. We show that a singleton is von Neumann-Morgenstern farsightedly stable if and only if the matching is stable (Theorem 1). We also present roommate markets with no and with a non-singleton von Neumann-Morgenstern farsightedly stable set (Examples 1 and 2).

Abstract:
    The sub-prime crisis has shown a harsh spotlight on the practices of securities underwriters, which provided too many complex securities that proved to ultimately have little value. This uproar calls attention to the fact that the literature on intermediaries has carefully analyzed their incentives, but that we know little about the broader strategic dimensions of this market. The paper explores three related strategic dimensions of the certification market: the publicity given to applications, the coarseness of rating patterns and the sellers' dynamic certification strategies.
    In the model, certifiers respond to the sellers' desire to get a chance to be highly rated and to limit the stigma from rejection. We find conditions under which sellers opt for an ambitious certification strategy, in which they apply to a demanding, but non-transparent certifier and lower their ambitions when rejected. We derive the comparative statics with respect to the sellers' initial reputation, the probability of fortuitous disclosure, the sellers' self-knowledge and impatience, and the concentration of the certification industry. We also analyze the possibility that certifiers opt for a quick turnaround time at the expense of a lower accuracy. Finally, we investigate the opportunity of regulating transparency.

Abstract:
Why do some teams fail to use their members' knowledge effectively, even after they have correctly identified each other's expertise? This paper identifies performance pressure as a critical barrier to effective knowledge utilization. Performance pressure creates threat rigidity effects in teams, meaning that they default to using the expertise of high-status members while becoming less effective at using team members with deep client knowledge. Using a multi-method field study across two professional service firms to refine and test the proposed model, I also find that only the use of client-specific expertise (not the expertise of high-status members) enhances client-rated performance. This paper thus reveals a paradox affecting teams' use of members' knowledge: the more important the project, the less effective the team. This paper contributes to the emerging literature linking team-level expertise utilization (instead of just recognition) with performance outcomes and also adds a novel, team-level perspective to the literature on inter-firm relations.

Abstract:
Female "empowerment" has increasingly become a policy goal, both as an end to itself and as a means to achieving other development goals. Microfinance in particular has often been argued, but not without controversy, to be a tool for empowering women. Here, using a randomized controlled trial, we examine whether access to and marketing of an individually-held commitment savings product leads to an increase in female decision-making power within the household. We find positive impacts, particularly for women who have below median decision-making power in the baseline, and we find this leads to a shift towards female-oriented durables goods purchased in the household.

Abstract:
In 1980, India nationalized its large private banks. This induced different bank ownership patterns across different towns, allowing credible identification of the effects of bank ownership on financial development, lending rates, and the quality of intermediation, as well as employment and investment. Credit markets with nationalized banks experienced faster credit growth during a period of financial repression. Nationalization led to lower interest rates and lower quality intermediation, and may have slowed employment gains in trade and services. Development lending goals were met, but these had no impact on the real economy.

Abstract:
Why is demand for formal financial services low in emerging markets? One view argues that limited cognitive ability and financial literacy stifle demand. A second view argues that demand is rationally low, because formal financial services are expensive and of relatively low value to the poor. This paper uses original surveys and a field experiment to distinguish between two competing answers to this question. Using original survey data from India and Indonesia, we first show that financial literacy is a powerful predictor of demand for financial services. To test the relative importance of literacy and price, we implement a field experiment, offering randomly selected unbanked households financial literacy education, crossed with small incentive (ranging from US $3 to $14) to open bank savings account. We find that the financial literacy program has no effect on the likelihood of opening a bank savings account in the full sample, but do find modest effects for uneducated and financially illiterate households. In contrast, small subsidy payments have a large effect on the likelihood of opening a savings account. These payments are more than two times more cost-effective than the financial literacy training, though this calculation does not take into account any ancillary benefits of financial education.

Abstract:
While scholars contend that firsthand experience — time spent onsite observing the people, places, and norms of a distant locale — is crucial in globally distributed collaboration, how such experience actually affects interpersonal dynamics is poorly understood. Based on 47 semi-structured interviews and 140 survey responses in a global chemical company, this paper explores the effects of firsthand experience on intersite trust. We find firsthand experience leads not just to direct knowledge of the other, but also knowledge of the self as seen through the eyes of the other - what we call "reflected knowledge". Reflected and direct knowledge, in turn, affect trust through identification, adaptation, and reduced misunderstandings.

Abstract:
This paper integrates theories of political budget cycles with theories of tactical electoral redistribution to test for political capture in a novel way. Studying banks in India, I find that government-owned bank lending tracks the electoral cycle, with agricultural credit increasing by 5-10 percentage points in an election year. There is significant cross-sectional targeting, with large increases in districts in which the election is particularly close. This targeting does not occur in non-election years, or in private bank lending. I show capture is costly: elections affect loan repayment, and election year credit booms do not measurably affect agricultural output.

Abstract:
This paper establishes a causal effect of competition from trade liberalization on various characteristics of organizational design. We exploit a unique panel dataset on firm hierarchies (1986-1999) of large U.S. firms and find that increasing competition leads firms to become flatter, i.e., (i) reduce the number of positions between the CEO and division managers (DM), (ii) increase the number of positions reporting directly to the CEO (span of control), (iii) increase DM total and performance-based pay. The results are generally consistent with the explanation that firms redesign their organizations through a set of complementary choices in response to changes in their environment.

Abstract:
As the main producers of managerial elites, business schools represent strategic research sites for understanding the formation of economic practices and representations. This article draws on historical material to analyze the changing place of economics in American business education over the course of the twentieth century. We use the Wharton School as an illustration of the earliest trends and dilemmas (c. 1900-1930), when business schools found themselves caught between their business connections and their striving for moral legitimacy in higher education. We show how several of the school's leaders were closely involved in progressive reforms and presided over the development of the empirical social sciences to address questions of labor regulation and control within manufacturing industries. Next, we look at the creation of the Carnegie Tech Graduate School of Industrial Administration after World War II. This episode illustrates the increasingly successful claims of social scientists, backed by philanthropic foundations, on business education and the growing appeal of "scientific" approaches to decision-making and management. We also show that these transformations were homologically related to changes in the prevailing mode of governance in the American economy: business schools became essential sites for the development of tools and methods for the management of the new large, diversified conglomerates (input-output approaches, linear programming, forecasting). Finally, we argue that the rise of the Chicago Business School from the 1960s onwards marks the decisive ascendancy of economics, and particularly financial economics, in business education over the other behavioral disciplines, as well as the decisive ascendancy of business schools as producers of economic knowledge. By following teacher-student networks, we also document the key role of business schools in diffusing "Chicago-style" economic approaches-offering support for anti-regulatory approaches and popularizing narrowly financial understandings of the firm (Fligstein 1990, 2002), which sociologists have described as characteristic of the modern neo-liberal regime.

Abstract:
Over the period 1975 to 2005, the US dollar (particularly in relation to the Canadian dollar) and the euro and Swiss franc (particularly in the second half of the period) have moved against world equity markets. Thus these currencies should be attractive to risk-minimizing global equity investors despite their low average returns. The risk-minimizing currency strategy for a global bond investor is close to a full currency hedge, with a modest long position in the US dollar. There is little evidence that risk-minimizing investors should adjust their currency positions in response to movements in interest differentials.

Abstract:
Goal setting is one of the most replicated and influential paradigms in the management literature. Hundreds of studies conducted in numerous countries and contexts have consistently demonstrated that setting specific, challenging goals can powerfully drive behavior and boost performance. Advocates of goal setting have had a substantial impact on research, management education, and management practice. In this article, we argue that the beneficial effects of goal setting have been overstated and that systematic harm caused by goal setting has been largely ignored. We identify specific side effects associated with goal setting, including a narrow focus that neglects non-goal areas, a rise in unethical behavior, distorted risk preferences, corrosion of organizational culture, and reduced intrinsic motivation. Rather than dispensing goal setting as a benign, over-the-counter treatment for motivation, managers and scholars need to conceptualize goal setting as a prescription-strength medication that requires careful dosing, consideration of harmful side effects, and close supervision. We offer a warning label to accompany the practice of setting goals.

Abstract:
Gray markets arise when a manufacturer's products are sold outside of its authorized channels, for instance when goods designated for a foreign market are resold domestically. One method multinationals use to combat gray markets is to increase internal transfer prices to foreign subsidiaries in order to increase the gray market's cost base. We illustrate that when a gray market competitor is present, the optimal price for internal transfers exceeds marginal cost, but decreases in the competitiveness of the domestic economy. Moreover, we illustrate that gray markets may cause unintended social welfare consequences when domestic governments mandate the use of arm's length transfer prices between international subsidiaries. Specifically, a shift to arm's length transfer pricing erodes domestic consumer surplus by making the gray market less competitive domestically. Under certain circumstances, the domestic welfare destruction arising from this erosion dominates the domestic welfare gains that accompany a shift to arm's length transfer pricing. Finally, the analysis illustrates that in a gray market setting, the transfer price that maximizes a multinational's profits may also be the same one that maximizes the social welfare of the domestic economy that houses it.

Abstract:
Household financial market participation affects asset prices and household welfare. Yet, our understanding of the participation decision is limited. Using an instrumental variables strategy and dataset new to this literature, we provide the first precise, causal estimates of the effects of education on financial market participation. We find a large effect, even con trolling for income. Examining mechanisms, we demonstrate that cognitive ability increases participation; however, and in contrast to previous research, financial literacy education does not affect decisions. We conclude by discussing how education may affect decision-making through: personality, borrowing behavior, discount rates, risk-aversion, and the influence of employers and neighbors.

Abstract:
We present a model of industry equilibrium to study the coexistence of Open Source (OS) and Proprietary (P) firms. Two novel aspects of the model are: (1) participation in OS arises as the optimal decision of profit-maximizing firms, and (2) OS and P firms may (or may not) coexist in equilibrium. Firms decide their type and investment in R&D, and sell packages composed of a primary good (like software) and a complementary private good. The only difference between both kinds of firms is that OS share their technological advances on the primary good, while P keep their innovations private. The main contribution of the paper is to determine conditions under which OS and P coexist in equilibrium. Interestingly, this equilibrium is characterized by an asymmetric market structure, with a few large P firms and many small OS firms.

Abstract:
The covariance between US Treasury bond returns and stock returns has moved considerably over time. While it was slightly positive on average in the period 1953 - 2005, it was particularly high in the early 1980's and negative in the early 2000's. This paper specifies and estimates a model in which the nominal term structure of interest rates is driven by five state variables: the real interest rate, risk aversion, temporary and permanent components of expected inflation, and the covariance between nominal variables and the real economy. The last of these state variables enables the model to fit the changing covariance of bond and stock returns. Log nominal bond yields and term premia are quadratic in these state variables, with term premia determined mainly by the product of risk aversion and the nominal-real covariance. The concavity of the yield curve-the level of intermediate-term bond yields, relative to the average of short- and long-term bond yields-is a good proxy for the level of term premia. The nominal-real covariance has declined since the early 1980's, driving down term premia.

Abstract:
The need for a fresh approach to U.S. communities is more urgent than ever because of the biggest global economic crisis since the Great Depression. Through examination of the barriers to solving urban problems (and the ways they reinforce each other), this paper offers a new approach to community transformation which calls for leaders to use technology to inform and connect people. We need to convert the social safety net into a social safety network through the creation of smarter communities that are information-rich, interconnected, and able to provide opportunities to all citizens. This process has already begun through such programs as Harlem Children's Zone, Baltimore's CitiStat, Elevate Miami, and others. And they can be replicated. But technology alone is not the answer. Realization of the vision requires leaders to invest in the tools, guide their use, and pave the way for transformation. Perhaps the urgency of the current economic crisis can provide the impetus to overcome resistance to change and turn problems into an opportunity to reduce costs, improve services to communities, and make our cities smarter.

Abstract:
Innovative solutions to pressing global problems require effective inter-cultural communication. We propose that a barrier to the sharing of ideas pertinent to innovation in inter-cultural relationships is low affect-based trust, which arise from individuals' deficits in inter-cultural capability. Results from a study of sample of executives' professional networks indicate that individuals lower in inter-cultural capability are less likely to share new ideas in inter-cultural ties but not intra-cultural ties. This effect is mediated by tie-level affect-based trust but not cognition-based trust. Theoretical and practical implications of these findings are discussed.

Abstract:
The common perception appears to be that vertical integration of advertising services is more the exception than the rule in the U.S. advertising industry. This study investigates the extent of such outsourcing and examines inter-industry variation in the use of in-house rather than independent advertising agencies by U.S. advertisers. While the vast majority of large advertisers employ outside agencies, it comes as a surprise to find that when advertisers of all sizes are considered, about half operate some form of in-house agency. Internalization of advertising services is much more widespread than has hitherto been appreciated and varies widely across industries. To explain this variation, we draw on concepts from research on scale economies and transaction costs to develop a set of hypotheses which we test in cross sectional analyses of data covering 69 two digit SIC industries at two points in time, 1991 and 1999. Across industries, we find that the likelihood of internalization of advertising services decreases as the size of advertising outlays increase but increases as advertising intensity and technological intensity increase and is greater for "creative" industries.

Abstract:
This paper examines the direct private equity investment strategies across sovereign wealth funds and their relationship to the funds' organizational structures. SWFs seem to engage in a form of trend chasing, since they are more likely to invest at home when domestic equity prices are higher, and invest abroad when foreign prices are higher. Funds see the industry P/E ratios of their home investments drop in the year after the investment, while they have a positive change in the year after their investments abroad. SWFs where politicians are involved have a much greater likelihood of investing at home than those where external managers are involved. At the same time, SWFs with external managers tend to invest in lower P/E industries, which see an increase in the P/E ratios in the year after the investment. By way of contrast, funds with politicians involved invest in higher P/E industries, which have a negative valuation change in the year after the investment.

Abstract:
In this paper, we examine the apparent conflict between artistic and commercial objectives within creative companies, taking as our point of departure a particularly energetic debate during a symposium at the 2007 Academy of Management meetings. We surface the assumptions that underlie such debates, compare them with findings from our research on creative industries, and identify three "fallacies" that sometimes enter into discussions of art in relation to money. This, in turn, leads us to propose a framework to support more productive discussion and to describe a direction for management research that might better integrate art and business practices. We conclude that despite an inclination to take offense that often attends the close juxtaposition of art and commerce, which was very much in evidence at that AoM symposium in Philadelphia, the interests of art, artists, and business can be best served if more commerce enters into the world of art, not less.

Abstract:
This paper reports the results of a 2007 experiment testing if specific process simplification can enhance savings by low-to-moderate income (LMI) households. Tax refund recipients at certain H&R Block (Block) tax preparation offices were given the option to purchase U.S. Savings Bonds in addition to existing Block savings products. The fraction of filers who did any savings at the tax-site was 8.5 times higher at these treatment sites offering bonds (7.05%) than at control sites where bonds were not available (0.74%). Even after controlling for filers' demographic factors and self-revealed savings intent, the likelihood of tax-site savings was 5.5 percentage points higher at treatment sites as compared with control sites. In contrast to the take up of many financial products, the rate of bond purchases by less well-to-do families was no lower, and in some cases was higher than for more well-to-do filers. Also, more than 63% of the treatment group savers were individuals who could be deemed to be "asset poor". Bond buyers were more likely than other tax-site savers to have "family-centered" savings goals (i.e., saving for education and/or children/family), were more likely to be married or heads of household, and were more likely to have more dependents. A large majority (69%) of all bond purchasers also bought bonds for others, in effect, "gifting" savings. These results demonstrate that simplification can have an impact on savings rates, that there is substantial additional potential for intra-family gifting, and that simple changes in tax "plumbing" may enhance savings.

Abstract:
We study the competitive and welfare implications when a manufacturer converts its waste stream into a useful and saleable by-product. The term "by-product synergy" has been coined to describe this practice. By converting waste into by-product, the firm not only reduces its waste disposal cost and potentially increases revenue, it may reduce its environmental impact by decreasing waste volume. The distinguishing operational characteristic of by-product synergy is that quantities of the primary product and by-product are linked, with production of the primary product defining the upper bound of the quantity of the by-product. Optimization of a by-product synergy operation requires the firm to shift from a "product and waste" mentality to a "product and product" mentality, and thereby actively manage the quantities of both products to maximize profit. Conditions in the two markets determine whether the firm should increase production of the primary product in order to capture value in the by-product market ("full+ conversion"), or only convert part of its waste into by-product so as not to flood the by-product market ("partial conversion"). As waste is now a useful input for by-product production, it may be optimal to increase the amount of waste generated to improve the efficiency of the by-product process. In addition to the managerial implications, this analysis can inform policy as we show that increasing disposal cost decreases the size of the primary market and increases the size of the by-product market. Therefore, increasing disposal cost decreases the amount of waste generated and, of the waste generated, more is converted into by-product. By-product synergy also shifts wealth from the primary market to the by-product market as disposal cost increases, and under certain conditions, increasing disposal cost may actually increase overall social welfare. We also consider the environmental impact of BPS and derive competitive conditions under which BPS reduces and increases emissions.

This paper examines the litigation of patents relating to financial products and services. I show that these grants are being litigated at a rate 27 to 39 times greater than that of patents as a whole. The patents being litigated are disproportionately those issued to individuals and to smaller, private entities, as well as those whose features may proxy for higher quality. Larger entities are disproportionately targeted in litigation. I discuss how the findings are in large part consistent with the theoretical literature on the economics of litigation.

Abstract:
Why are some places more entrepreneurial than others? We use Census Bureau data to study local determinants of manufacturing startups across cities and industries. Demographics have limited explanatory power. Overall levels of local customers and suppliers are only modestly important, but new entrants seem particularly drawn to areas with many smaller suppliers, as suggested by Chinitz (1961). Abundant workers in relevant occupations also strongly predict entry. These forces plus city and industry fixed effects explain between sixty and eighty percent of manufacturing entry. We use spatial distributions of natural cost advantages to address partially endogeneity concerns.

Abstract:
Recent papers have demonstrated that the way people acquire information about a decision problem, by experience or by abstract description, can affect their behavior. We examine the role of experience over time in the emergence of the Gambler's Fallacy in binary prediction tasks. Theories of the Gambler's Fallacy and models of binary prediction suggest that recency bias, elicited by experience over time, may be necessary for the fallacy to emerge. Experiment 1 compares a condition where participants sequentially predict the colored outcomes of a roulette wheel with a condition where the wheel's past outcomes are presented all at once. Subjects are yoked so that the same history of outcomes is observed in both conditions. The results reveals a tendency towards negative recency when outcomes are experienced that disappears when the same outcomes are presented all at once. Experiment 2 examines a boundary condition where outcomes are presented sequentially in an automatic fashion without intervening predictions. Here too, the Gambler's Fallacy emerges suggesting that it is the mere presentation of information over time that gives rise to the bias. Implications are discussed.

Abstract:
This study examines the European stock market reaction to sixteen events associated with the adoption of International Financial Reporting Standards (IFRS) in Europe. European IFRS adoption represented a major milestone towards financial reporting convergence yet spurred controversy reaching the highest levels of government. We find a more positive reaction for firms with lower quality pre-adoption information, which is more pronounced in banks, and with higher pre-adoption information asymmetry, consistent with investors expecting net information quality benefits from IFRS adoption. We also find that the reaction is less positive for firms domiciled in code law countries, consistent with investors' concerns over enforcement of IFRS in those countries. Finally, we find a positive reaction to IFRS adoption events for firms with high quality pre-adoption information, consistent with investors expecting net convergence benefits from IFRS adoption. Overall, the findings suggest that investors in European firms perceived net benefits associated with IFRS adoption.

Abstract:
Hierarchy is a generic structure in which levels are asymmetrically ordered. In an industry setting, classic supply chains display strict hierarchy, whereas clusters of firms have linkages going in many different directions. Previous theory has often assumed the existence of the hierarchical relationships among firms and empirical work has focused on a single level of an industry or bilateral relationships. However, quantitative evidence on the deep hierarchy in large industrial sectors is lacking. In this paper, we develop metrics and methods to define and measure the degree of hierarchy in transactional relationships among firms, and apply the methods to two large industrial sectors in Japan: automotive and electronics. We compiled the networks of firms connected by transactional relationships. Our empirical analysis shows that the automotive sector exhibits a higher degree of hierarchy than the electronics sector. We further analyze the differences in hierarchy using a simulation model based on transaction breadth and transaction specificity. The empirical measurement and model analysis together indicate that it is the low transaction specificity that drives down the degree of hierarchy in the electronics sector. Differences in transaction patterns in turn may result from the differences in the power level of underlying technologies, which affect product specificity and asset specificity. Thus, the degree of hierarchy in an industry sector may be traced back to fundamental properties of the underlying technologies.

Abstract:
Existing theory of modularity explains how modular designs create value. We extend this theory to address value appropriation. A product or process design that is modular with respect to intellectual property (IP) allows firms to better capture value in situations where knowledge and value creation are distributed across many actors. We use case studies to develop an inductive theory of "IP modularity," from which we derive testable propositions and managerial implications.

Abstract:
We analyze the existence of pure strategy symmetric price equilibria in a generalized version of Salop (1979)'s circular model of competition between differentiated products - namely, we allow consumers to purchase more than one brand. When consumers purchase all varieties from which they derive non-negative net utility, there is no competition, so that each firm behaves like an unconstrained monopolist. When each consumers is interested in purchasing an exogenously given number (n) of varieties, we show that there is no pure strategy symmetric price equilibrium in general (for n > 2 with linear transportation costs). In turn, if the limitation on the number of varieties consumers purchase comes from a budget constraint then we obtain a multiplicity of symmetric price equilibria, which can be indexed by the number of varieties consumers purchase in equilibrium.

Abstract:
Multi-sided platforms (MSPs), which bring together two or more interdependent groups of customers, have recently risen to economic and business prominence in many industries. This paper first lays out a simple micro-founded framework which aims to organize academic and managerial thinking about MSPs. It argues that any MSP performs one or both among two fundamental functions: reducing search costs and reducing shared transaction costs among its multiple sides. Using a variety of illustrations, the framework is then used to formulate general principles driving MSP design and expansion strategies: choosing the relevant platform "sides", deciding which fundamental activities to perform and trading off depth against scope of MSP functions.

Abstract:
People often make judgments about the ethicality of others' behaviors and then decide how harshly to punish such behaviors. When they make these judgments and decisions, sometimes the victims of the unethical behavior are identifiable, and sometimes they are not. In addition, in our uncertain world, sometimes an unethical action causes harm, and sometimes it does not. We argue that a rational assessment of ethicality should not depend on the identifiability of the victim of wrongdoing or the actual harm caused. Yet in four laboratory studies, we show that these factors have a systematic effect on how people judge the ethicality of the perpetrator of an unethical action. Specifically, we find that identifiability of the victim of wrongdoing and information about the outcome of wrongdoing influence both ethical judgments and decisions to punish wrongdoers. Our studies show that people judge behavior as more unethical when (1) identifiable versus statistical victims are involved and (2) the behavior leads to a negative rather than a positive outcome. We also find that people's willingness to punish wrongdoers is consistent with their judgments, and we offer preliminary evidence on how to reduce these biases.

Abstract:
This paper proposes a new approach to improve the way central banks can analyze and manage the financial risks of a national economy. It is based on the modern theory and practice of contingent claims analysis (CCA), which is successfully used today at the level of individual banks by managers, investors, and regulators. The basic analytical tool is the risk-adjusted balance sheet, which shows the sensitivity of the enterprise's assets and liabilities to external "shocks." At the national level, the sectors of an economy are viewed as interconnected portfolios of assets, liabilities, and guarantees-some explicit and others implicit. Traditional approaches have difficulty analyzing how risks can accumulate gradually and then suddenly erupt in a full-blown crisis. The CCA approach is well-suited to capturing such "non-linearities" and to quantifying the effects of asset-liability mismatches within and across institutions. Risk-adjusted CCA balance sheets facilitate simulations and stress testing to evaluate the potential impact of policies to manage systemic risk.

Abstract:
We consider estate division problems, a generalization of bankruptcy problems. We show that in a direct revelation claim game, if the underlying division rule satisfies efficiency, equal treatment of equals, and weak order preservation, then all (pure strategy) Nash equilibria induce equal division. Next, we consider division rules satisfying efficiency, equal treatment of equals, and claims monotonicity. For claim games with at most three agents, again all Nash equilibria induce equal division. Surprisingly, this result does not extend to claim games with more than three agents. However, if nonbossiness is added, then equal division is restored.

In this article, we define good scholarship, highlight our points of disagreement with Locke and Latham (2009), and call for further academic research to examine the full range of goal setting's effects. We reiterate our original claim that goal setting, like a potent medication, can produce both beneficial effects and systematic, negative outcomes (Ordóñez, Schweitzer, Galinsky, & Bazerman, 2009), and as a result, it should be carefully prescribed and closely monitored.

Abstract:
This paper is the (pre-course) introduction document to an experimental course developed by the authors and taught at the U. of Rochester Simon School of Business. The intention of the course is to leave the participants actually being leaders and being able to exercise leadership effectively, and for the course to contribute to creating a new science of leadership. The course is founded on an ontological model of human nature. 

By ontological we mean the following: If you have ever wondered what it would be like to be a bird, or wondered what it is like to be your dog, or to be a person of the opposite gender, or what it is like to be some particular friend of yours, you were in an ontological inquiry.

Ontology as a general subject is concerned with the being of anything.  However, here we are concerned specifically with the ontology of human beings, that is, the being of a human being.

For a narrower and therefore easier example of being, we can talk about being angry, or being antisocial, or being a man or woman of character.  We could examine these ways of being from the comfort of our somewhat familiar perspectives of the science of psychology or neuroscience.

While less familiar for us and therefore perhaps at first uncomfortable, it is also possible to examine any of these ways of being from an ontological perspective. Here we would be examining the being aspect of being angry, or being antisocial, or being a man or woman of character. (Webster’s Dictionary (1998) defines being as “fundamental or essential nature”.)  From this perspective we clearly see that when we are being angry, we are likely to act in anger.  Likewise for being antisocial, or being a man or woman of character. From the ontological perspective it is clear that being constrains and shapes behavior.

The ontological perspective is powerful when dealing with the being of being a leader, and being able to exercise leadership effectively.  Like acting in anger when we are being angry, or acting with ease if we are being at ease, or acting with confidence when we are being confident, if we master the being of being a leader, we are likely to act as a leader, and effectively exercise leadership.  And, this course is about being a leader, and acting effectively in exercising leadership as a natural consequence of being a leader.

Effective leadership does not come from mere knowledge about what leaders do, or trying to emulate the characteristics or styles of noteworthy leaders, or from trying to remember and follow the steps, tips or techniques from books on leadership, and certainly not from merely being in a leadership position, or position of authority.

An epistemological mastery of a subject leaves you knowing.  An ontological mastery of a subject leaves you being.  This course is about access to being a leader, and being able to exercise leadership effectively.

If you are not being a leader, and you try to act like a leader, you are likely to fail.  That’s called being inauthentic, or pretending to be a leader.

If you are being a leader, you will act as a leader.

Our Promise:
You will have experienced whatever personal transformation is required for you to leave the course being who you need to be to be a leader, and with what it takes to exercise leadership effectively.

In other words, you will be a leader.

Abstract:
Platform-mediated networks encompass several distinct types of participants, including end users, complementors, platform providers who facilitate users' access to complements, and sponsors who develop platform technologies. Each of these roles can be opened—that is, structured to encourage participation—or closed. This paper reviews factors that motivate decisions to open or close mature platforms. At the platform provider and sponsor levels, these decisions entail: 1) interoperating with established rival platforms; 2) licensing additional platform providers; or 3) broadening sponsorship. With respect to end users and complementors, decisions to open or close a mature platform involve: 1) backward compatibility with prior platform generations; 2) securing exclusive rights to certain complements; or 3) absorbing complements into the core platform. Over time, forces tend to push both proprietary and shared platforms toward hybrid governance models characterized by centralized control over platform technology (i.e., closed sponsorship) and shared responsibility for serving users (i.e., an open provider role).

Abstract:
We consider the problem of designing truthful mechanisms to minimize the makespan on m unrelated machines. In their seminal paper, Nisan and Ronen [14] showed a lower bound of 2, and an upper bound of m, thus leaving a large gap. They conjectured that their upper bound is tight, but were unable to prove it. Despite many attempts that yield positive results for several special cases, the conjecture is far from being solved: the lower bound was only recently slightly increased to 2.61 [5, 10], while the best upper bound remained unchanged. In this paper we show the optimal lower bound on truthful anonymous mechanisms: no such mechanism can guarantee an approximation ratio better than m. This is the first concrete evidence to the correctness of the Nisan-Ronen conjecture, especially given that the classic scheduling algorithms are anonymous, and all state-of-the-art mechanisms for special cases of the problem are anonymous as well.

Abstract:
We highlight and explain eight lessons from optimal tax theory and compare them to the last few decades of OECD tax policy. As recommended by theory, top marginal income tax rates have declined, marginal income tax schedules have flattened, redistribution has risen with income inequality, and commodity taxes are more uniform and are typically assessed on final goods. However, trends in capital taxation are mixed, and capital income tax rates remain well above the zero level recommended by theory. Moreover, some of theory's more subtle prescriptions, such as taxes that involve personal characteristics, asset-testing, and history-dependence, remain rare in practice. Where large gaps between theory and policy remain, the difficult question is whether policymakers need to learn more from theorists, or the other way around.

Abstract:
Should the income tax include a credit for short taxpayers and a surcharge for tall ones? The standard Utilitarian framework for tax analysis answers this question in the affirmative. Moreover, a plausible parameterization using data on height and wages implies a substantial height tax: a tall person earning $50,000 should pay $4,500 more in tax than a short person. One interpretation is that personal attributes correlated with wages should be considered more widely for determining taxes. Alternatively, if policies such as a height tax are rejected, then the standard Utilitarian framework must fail to capture intuitive notions of distributive justice.

Abstract:
The magnitude of the current financial crisis reflects the failure of an economic and regulatory philosophy that had proved increasingly influential in policy circles over the past three decades.

This paper suggests (1) that contrary to the prevailing wisdom, New Deal policies (including federal deposit insurance and bank supervision) worked to stabilize the financial system; (2) that the financial catastrophe of 2007-2009 was not an accident, but rather a mistake, driven by a deregulatory mindset that took 50 years of post-New Deal financial stability for granted; and (3) that the dramatic federal response to the current financial crisis has created a new reality, in which virtually all systemically significant financial institutions now enjoy an implicit guarantee from the federal government that will continue to exist (and continue to generate moral hazard) long after the immediate crisis passes.

Based on this analysis, one major step that is necessary now to help ensure financial stability in the future is to identify and regulate "systemically significant" institutions on an ongoing basis, rather than simply in the heat of a crisis. To guard against moral hazard (in the face of large implicit guarantees) and to ensure the safety of the broader financial system, these institutions must face significant prudential regulation, they should be required to pay premiums for the federal insurance they already enjoy, and they should be subject to an FDIC-style receivership process in the event of failure.

Abstract:
In this paper, we study managers' errors in decision making for inventory replenishment and how these errors affect their inventory system. In particular, primarily for its expected relationship with the bullwhip effect, we focus on the error of the over-reaction to demand changes and a common contributor of decision making biases: forecasting of demand. By over-reaction we mean that the manager over (under) orders when seeing a change in demand. We show that our representative manifestations of forecasting - managers' subjective response to demand signals and the use of simple quantitative forecasting techniques - share similar consequences: both can result in an increase in internal costs and in the uncertainty and volatility of the system's replenishment orders. Further results of this paper provide argument and thus incentive for mitigating the bullwhip effect by relating it to decision making that would help reduce costs for the manager as well.

Abstract:
This paper presents econometric evidence of two independent effects of adding more competitors on innovation: 1) a competition effect whereby increasing rivalry shapes, and often decreases, incentives to expend effort and invest in innovation; and 2) a parallel search effect whereby adding greater numbers of "searchers" benefits innovation by broadening the search for solutions. We further show the importance of these effects depends on the nature of the innovation problem being solved. The analysis uses data from TopCoder's software contest platform, on which elite software developers were assigned different problems to solve within assigned groups of direct competitors. Econometric relationships are identified by exploiting random assignment and a separate instrumental variables procedure.

Abstract:
This paper presents evidence of performance persistence in entrepreneurship. We show that entrepreneurs with a track record of success are much more likely to succeed than first-time entrepreneurs and those who have previously failed. In particular, they exhibit persistence in selecting the right industry and time to start new ventures. Entrepreneurs with demonstrated market timing skill are also more likely to outperform industry peers in their subsequent ventures. This is consistent with the view that if suppliers and customers perceive the entrepreneur to have market timing skill, and is therefore more likely to succeed, they will be more willing to commit resources to the firm. In this way, success breeds success and strengthens performance persistence.

Abstract:
Phenomenological assumptions—assumptions about the fundamental qualities of the phenomenon being studied and how it relates to the environment in which it occurs—affect the dissemination of knowledge from subfields to the broader field of study. Micro-process research in organizational studies rests on implicit phenomenological assumptions that vary in the extent to which micro-processes are viewed as parts of larger systems. We suggest that phenomenological assumptions linking micro-processes to organizational contexts highlight the relevance of micro-process research findings to broader organizational questions, and therefore increase the likelihood that the findings will disseminate to the larger field of organizational research. We test this assertion by analyzing studies of negotiation published in top peer-reviewed management, psychology, sociology, and industrial relations journals from 1990 to 2005. Our findings reveal a continuum of open systems to closed systems phenomenological assumptions in negotiation research. Analysis of the citation rates of the articles in our data set by non-negotiation organizational research indicates that more open systems assumptions increase the likelihood that a negotiation article will be cited in organizational studies, after controlling for other, previously identified effects on citation rates. Our findings suggest that subfields can increase the impact they have on the broader intellectual discourse by situating their phenomena in rich contexts that illuminate the connections between their findings and questions of interest to the broader field.

Abstract:
In their seminal 1985 paper, Katz and Shapiro study systems compatibility in settings with one-sided platforms and direct network effects. We consider systems compatibility when competing platforms are two-sided and there are indirect network effects to develop an explanation why markets with two-sided platforms are often characterized by incompatibility with one dominant player who may subsidize access to one side of the market. Specifically, we model competitive interaction between two platform providers that act as intermediaries between developers of platform-based products (applications) and users of such products. We show that the unique equilibrium under platform compatibility leads to higher profits than the symmetric equilibrium under incompatibility. Notwithstanding, incompatibility naturally gives rise to asymmetric equilibria with a dominant platform that captures all users and earns more than under compatibility. Our model allows a detailed analysis of social efficiency, and we show that entry by developers is socially excessive (insufficient) if competing platforms are compatible (incompatible). We conclude that while society would be better off if platforms were compatible, the quest for market dominance by competing platform providers prevents them from agreeing to a common standard.

Abstract:
This paper provides a basic conceptual framework for interpreting non-price instruments used by multi-sided platforms (MSPs) by analogizing MSPs as "private regulators" who regulate access to and interactions around the platform. We present evidence on Facebook, TopCoder, Roppongi Hills and Harvard Business School to document the "regulatory" role played by MSPs. We find MSPs use nuanced combinations of legal, technological, informational and other instruments (including price-setting) to implement desired outcomes. Non-price instruments were very much at the core of MSP strategies.

Abstract:
Policies that would create net benefits for society but would also involve costs frequently lack the necessary support to be enacted because losses loom larger than gains psychologically. To reduce this harmful consequence of loss aversion, we propose a new type of policy bundling technique in which related bills that have both costs and benefits are combined. Using a laboratory study, we confirm across a set of four legislative domains that this bundling technique increases support for bills that have both costs and benefits. We also demonstrate that this effect is due to changes in the psychology of decision making, rather than voters' willingness to compromise and support a bill they weakly oppose when that bill is bundled with one they strongly support.

Abstract:
Economic analysis often reviews the role of principles - such as respect for intellectual property rights - in driving innovation. Given the interdependent nature of innovation in information technology, three core principles have emerged that work together to ensure that complementary, interconnected products coexist and compete. These core principles are particularly important when applied to platforms, which have played a central role in enabling the development and distribution of the variety of applications and services that drive the popularity of software. The first principle focuses on enabling choice: firms should allow consumers and partners to have a real choice between complementary products and services from otherwise competing firms (e.g., a browser should enable a consumer to choose a home page provided by a competitor). The second principle focuses on opportunity: specifically, opportunity that is facilitated by giving developers platform access and the ability to innovate and build on platform technologies to create new products and services. The third principle focuses on interoperability: vendors should enable products to work together so customers can realize the full benefit of complementary products offered by competing vendors. Following this principle enables products to connect to each other in appropriately defined ways, and ensures that users can port their data between products securely and reliably. This paper reviews the rationale for these principles and examines their impact on competition in the cloud computing ("internet software") environment.

Abstract:
A long-standing controversy is whether LBOs relieve managers from short-term pressures from public shareholders, or whether LBO funds themselves are driven by short-term profit motives and sacrifice long-term growth to boost short-term performance. We investigate 495 transactions with a focus on one form of long-term activities, namely investments in innovation as measured by patenting activity. We find no evidence that LBOs are associated with a decrease in these activities. Relying on standard measures of patent quality, we find that patents granted to firms involved in private equity transactions are more cited (a proxy for economic importance), show no significant shifts in the fundamental nature of the research, and are more concentrated in the most important and prominent areas of companies' innovative portfolios.

Abstract:
It is often argued that competition forces managers to make better choices, thus favoring managerial autonomy in decision making. I formalize and challenge this idea. Suppose that managers care about keeping their position or avoiding interference, and that they can make strategic choices that affect both the expected profits of the firm and their riskiness. Even if competition at first pushes the manager towards profit maximization as commonly argued, I show that further increases in competitive forces might as well lead him to take excessive risks if the threat on his position is strong enough. To curb this possibility, the principal-owner optimally reduces the degree of autonomy granted to the manager. Hence higher levels of managerial autonomy are more likely for intermediate levels of competition.

Abstract:
This paper identifies a fundamental economic welfare tradeoff between two-sided open platforms and two-sided proprietary (closed) platforms connecting consumers and producers. Proprietary platforms create two-sided deadweight losses through monopoly pricing but at the same time, precisely because they set prices in order to maximize profits, they partially internalize two-sided positive indirect network effects and direct competitive effects on the producer side. We show that this can sometimes make proprietary platforms more socially desirable than open platforms, which runs against the common intuition that open platforms are more efficient. By the same token, inter-platform competition may also turn out to be socially undesirable because it may prevent platforms from sufficiently internalizing indirect externalities and direct intra-platform competitive effects.

Abstract:
Several studies have examined how the ISO 9001 Quality Management System standard affects organizational outcomes such as profits. This is the first large-scale study to examine its effects on employee outcomes such as employment, earnings, and health and safety. We analyzed a matched sample of nearly 1,000 companies in California. ISO 9001 adopters subsequently had far lower organizational death rates than a matched control group of non-adopters. Among surviving employers, ISO adopters realized higher rates of growth of sales, employment, payroll, and average annual earnings. Injury rates also declined slightly at ISO 9001 adopters, although total injury costs did not. These results have implications for organizational theory, managers, and public policy.

Abstract:
This paper provides a simple model of two-sided platforms, in which one side (W) values not just the quantity (i.e. number) of users on the other side (M), but also their average quality in some dimension. In this context, platforms might find it profitable to exclude low-quality users on side M, even though some would be willing to pay the platform access prices. Platforms are more likely to engage in exclusion of low-quality M users when W users place more value on the average quality and less value on the total quantity on side M. Exclusion incentives also depend on the proportion of high-quality users in the overall M population and on their cost advantage in joining the platform, relative to low-quality M users. The net effect of these two factors is ambiguous: it generally depends on whether they have a stronger impact on the gains from exclusion (higher average quality) or on its costs (lower quantity).

Abstract:
Fair and accurate credit ratings arguably play an important role in the financial system. In an environment absent free entry of rating agencies, the provision of quality ratings is at least partially sustained by the reputational concerns of the rating agencies. The economically significant entry of a third agency into a market that was previously best described as a duopoly provides a unique experiment to examine the effect of increased competition on the disciplining effects of reputation. Using a variety of data sources, we find that competition leads to more issuer-friendly and less informative ratings. First, the credit ratings issues by the two incumbent agencies increased toward good ratings. Second, the correlation between bond yields and ratings fell. And lastly, negative stock price responses to announced rating downgrades are larger in absolute value (a downgrade in this weaker ratings environment is even worse news). Ultimately, our findings are consistent with models that suggest competition can impede the reputational mechanism.

Abstract:
The challenges associated with climate change will require governments, citizens, and firms to work collaboratively to reduce greenhouse gas emissions, a task that requires information on companies' emissions levels, risks, and reduction opportunities. This paper explores the conditions under which firms participate in this endeavor. Building on theories of how social activists inspire changes in organizational norms, beliefs, and practices, we hypothesize that shareholder actions and regulatory threats are likely to prime firms to adopt practices consistent with the aims of a broader social movement. We find empirical evidence of direct and spillover effects. In the domain of private politics, shareholder resolutions filed against it and others in its industry increase a firm's propensity to engage in practices consistent with the aims of the related social movement. Similarly, in the realm of public politics, threats of state regulations targeted at a firm's industry as well as regulations targeted at other industries increase the likelihood that the firm will engage in such practices. These findings extend existing theory by showing that both activist groups and government actors can spur changes in organizational practices, and that challenges mounted against a single firm and an industry can inspire both firm and field-level changes.

Abstract:
In the study of law and economics, there is a danger that historical inferences from theory may infect historical tests of theory. It is imperative, therefore, that historical tests always involve a vigorous search not only for confirming evidence, but for disconfirming evidence as well. We undertake such a search in the context of a single well-known case: the Federal Radio Commission's (FRC's) 1927 decision not to expand the broadcast radio band. The standard account of this decision holds that incumbent broadcasters opposed expansion (to avoid increased competition) and succeeded in capturing the FRC. Although successful broadcaster opposition may be taken as confirming evidence for this interpretation, our review of the record reveals even stronger disconfirming evidence. In particular, we find that every major interest group, not just radio broadcasters, publicly opposed expansion of the band in 1927, and that broadcasters themselves were divided at the FRC's hearings.

Abstract:
The Internet's current numbering system is nearing exhaustion: Existing protocols allow only a finite set of computer numbers ("IP addresses"), and central authorities will soon deplete their supply. I evaluate a series of possible responses to this shortage: Sharing addresses impedes new Internet applications and does not seem to be scalable. A new numbering system ("IPv6") offers greater capacity, but network incentives impede transition. Paid transfers of IP addresses would better allocate resources to those who need them most, but unrestricted transfers might threaten the Internet's routing system. I suggest policies to facilitate an IP address "market" while avoiding major negative externalities - mitigating the worst effects of v4 scarcity, while obtaining price discovery and allocative efficiency benefits of market transactions.

Abstract:
The boundaries and contours of design sciences continue to undergo definition and refinement. In many ways, the sciences of design defy disciplinary characterization. They demand multiple epistemologies, theoretical orientations (e.g. construction, analysis or intervention) and value considerations. As our understanding of this emerging field of study grows, we become aware that the sciences of design require a systemic perspective that spans disciplinary boundaries. The Doctoral Consortium at the Design Science Research Conference in Information Sciences and Technology (DESRIST) was an important milepost in their evolution. It provided a forum where students and leading researchers in the design sciences challenged one another to tackle topics and concerns that are similar across different disciplines. This paper reports on the consortium outcomes and insights from mentors who took part in it. We develop a set of observations to guide the evolution of the sciences of design. It is our intent that the observations will be beneficial, not only for IS researchers, but also for colleagues in allied disciplines who are already contributing to shaping the sciences of design.

Abstract:
Tax policy toward American multinational firms would appear to be approaching a crossroads. The presumed linkages between domestic employment conditions and the growth of foreign operations by American firms have led to calls for increased taxation on foreign operations - the so-called "end to tax breaks for companies that ship our jobs overseas." At the same time, the current tax regime employed by the U.S. is being abandoned by the two remaining large capital exporters - the UK and Japan - that had maintained similar regimes. The conundrum facing policymakers is how to reconcile mounting pressures for increased tax burdens on foreign activity with the increasing exceptionalism of American policy. This paper address these questions by analyzing the available evidence on two related claims - i) that the current U.S. policy of deferring taxation of foreign profits represents a subsidy to American firms and ii) that activity abroad by multinational firms represents the displacement of activity that would have otherwise been undertaken at home. These two tempting claims are found to have limited, if any, systematic support. Instead, modern welfare norms that capture the nature of multinational firm activity recommend a move toward not taxing the foreign activities of American firms, rather than taxing them more heavily. Similarly, the weight of the empirical evidence is that foreign activity is a complement, rather than a substitute, for domestic activity. Much as the formulation of trade policy requires resisting the tempting logic of protectionism, the appropriate taxation of multinational firms requires a similar fortitude.

Abstract:
Read the news of recent computer security guffaws, and it's striking how many problems stem from online advertising. Advertising is the bedrock of web sites that are provided without charge to end users, so advertising is everywhere. But advertising security gaps are equally widespread: from "malvertisement" banner ads pushing rogue anti-spyware software, to click fraud, to spyware and adware, the security lapses of online advertising are striking.

During the past five years, I have uncovered hundreds of online advertising scams defrauding thousands of users-not to mention all the web's top merchants. This chapter summarizes some of what I've found-and what users and advertisers can do to protect themselves.

Abstract:
This paper investigates whether presentation of special items within the financial statements reflects the firm's underlying economic performance or opportunism. We examine the presentation of recognized special items either as a separate line item on the income statement or aggregated within another line item with disclosure only in the footnotes. Our study is motivated by standard-setting interest in performance reporting and financial statement presentation, as well as prior research investigating managers' presentation choices in other contexts. Using different constructs of persistence to capture the economics of reported special items, we find evidence consistent across a range of specifications that special items highlighted on the income statement are more transitory than those revealed only in the footnotes. For most special items, these results are consistent with this presentation decision reflecting underlying firm performance. For a subset observations - namely, those likely to reflect "big bath" reporting incentives - we provide limited evidence suggestive of opportunism in this presentation decision.

Abstract:
This article examines, in a series of three studies, how people working in organizational hierarchies wrestle with the challenge of upward voice. We first undertook in-depth exploratory research in a knowledge-intensive multinational corporation in which employee input was considered crucial. Qualitative data collected in 190 interviews with employees from all levels and functions suggest that fear of speaking up, even with pro-organizational suggestions, is pervasive and is driven by a set of common implicit theories about speaking up in organizations. Our second study used scenarios about speaking up to validate and extend these findings through analysis of quantitative and qualitative survey data from 71 individuals in MBA and Executive MBA programs. Our third study developed survey measures of the six implicit voice theories identified in the prior two studies in a new sample of 265 adults with diverse work experience, and examined relationships between these measures and other theoretically driven variables. The results suggest that individuals bring to the workplace specific, measurable beliefs about speaking up, and that these implicit theories operate largely independently of current leader behaviors and other current work experiences. Overall, this research provides support for a novel theoretical explanation for workplace silence based on implicit theories of voice.

Abstract:
We consider one-to-one, one-sided matching (roommate) problems in which agents can either be matched as pairs or remain single. We introduce a so-called bi-choice graph for each pair of stable matchings and characterize its structure. Exploiting this structure we obtain as a corollary the "lone wolf" theorem and a decomposability result. The latter result together with transitivity of blocking leads to an elementary proof of the so-called stable median matching theorem, showing how the often incompatible concepts of stability (represented by the political economist Adam Smith) and fairness (represented by the political philosopher John Rawls) can be reconciled for roommate problems. Finally, we extend our results to two-sided matching problems.
Keywords: fairness, matching, median, stability.

Abstract:
Actors often match with associates on a small set of dimensions that matter most for the particular relationship at hand. In so doing, they are exposed to unanticipated social influences because counterparts have more interests, attitudes, and preferences than would-be associates considered when they first chose to pair. This implies that some apparent social influences (those tied to the rationales for forming the relationship) are endogenous to the matching process, while others (those that are incidental to the formation of the relationship) may be conditionally exogenous, thus enabling causal estimation of peer effects. We illustrate this idea in a new dataset tracking the training and professional activities of academic biomedical scientists. In qualitative and quantitative analyses, we show that scientists match to their postdoctoral mentors based on two dominant factors, geography and scientific focus. They then adopt their advisers' orientations toward commercial science as evidenced by the transmission of patenting behavior, but they do not match on this dimension. We demonstrate this in two-stage models that adjust for the endogeneity of the matching process, using a modification of propensity score estimation and a sample selection correction with valid exclusion restrictions. Furthermore, we draw on qualitative accounts of the matching process recorded in oral histories of the career choices of the scientists in our data. All three methods—qualitative description, propensity score estimators, and those that tackle selection on unobservable factors—are potential approaches to establishing evidence of social influence in partially endogenous networks, and they may be especially persuasive in combination.

Abstract:
Global economic transactions such as foreign direct investment must extend over an institutional abyss between the jurisdiction, and therefore protection, of the states involved. Intergovernmental organizations (IGOs), whose members are states, represent an important attempt to span this abyss. IGOs are mandated variously to smooth economic transactions, facilitate global cooperation, and promote cultural contact and awareness. We use a network approach to demonstrate that the connections between two countries through joint-membership in the same IGOs are associated with a large positive influence on the foreign direct investment that flows between them. Moreover, we show that this effect occurs not only in the case of IGOs that focus on economic issues, but also on those with social and cultural mandates. This demonstrates that relational governance is important and feasible in the global context, and for the most risky transactions. Finally we examine the interdependence between the IGO network and the domestic institutions of states. The interdependence between these global and domestic institutional forms is complex, with target-country democracy being a substitute for economic IGOs, but a complement for social and cultural IGOs.

Abstract:
We consider two-sided matching markets with couples. First, we extend a result by Klaus and Klijn (2005, Theorem 3.3) and show that for any weakly responsive couples market there always exists a "double stable" matching, i.e., a matching that is stable for the couples market and for any associated singles market. Second, we show that for weakly responsive couples markets the associated stable correspondence is (Maskin) monotonic and Nash implementable. In contrast, the correspondence that assigns all double stable matchings is neither monotonic nor Nash implementable.

Abstract:
We consider several notions of setwise stability for many-to-many matching markets with contracts and provide an analysis of the relations between the resulting sets of stable allocations for general, substitutable, and strongly substitutable preferences. Apart from obtaining "set inclusion results" on all three domains, we introduce weak setwise stability as a new stability concept and prove that for substitutable preferences the set of pairwise stable matchings is nonempty and coincides with the set of weakly setwise stable matchings. For strongly substitutable preferences the set of pairwise stable matchings coincides with the set of setwise stable matchings.

Abstract:
This study evaluates the impact of high-skilled immigrants on US technology formation. Specifically, we use reduced-form specifications that exploit large changes in the H-1B visa program. Fluctuations in H-1B admissions levels significantly influence the rate of Indian and Chinese patenting in cities and firms dependent upon the program relative to their peers. Most specifications find weak crowding-in effects or no effect at all for native patenting. Total invention increases with higher admission levels primarily through the direct contributions of ethnic inventors.

Abstract:
While many consumers say they care about issues such as sweatshop labor, the existence of a very small market for ethically-produced products does not reflect this sentiment. One explanation for this discrepancy is that consumers are motivated to use moral disengagement strategies to reduce cognitive dissonance when their desire for a product conflicts with their moral standards. In two studies we show levels of moral disengagement can vary based on one's desire for a product when sweatshop labor is present. Furthermore, we present evidence for a mediated moderation where beliefs about sweatshop labor use moderates the impact of desirability on purchase intention, and moral disengagement mediates this process. Motivated mechanisms of moral disengagement are relevant in moral psychology, and have public policy implications.

Abstract:
The purpose of this paper is to show that allowing for taste heterogeneity does not address the similarity critique of discrete-choice models. Although IIA may technically be broken in aggregate, the mixed logit model allows neither a given individual nor the population as a whole to behave with perfect substitution when facing perfect substitutes. Thus, the mixed logit model implies that individuals behave inconsistently across choice sets.
   Estimating the mixed logit on data in which individuals do behave consistently can result in biased parameter estimates, with the individuals' tastes for desirable attributes being systemically undervalued.

Abstract:
Organizations often experience difficulty when pursuing new technology. Large bodies of research have examined the behavioral, social, and cognitive forces that underlie this phenomenon; however, the role of a firm's identity remains relatively unexplored. Identity comprises insider and outsider perceptions of what is core about an organization. An identity has associated with it a set of codes or norms that represent shared beliefs about legitimate behavior for an organization with that identity. In this paper, technologies that deviate from the expectations associated with an organization's identity are labeled identity-challenging technologies. Based on a comprehensive field-based case study of the entire life history of a company, identity-challenging technologies are found to be difficult to capitalize on for two reasons. First, identity serves as a filter, such that organizational members notice and interpret external stimuli in a manner consistent with the identity. As a result, identity-challenging technological opportunities inconsistent with that identity may be missed. Second, since identity becomes intertwined in the routines, procedures, and beliefs of both organizational and external constituents, explicit efforts to shift identity in order to accommodate identity-challenging technology are difficult to accomplish. Given the disruptive nature of identity shifts, understanding whether technology is identity-challenging is a critical consideration for managers pursuing new technology.

Abstract:
We develop a model in which innovations in an economy's growth potential are an important driving force of the business cycle. The framework shares the emphasis of the recent "new shock" literature on revisions of beliefs about the future as a source of fluctuations, but differs by tieing these beliefs to fundamentals of the evolution of the technology frontier. An important feature of the model is that the process of moving to the frontier involves costly technology adoption. In this way, news of improved growth potential has a positive effect on current hours. As we show, the model also has reasonable implications for stock prices. We estimate our model for data post-1984 and show that the innovations shock accounts for nearly a third of the variation in output at business cycle frequencies. The estimated model also accounts reasonably well for the large gyration in stock prices over this period. Finally, the endogenous adoption mechanism plays a significant role in amplifying other shocks.

Abstract:
We develop a framework to empirically examine how politicians with electoral pressures control bureaucrats with career concerns as well as the consequences for bureaucrats' career investments. Unique micro-level data on Indian bureaucrats support our key predictions. Politicians use frequent reassignments (transfers) across posts of varying importance to control bureaucrats. High-skilled bureaucrats face less frequent political transfers and lower variability in the importance of their posts. We find evidence of two alternative paths to career success: officers of higher initial ability are more likely to invest in skill, but caste affinity to the politician's party base also helps secure important positions.

Abstract:
It is often difficult for donors to predict the value of charitable giving because they know little about the persons who receive their help. This concern is particularly acute when making contributions to organizations that serve heterogeneous populations. While we have considerable evidence that donors are more generous if they know their assistance benefits a preferred group, we know little about the demand for such information. To start closing this gap, we study transfers of income to real-world poor people in the context of dictator games. Our dictators can purchase signals about why the recipients are poor. We find that a third of the dictators are willing to pay a dollar to learn more about their recipient. Dictators who devote resources to acquiring information are individuals whose giving is particularly responsive to recipient type. They use the information mainly to withhold resources from "undeserving" types, leading to a drastic decline in aggregate transfers. With endogenous information about recipients, we find that all types of poor subjects are worse off. Our results suggest that the effects of truth-in-giving policies are highly responsive to recipient heterogeneity and biased against more generous giving.

Abstract:
        Has greater turbulence among firms fueled rising wage instability in the U.S.? Gottschalk and Moffitt [1994] find that rising earnings instability was responsible for one third to one half of the rise in wage inequality during the 1980s. These growing transitory fluctuations remain largely unexplained. To help fill this gap, this paper further documents the recent rise in transitory fluctuations in compensation and investigates its linkage to the concurrent rise in volatility of firm performance documented by Comin and Mulani [2006].
        We find strong support for the hypothesis that rising high-frequency turbulence in the sales of large publicly-traded U.S. firms over the past three decades has raised their workers' high-frequency wage volatility. The evidence comes from two data sets: the Panel Study of Income Dynamics (detailed longitudinal information on workers), and COMPUSTAT (detailed firm information, plus average wage and employment levels). Through controls and instrumental variable probes, we rule out straightforward compositional churning as an explanation for the link between firm sales and wage volatility. We also observe that the relationship between sales and wage volatility at the firm level is stronger since 1980, is present only in large companies and is stronger in services than in manufacturing companies.

Abstract:
Many markets have "unraveled" and experienced inefficient, early, dispersed transactions, and subsequently developed institutions to delay transaction timing. However, it has previously proved difficult to measure and identify the resulting efficiency gains. Prior to 1992, college football teams were matched for post-season play up to several weeks before the end of the regular season. Since 1992, the market has reorganized to postpone this matching. We show that the matching of teams affects efficiency as measured by the resulting television viewership, and the reorganization promoted more efficient matching, chiefly due to the increased ability of later matching to produce "championship" games.

Abstract:
      This paper investigates the causes and welfare consequences of unravelling in two-sided matching markets. It shows that similarity of preferences is an important factor driving unravelling. In particular, it shows that under the ex-post stable mechanism (the mechanism that the literature focuses on), unravelling is more likely to occur when participants have more similar preferences. It also shows that any Pareto-optimal mechanism must prevent unravelling, and that the ex-post stable mechanism is Pareto-optimal if and only if it prevents unravelling.

Abstract:
Prior work in organizational learning has failed to find a consistent effect of variation in experience on performance. While some studies find a positive relationship between these two variables, others find no effect or even a negative relationship. In this paper, we suggest that the differences in prior findings may be due to the failure to separate the processes of knowledge acquisition and knowledge application. While variation in experience may permit the acquisition of valuable knowledge, additional mechanisms may be necessary to enable the subsequent application of that knowledge in a team setting. We hypothesize that team familiarity - prior experience working with team members - may be such a mechanism. We use detailed project- and individual-level data from an Indian software services firm to examine the effects of team familiarity and variation in market experience on multiple measures of performance for over 1,100 software development projects Consistent with prior work, we find mixed results for the effect of variation in experience on performance. We do, however, see evidence of a moderating effect of team familiarity on the relationship between these two variables. Our paper identifies one mechanism for uniting knowledge acquisition and knowledge application and provides insight into how the management of experience accumulation affects the development of organizational capabilities.

Abstract:
In settings ranging from product development to service delivery, fluid teams of individuals with different sets of experience are tasked with projects that are critical to their organization's success. Although building teams from individuals with different prior experience is increasingly necessary, prior work examining the relationship between experience and performance fails to find a consistent effect of variation in experience on performance. The problem is that variation in experience improves a team's information processing capacity and knowledge base, but also creates coordination challenges. We hypothesize that team familiarity - team members' prior experience working with one another - is one mechanism that helps teams leverage the potential benefits of variation in team member experience by alleviating coordination problems that such variation may create. We use several years of detailed project- and individual-level data from an Indian software services firm, Wipro Technologies, to examine the effects of team familiarity and variation in experience on multiple measures of performance for software development projects. In most cases, we do not find evidence of a significant main effect for variation in experience on performance. However, when we examine the interaction of team familiarity and variation in experience, we see a complementary effect on measures of delivery performance (i.e., a project being delivered on time and on budget). In team familiarity, our paper identifies one mechanism for capturing the performance benefits of variation in experience and provides insight into how the broader management of experience accumulation affects team performance.

Abstract:
This paper examines virtual team learning in new product development situations. New product development activities manifest novelty, uncertainty and complexity, presenting an extreme need for learning in the course of the work. We present data from an exploratory study of learning processes in globally dispersed new product development teams. These qualitative data are used to investigate components of team learning previously highlighted in the team learning literature-namely reflection-oriented and action-oriented behaviors-and to examine the boundaries of these learning behaviors. We find that effective virtual teams, like co-located teams, engage in both reflective and action-oriented learning behaviors. However, the virtual context highlights distinct participation strategies in teams' learning patterns, which aim to leverage deep, specialist knowledge, on one hand, or seek to integrate diverse knowledge, on the other hand. Moreover, our findings suggest that, in the virtual setting, the boundary of team membership is not centrally associated with different learning behaviors and outcomes, as argued in other team learning research. Instead, virtual team learning behaviors are likely to be shaped by boundaries that delimit timely access to relevant knowledge and skill. In conclusion, we discuss implications for future virtual team learning research.

Abstract:
In an ethnographic study comprised of interviews and concurrent observations of 145 globally distributed members of nine project teams of an organization, we found that uneven proficiency in English, the lingua franca, disrupted collaboration for both native and non-native speakers. Although all team members spoke English, different levels of fluency contributed to tensions on these teams. As non-native English speakers attempted to counter the apprehension they felt when having to speak English and native English speakers fought against feeling excluded and devalued, a cycle of negative emotion ensued and disrupted interpersonal relationships on these teams. We describe in detail how emotions and actions evolved recursively as coworkers sought to relieve themselves of negative emotions prompted by the lingua franca mandate and inadvertently behaved in ways that triggered negative responses in distant coworkers. Our results add to the scant literature on the role of emotions in collaborative relationships in organizations and suggest that organizational policies can set in motion a cycle of negative emotions that interfere with collaborative work.

Abstract:
We assemble a dataset on technology adoption in 1000 B.C., 0 A.D., and 1500 A.D. for the predecessors to today's nation states. We find that this very old history of technology adoption is surprisingly significant for today's national development outcomes. Our strong and robust results are for 1500 A.D. determining per capita income today. We find technological persistence across long epochs: from 1000 BC to 0 AD, from 0 AD to 1500 AD, and from 1500 AD to the present. Although the data allow only some suggestive tests of rival hypotheses to explain long?run technological persistence, we find the evidence to be most consistent with a model of endogenous technology adoption where the cost of adopting new technologies declines sufficiently with the current level of adoption. The evidence is less consistent with a dominant role for population as predicted by the semi?endogenous growth models or for country-level factors like culture, genes or institutions.

Abstract:
Organizations struggle to balance simultaneous imperatives to exploit and explore, yet theorists differ as to whether exploitation undermines or enhances exploration. The debate reflects a gap: the missing theoretical mechanism by which organizations break free of old routines and discover new ones. We propose that the missing link is perturbation: novel stimuli that disrupt the execution of specialized routines. Perturbation creates opportunities for organizations to invoke exploratory, general-purpose problem-solving routines. In mature organizations, exogenous perturbations become increasingly scarce to the point that exploration is stifled and inertia sets in. We theorize that mature organizations can sustain exploration by deliberately inducing perturbations in their own processes. Our theory yields testable hypotheses about the relationships between exploitation, perturbation, and exploration. We provide illustrations from The Toyota Motor Company to show how deliberate perturbation enables efficient exploration in the midst of intense exploitation.

Abstract:
We develop an economic theory of GAAP under the assumption that GAAP's objective is to facilitate efficient capital allocation within an economy. The theory predicts that GAAP as shaped by the economic forces of demand for and supply of financial information would focus on performance measurement and control through the income statement and balance sheet. In addition, the theory allows us to compare and contrast extant GAAP, as produced in a regulated setting, with a GAAP that might arise endogenously as a result of market forces. We conclude that verifiability and conservatism, while detracting accounting from a valuation objective, are critical features of an economic GAAP. We recognize the advantage of using fair values in circumstances where these are based on observable prices in liquid secondary markets, but caution against expanding fair values to areas such as intangibles where their opportunistic use is predictable. We conclude that the convergence project between the FASB and IASB should be dismantled and that competition between the two bodies would be the most practical means of achieving an economic GAAP.

Abstract:
Prior research has found mixed evidence for the long-theorized link between religiosity and pro-social behavior. To help overcome this divergence, we hypothesize that pro-social behavior is linked not to religiosity per se, but rather to the salience of religion and religious norms. We report on a field experiment that examines when auction participants will respond to an appeal to continue bidding for secular charitable causes. The results reveal that religious individuals are more likely than non-religious individuals to respond to an appeal "for charity" only on days that they visit their place of worship; on other days of the week, religiosity has no effect. Notably, the result persists after controlling for a host of factors that may influence bidding, but disappears when the appeal "for charity" is replaced by an appeal to bid for other reasons. Implications for the link between religion and pro-social behavior are discussed.

Abstract:
Can a country grow faster by saving more? We address this question both theoretically and empirically. In our theoretical model, growth results from innovations that allow local sectors to catch up with frontier technology. In poor countries, catching up requires the cooperation of a foreign investor who is familiar with the frontier technology and a domestic entrepreneur who is familiar with local conditions. In such a country, domestic saving matters for innovation, and therefore growth, because it enables the local entrepreneur to put equity into this cooperative venture, which mitigates an agency problem that would otherwise deter the foreign investor from participating. In rich countries, domestic entrepreneurs are already familiar with frontier technology and therefore do not need to attract foreign investment to innovate, so domestic saving does not matter for growth. A cross-country regression shows that lagged savings is positively associated with productivity growth in poor countries but not in rich countries. The same result is found when the regression is run on data generated by a calibrated version of our theoretical model.

Abstract:
A consumer-oriented model for drug development and use has attracted attention in recent years as an alternative to the much-maligned approach of mass-marketing blockbuster drugs. In a parallel development, patients and disease-based organizations have assumed greater roles in defining disease categories than in the past and now influence clinical trials and participate in regulatory decision-making. Yet these developments are far from universal and are taking very different forms around the world. Building on data showing that pharmaceutical firms headquartered in the United States have performed well since 1980 when compared to firms in Europe or Asia (measured both by sales and by numbers of new product introductions), this essay explores the interplay of regulation, definitions of "patient" and "consumer," and centers of power for the pharmaceutical industry. A comparison of the United States and Germany in particular, and the United States and European Union more generally, suggests that how countries resolve tensions between protecting patients and empowering consumers will impact the international competitive standing of their domestic pharmaceutical industries.

Abstract:
In a sample of 102 non-European Union countries, we study variations in the decision to adopt International Financial Reporting Standards (IFRS). There is evidence that more powerful countries are less likely to adopt IFRS, consistent with more powerful countries being less willing to surrender standard-setting authority to an international body. There is also evidence that the likelihood of IFRS adoption at first increases and then decreases in the quality of countries' domestic governance institutions, consistent with IFRS being adopted when governments are capable of timely decision making and when the opportunity and switching cost of domestic standards are relatively low. We do not find evidence that levels of and expected changes in foreign trade and investment flows in a country affect its adoption decision: thus, we cannot confirm that IFRS lowers information costs in more globalized economies. Consistent with the presence of network effects in IFRS adoption, we find that a country is more likely to adopt IFRS if its trade partners or countries within in its geographical region are IFRS adopters.

Abstract:
We analyze the incentives to divert search for an information intermediary who enables buyers (consumers) to search affiliated sellers (stores). There are three motives for diverting search (i.e. inducing consumers to search more than they would like): i) trading off higher total consumer traffic for higher revenues per consumer visit; ii) reducing the variance of store profits when store affiliation decisions are endogenous; and iii) influencing stores' choices of strategic variables (e.g. pricing) once they have decided to affiliate. We show that search diversion remains a necessary strategic instrument for the intermediary even when the contracting space is significantly enriched: allowing the intermediary to charge consumers fixed fees, to offer them screening contracts, to subsidize search; allowing stores' strategic decisions to be contractible or controlled by the intermediary.
