  1. Financing Innovation

    William R. Kerr and Ramana Nanda

    We review the recent literature on the financing of innovation, inclusive of large companies and new startups. This research strand has been very active over the past five years, generating important new findings, questioning some long-held beliefs, and creating its own puzzles. Our review outlines the growing body of work that documents a role for debt financing related to innovation. We highlight the new literature on learning and experimentation across multi-stage innovation projects and how this impacts optimal financing design. We further highlight the strong interaction between financing choices for innovation and changing external conditions, especially reduced experimentation costs.

  2. Global Collaborative Patents

    Sari Pekkala Kerr and William R. Kerr

    We study the prevalence and traits of global collaborative U.S. patents for U.S. public companies, defi…ned to be patents with at least one inventor inside the United States and one abroad. Collaborative patents are frequently observed when a U.S. public company is entering into a new foreign region for innovative work, especially in less developed settings where intellectual property protection is weak. Collaborative patents are also more frequent when the U.S.-based workforce of the fi…rm has a strong ethnic component to it, refl‡ective of global high-skilled migration. Collaborative patents tend to perform similarly to patents developed by the same companies using exclusively U.S.-based teams, and both of these groups are stronger than those developed with exclusively foreign inventor teams.

  3. Heterogeneous Technology Diffusion and Ricardian Trade Patterns

    William R. Kerr

    This study tests the importance of Ricardian technology differences for international trade. The empirical analysis has three comparative advantages: including emerging and advanced economies, isolating panel variation regarding the link between productivity and exports, and exploiting heterogeneous technology diffusion from immigrant communities in the United States for identification. The latter instruments are developed by combining panel variation on the development of new technologies across U.S. cities with historical settlement patterns for migrants from countries. The instrumented elasticity of export growth on the intensive margin with respect to the exporter's productivity growth is between 1.6 and 2.4 depending upon weighting.

  4. U.S. High-Skilled Immigration, Innovation, and Entrepreneurship: Empirical Approaches and Evidence

    William R. Kerr

    High-skilled immigrants are a very important component of U.S. innovation and entrepreneurship. Immigrants account for roughly a quarter of U.S. workers in these fields, and they have a similar contribution in terms of output measures like patents or firm starts. This contribution has been rapidly growing over the last three decades. In terms of quality, the average skilled immigrant appears to be better trained to work in these fields, but conditional on educational attainment of comparable quality to natives. The exception to this is that immigrants have a disproportionate impact among the very highest achievers (e.g., Nobel Prize winners). Studies regarding the impact of immigrants on natives tend to find limited consequences in the short-run, while the results in the long-run are more varied and much less certain. Immigrants in the United States aid business and technology exchanges with their home countries, but the overall effect that the migration has on the home country remains unclear. We know very little about return migration of workers engaged in innovation and entrepreneurship, except that it is rapidly growing in importance.

  5. Innovation, Reallocation and Growth

    Daron Acemoglu, Ufuk Akcigit, Nicholas Bloom and William R. Kerr

    We build a model of firm-level innovation, productivity growth and reallocation featuring endogenous entry and exit. A key feature is the selection between high- and low-type firms, which differ in terms of their innovative capacity. We estimate the parameters of the model using detailed US Census micro data on firm-level output, R&D and patenting. The model provides a good fit to the dynamics of firm entry and exit, output and R&D, and its implied elasticities are in the ballpark of a range of micro estimates. We find industrial policy subsidizing either the R&D or the continued operation of incumbents reduces growth and welfare. For example, a subsidy to incumbent R&D equivalent to 5% of GDP reduces welfare by about 1.5% because it deters entry of new high-type firms. On the contrary, substantial improvements (of the order of 5% improvement in welfare) are possible if the continued operation of incumbents is taxed while at the same time R&D by incumbents and new entrants is subsidized. This is because of a strong selection effect: R&D resources (skilled labor) are inefficiently used by low-type incumbent firms. Subsidies to incumbents encourage the survival and expansion of these firms at the expense of potential high-type entrants. We show that optimal policy encourages the exit of low-type firms and supports R&D by high-type incumbents and entry.

  6. Growth through Heterogeneous Innovations

    Ufuk Akcigit and William R. Kerr

    We study how exploration versus exploitation innovations impact economic growth through a tractable endogenous growth framework that contains multiple innovation sizes, multi-product firms, and entry/exit. Firms invest in exploration R&D to acquire new product lines and exploitation R&D to improve their existing product lines. We model and show empirically that exploration R&D does not scale as strongly with firm size as exploitation R&D. The resulting framework conforms to many regularities regarding innovation and growth differences across the firm size distribution. We also incorporate patent citations into our theoretical framework. The framework generates a simple test using patent citations that indicates that entrants and small firms have relatively higher growth spillover effects.

  7. Is India's Manufacturing Sector Moving Away from Cities?

    Ejaz Ghani, Arti Grover Goswami and William R. Kerr

    This paper investigates the urbanization of the Indian manufacturing sector by combining enterprise data from formal and informal sectors. We find that plants in the formal sector are moving away from urban and into rural locations, while the informal sector is moving from rural to urban locations. While the secular trend for India's manufacturing urbanization has slowed down, the localized importance of education and infrastructure have not. Our results suggest that districts with better education and infrastructure have experienced a faster pace of urbanization, although higher urban-rural cost ratios cause movement out of urban areas. This process is associated with improvements in the spatial allocation of plants across urban and rural locations. Spatial location of plants has implications for policy on investments in education, infrastructure, and the livability of cities. The high share of urbanization occurring in the informal sector suggests that urbanization policies that contain inclusionary approaches may be more successful in promoting local development and managing its strains than those focused only on the formal sector.

  8. The Ethnic Composition of U.S. Inventors

    William R. Kerr

    The ethnic composition of US scientists and engineers is undergoing a significant transformation. This study applies an ethnic-name database to individual patent records granted by the United States Patent and Trademark Office to document these trends with greater detail than previously available. Most notably, the contributions of Chinese and Indian scientists to US technology formation increase dramatically in the 1990s, before noticeably leveling off after 2000 and declining in the case of India. Growth in ethnic innovation is concentrated in high-tech sectors; the institutional and geographic dimensions are further characterized.

  1. Transition to Clean Technology

    Daron Acemoglu, Ufuk Akcigit, Douglas Hanley and William R. Kerr

    We develop a microeconomic model of endogenous growth where clean and dirty technologies compete in production and innovation, in the sense that research can be directed to either clean or dirty technologies. If dirty technologies are more advanced to start with, the potential transition to clean technology can be difficult both because clean research must climb several rungs to catch up with dirty technology and because this gap discourages research effort directed towards clean technologies. Carbon taxes and research subsidies may nonetheless encourage production and innovation in clean technologies, though the transition will typically be slow. We characterize certain general properties of the transition path from dirty to clean technology. We then estimate the model using a combination of regression analysis on the relationship between R&D and patents, and simulated method of moments using microdata on employment, production, R&D, firm growth, entry and exit from the US energy sector. The model's quantitative implications match a range of moments not targeted in the estimation quite well. We then characterize the optimal policy path implied by the model and our estimates. Optimal policy makes heavy use of research subsidies as well as carbon taxes. We use the model to evaluate the welfare consequences of a range of alternative policies.

  2. Highway to Success: The Impact of the Golden Quadrilateral Project for the Location and Performance of Indian Manufacturing

    Ejaz Ghani, Arti Grover Goswami and William R. Kerr

    We investigate the impact of the Golden Quadrilateral (GQ) highway project on the Indian organized manufacturing sector using enterprise data. The GQ project upgraded the quality and width of 5,846 km of roads in India. We use a difference-in-difference estimation strategy to compare non-nodal districts based upon their distance from the highway system. We find several positive effects for non-nodal districts located 0–10 km from GQ that are not present in districts 10–50 km away, most notably higher entry rates and increases in plant productivity. These results are not present for districts located on another major highway system, the North-South East-West corridor (NS-EW). Improvements for portions of the NS-EW system were planned to occur at the same time as GQ but were subsequently delayed. Additional tests show that the GQ project's effect operates in part through a stronger sorting of land-intensive industries from nodal districts to non-nodal districts located on the GQ network. The GQ upgrades further helped spread economic activity to moderate-density districts and intermediate cities.

  3. Entrepreneurship as Experimentation

    William R. Kerr, Ramana Nanda and Matthew Rhodes-Kropf

    Entrepreneurship research is on the rise, but many questions about its fundamental nature still exist. We argue that entrepreneurship is about experimentation: the probabilities of success are low, extremely skewed, and unknowable until an investment is made. At a macro level, experimentation by new firms underlies the Schumpeterian notion of creative destruction. However, at a micro level, investment and continuation decisions are not always made in a competitive Darwinian contest. Instead, a few investors make decisions that are impacted by incentive, agency, and coordination problems, often before a new idea even has a chance to compete in a market. We contend that costs and constraints on the ability to experiment alter the type of organizational form surrounding innovation and influence when innovation is more likely to occur. These factors not only govern how much experimentation is undertaken in the economy, but also the trajectory of experimentation, with potentially very deep economic consequences.

  4. Income Inequality and Social Preferences for Redistribution and Compensation Differentials

    William R. Kerr

    In cross-sectional studies, countries with greater income inequality typically exhibit less support for government-led redistribution and greater acceptance of wage inequality (e.g., United States versus Western Europe). If individual nations evolve along this pattern, a vicious cycle could form with reduced social concern amplifying primal increases in inequality due to forces like skill-biased technical change. Exploring movements around these long-term levels, however, this study finds mixed evidence regarding the vicious cycle hypothesis. On one hand, larger compensation differentials are accepted as inequality grows. This growth in differentials is of a smaller magnitude than the actual increase in inequality, but it is nonetheless positive and substantial in size. Weighing against this, growth in inequality is met with greater support for government-led redistribution to the poor. These patterns suggest that short-run inequality shocks can be reinforced in the labor market but do not result in weaker political preferences for redistribution.

  5. Agglomerative Forces and Cluster Shapes

    William R. Kerr and Scott Duke Kominers

    We model spatial clusters of similar firms. Our model highlights how agglomerative forces lead to localized, individual connections among firms, while interaction costs generate a defined distance over which attraction forces operate. Overlapping firm interactions yield agglomeration clusters that are much larger than the underlying agglomerative forces themselves. Empirically, we demonstrate that our model's assumptions are present in the structure of technology and labor flows within Silicon Valley and its surrounding areas. Our model further identifies how the lengths over which agglomerative forces operate influence the shapes and sizes of industrial clusters; we confirm these predictions using variations across patent technology clusters.

  6. Political Reservations and Women's Entrepreneurship in India

    Ejaz Ghani, William R. Kerr and Stephen D. O'Connell

    We quantify the link between the timing of state-level implementations of political reservations for women in India with the role of women in India's manufacturing sector. While overall employment of women in manufacturing does not increase after the reforms, we find significant evidence that more women-owned establishments were created in the unorganized/informal sector. These new establishments were concentrated in industries where women entrepreneurs have been traditionally active and the entry was mainly found among household-based establishments. We measure and discuss the extent to which this heightened entrepreneurship is due to channels like greater finance access or heightened inspiration for women entrepreneurs.

  7. Skilled Immigration and the Employment Structures of U.S. Firms

    Sari Pekkala Kerr, William R. Kerr and William F. Lincoln

    We study the impact of skilled immigrants on the employment structures of U.S. firms using matched employer-employee data. Unlike most previous work, we use the firm as the lens of analysis to account for a greater level of heterogeneity and the fact that many skilled immigrant admissions are driven by firms themselves (e.g., the H-1B visa). OLS and IV specifications find rising overall employment of skilled workers with increased skilled immigrant employment by firm. Employment expansion is greater for younger natives than their older counterparts, and departure rates for older workers appear higher for those in STEM occupations compared to younger workers.

  8. Entrepreneurship and Urban Growth: An Empirical Assessment with Historical Mines

    Edward L. Glaeser, Sari Pekkala Kerr and William R. Kerr

    Measures of entrepreneurship, such as average establishment size and the prevalence of start-ups, correlate strongly with employment growth across and within metropolitan areas, but the endogeneity of these measures bedevils interpretation. Chinitz (1961) hypothesized that coal mines near Pittsburgh led that city to specialization in industries, like steel, with significant scale economies and that those big firms led to a dearth of entrepreneurial human capital across several generations. We test this idea by looking at the spatial location of past mines across the United States: proximity to historical mining deposits is associated with bigger firms and fewer start-ups in the middle of the 20th century. We use mines as an instrument for our entrepreneurship measures and find a persistent link between entrepreneurship and city employment growth; this connection works primarily through lower employment growth of start-ups in cities that are closer to mines. These effects hold in cold and warm regions alike and in industries that are not directly related to mining, such as trade, finance and services. We use quantile instrumental variable regression techniques and identify mostly homogeneous effects throughout the conditional city growth distribution.

  9. The Dynamics of Firm Lobbying

    William R. Kerr, William F. Lincoln and Prachi Mishra

    We study the determinants of the dynamics of firm lobbying behavior using a panel data set covering 1998–2006. Our data exhibit three striking facts: (i) few firms lobby, (ii) lobbying status is strongly associated with firm size, and (iii) lobbying status is highly persistent over time. Estimating a model of a firm's decision to engage in lobbying, we find significant evidence that up-front costs associated with entering the political process help explain all three facts. We then exploit a natural experiment in the expiration in legislation surrounding the H-1B visa cap for high-skilled immigrant workers to study how these costs affect firms' responses to policy changes. We find that companies primarily adjusted on the intensive margin: the firms that began to lobby for immigration were those who were sensitive to H-1B policy changes and who were already advocating for other issues, rather than firms that became involved in lobbying anew. For a firm already lobbying, the response is determined by the importance of the issue to the firm's business rather than the scale of the firm's prior lobbying efforts. These results support the existence of significant barriers to entry in the lobbying process.

  10. Spatial Determinants of Entrepreneurship in India

    Ejaz Ghani, William R. Kerr and Stephen O'Connell

    We analyze the spatial determinants of entrepreneurship in India in the manufacturing and services sectors. Among general district traits, quality of physical infrastructure and workforce education are the strongest predictors of entry, with labor laws and household banking quality also playing important roles. Looking at the district-industry level, we find extensive evidence of agglomeration economies among manufacturing industries. In particular, supportive incumbent industrial structures for input and output markets are strongly linked to higher establishment entry rates. We also find substantial evidence for the Chinitz effect where small local incumbent suppliers encourage entry. The importance of agglomeration economies for entry hold when considering changes in India's incumbent industry structures from 1989, determined before large-scale deregulation began, to 2005.

  11. Diasporas and Outsourcing: Evidence from oDesk and India

    Ejaz Ghani, William R. Kerr and Christopher Stanton

    This study examines the role of the Indian diaspora in the outsourcing of work to India. Our data are taken from oDesk, the world's largest online platform for outsourced contracts, where India is the largest country in terms of contract volume. We use an ethnic name procedure to identify ethnic Indian users of oDesk in other countries around the world. We find very clear evidence that diaspora-based links matter on oDesk, with ethnic Indians in other countries 32% (9 percentage points) more likely to choose a worker in India. Yet, the size of the Indian diaspora on oDesk and the timing of its effects make clear that the Indian diaspora was not a very important factor in India becoming the leading country on oDesk for fulfilling work. In fact, multiple pieces of evidence suggest that diaspora use of oDesk increases with familiarity of the platform, rather than a scenario where diaspora connections serve to navigate uncertain environments. We further show that diaspora-based contracts mainly serve to lower costs for the company contacts outsourcing the work, as the workers in India are paid about the market wage for their work. These results and other observations lead to the conclusion that diaspora connections continue to be important even as online platforms provide many of the features that diaspora networks historically provided (e.g., information about potential workers, monitoring, and reputation foundations).

  12. Local Industrial Structures and Female Entrepreneurship in India

    Ejaz Ghani, William R. Kerr and Stephen O'Connell

    We analyze the spatial determinants of female entrepreneurship in India in the manufacturing and services sectors. We focus on the presence of incumbent female-owned businesses and their role in promoting higher subsequent female entrepreneurship relative to male entrepreneurship. We find evidence of agglomeration economies in both sectors, where higher female ownership among incumbent businesses within a district-industry predicts a greater share of subsequent entrepreneurs will be female. Moreover, higher female ownership of local businesses in related industries (e.g., those sharing similar labor needs, industries related via input-output markets) predict greater relative female entry rates even after controlling for the focal district-industry's conditions. The core patterns hold when using local industrial conditions in 1994 to instrument for incumbent conditions in 2000–2005. The results highlight that the traits of business owners in incumbent industrial structures influence the types of entrepreneurs supported.

  13. Labor Regulations and European Venture Capital

    Ant Bozkaya and William R. Kerr

    European nations substitute between employment protection regulations and labor market expenditures (e.g., unemployment insurance benefits) for providing worker insurance. Employment regulations more directly tax firms making frequent labor adjustments than other labor market insurance mechanisms. Venture capital investors are especially sensitive to these labor adjustment costs. Nations favoring labor market expenditures as the mechanism for providing worker insurance developed stronger venture capital markets over 1990–2008, especially in high volatility sectors. In this context, policy mechanisms are more important than the overall level of worker insurance.

  14. Immigration and Employer Transitions for STEM Workers

    Sari Pekkala Kerr and William R. Kerr

    We analyze the career trajectories of STEM workers and firm-level hiring of immigrants using the Longitudinal Employer-Household Dynamics (LEHD) database of the US Census Bureau. We find STEM career adjustments during periods of abnormally high immigration into the firm to be more difficult on several dimensions compared to non-STEM workers. Most notably, STEM workers do not acquire a new job as quickly as non-STEM workers; moreover, their earnings are reduced after the job transition occurs. This latter earnings effect is strongest for the first five years after the transition, abating somewhat by the tenth year.

  15. Ethnic Innovation and U.S. Multinational Firm Activity

    C. Fritz Foley and William R. Kerr

    This paper studies the impact that immigrant innovators have on the global activities of U.S. firms by analyzing detailed data on patent applications and on the operations of the foreign affiliates of U.S. multinational firms. The results indicate that increases in the share of a firm's innovation performed by inventors of a particular ethnicity are associated with increases in the share of that firm's affiliate activity in their native countries. Ethnic innovators also appear to facilitate the disintegration of innovative activity across borders and to allow U.S. multinationals to form new affiliates abroad without the support of local joint venture partners. Thus, this paper points out that immigration can enhance the competitiveness of multinational firms.

  16. From Russia with Love: The Impact of Relocated Firms on Incumbent Survival

    Oliver Falck, Christina Guenther, Stephan Heblich and William R. Kerr

    We identify the impact of local firm concentration on incumbent performance with a quasi-natural experiment. When Germany was divided after World War II, many firms in the machine tool industry fled the Soviet occupied zone to prevent expropriation. We show that the regional location decisions of these firms upon moving to western Germany were driven by non-economic factors and heuristics rather than existing industrial conditions. Relocating firms increased the likelihood of incumbent failure in destination regions, a pattern that differs sharply from new entrants. We further provide evidence that these effects are due to increased competition for local resources.

  17. The Consequences of Entrepreneurial Finance: Evidence from Angel Financings

    William R. Kerr, Josh Lerner and Antoinette Schoar

    This paper documents that ventures that are funded by two successful angel groups experience superior outcomes to rejected ventures: they have improved survival, exits, employment, patenting, web traffic, and financing. We use strong discontinuities in angel funding behavior over small changes in their collective interest levels to implement a regression discontinuity approach. We confirm the positive effects for venture operations, with qualitative support for a higher likelihood of successful exits. On the other hand, there is no difference in access to additional financing around the discontinuity. This might suggest that financing is not a central input of angel groups.

  18. Economic Impacts of Immigration: A Survey

    Sari Pekkala Kerr and William R. Kerr

    This paper surveys recent empirical studies on the economic impacts of immigration. 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 into host-country labor markets and concomitant effects for natives. The paper then turns to immigration's impact for the public finances of host countries. The final section considers emerging topics in the study of immigration. The survey particularly emphasizes the recent experiences of Northern Europe and Scandinavia and relevant lessons from traditional destination countries like the U.S.

  19. The Supply Side of Innovation: H-1B Visa Reforms and U.S. Ethnic Invention

    William R. Kerr and William F. Lincoln

    This study evaluates the impact of high-skilled immigrants on U.S. technology formation. We use reduced-form specifications that exploit large changes in the H-1B visa program. Higher H-1B admissions increase immigrant science and engineering (SE) employment and patenting by inventors with Indian and Chinese names in cities and firms dependent upon the program relative to their peers. Most specifications find limited effects for native SE employment or patenting. We are able to rule out displacement effects, and small crowding-in effects may exist. Total SE employment and invention increases with higher admissions primarily through direct contributions of immigrants.

  20. What Causes Industry Agglomeration? Evidence from Coagglomeration Patterns

    Glenn Ellison, Edward Glaeser and William R. Kerr

    Why do firms cluster near one another? We test Marshall's theories of industrial agglomeration by examining which industries locate near one another, or coagglomerate. We construct pairwise coagglomeration indices for US manufacturing industries from the Economic Census. We then relate coagglomeration levels to the degree to which industry pairs share goods, labor, or ideas. To reduce reverse causality, where collocation drives input-output linkages or hiring patterns, we use data from UK industries and from US areas where the two industries are not collocated. All three of Marshall's theories of agglomeration are supported, with input-output linkages particularly important.

  21. Banking Deregulations, Financing Constraints and Firm Entry Size

    William R. Kerr and Ramana Nanda

    We examine the effect of US branch banking deregulations on the entry size of new firms using micro-data from the US Census Bureau. We find that the average entry size for startups did not change following the deregulations. However, among firms that survived at least four years, a greater proportion of firms entered either at their maximum size or closer to the maximum size in the first year. The magnitude of these effects were small compared to the much larger changes in entry rates of small firms following the reforms. Our results highlight that this large-scale entry at the extensive margin can obscure the more subtle intensive margin effects of changes in financing constraints.

  22. Breakthrough Inventions and Migrating Clusters of Innovation

    William R. Kerr

    We investigate the speed at which clusters of invention for a technology migrate spatially following breakthrough inventions. We identify breakthrough inventions as the top one percent of U.S. inventions for a technology during 1975-1984 in terms of subsequent citations. Patenting growth is significantly higher in cities and technologies where breakthrough inventions occur after 1984 relative to peer locations that do not experience breakthrough inventions. This growth differential in turn depends on the mobility of the technology's labor force, which we model through the extent that technologies depend upon immigrant scientists and engineers. Spatial adjustments are faster for technologies that depend heavily on immigrant inventors. The results qualitatively confirm the mechanism of industry migration proposed in models like Duranton (2007).

  23. Clusters of Entrepreneurship

    Edward L. Glaeser, William R. Kerr and Giacomo A.M. Ponzetto

    Employment growth is strongly predicted by smaller average establishment size, both across cities and across industries within cities, but there is little consensus on why this relationship exists. Traditional economic explanations emphasize factors that reduce entry costs or raise entrepreneurial returns, thereby increasing net returns and attracting entrepreneurs. A second class of theories hypothesizes that some places are endowed with a greater supply of entrepreneurship. Evidence on sales per worker does not support the higher returns for entrepreneurship rationale. Our evidence suggests that entrepreneurship is higher when fixed costs are lower and when there are more entrepreneurial people.

  24. Democratizing Entry: Banking Deregulations, Financing Constraints, and Entrepreneurship

    William R. Kerr and Ramana Nanda

    We examine entrepreneurship and creative destruction following US banking deregulations using Census Bureau data. US banking reforms brought about exceptional growth in both entrepreneurship and business closures. Most of the closures, however, were the new ventures themselves. Although we do find evidence for the standard story of creative destruction, the most pronounced impact was a massive increase in churning among new entrants. We argue that creative destruction requires many business failures along with the few great successes. The successes are very difficult to identify ex ante, which is why democratizing entry is an important trait of well-functioning capital markets.

  25. Local Industrial Conditions and Entrepreneurship: How Much of the Spatial Distribution Can We Explain?

    Edward L. Glaeser and William R. Kerr

    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.

  26. Ethnic Scientific Communities and International Technology Diffusion

    William R. Kerr

    This study explores the importance of knowledge transfer for international technology diffusion by examining ethnic scientific and entrepreneurial communities in the US and their ties to their home countries. US ethnic research communities are quantified by applying an ethnic-name database to individual patent records. International patent citations confirm knowledge diffuses through ethnic networks, and manufacturing output in foreign countries increases with an elasticity of 0.1-0.3 to stronger scientific integration with the US frontier. To address reverse-causality concerns, reduced-form specifications exploit exogenous changes in US immigration quotas. Consistent with a model of sector reallocation, output growth in less developed economies is facilitated by employment gains, while more advanced economies experience sharper increases in labor productivity. The ethnic transfer mechanism is especially strong in high-tech industries and among Chinese economies. The findings suggest channels for transferring codified and tacit knowledge partly shape the effective technology frontiers of developing and emerging economies.

  27. The Survey of Industrial R&D--Patent Database Link Project

    William R. Kerr and Shihe Fu

    This paper details the construction of a firm-year panel dataset combining the NBER Patent Dataset with the Survey of Industrial R&D conducted by the Census Bureau and National Science Foundation. The dataset constitutes a platform that offers an unprecedented view of the R&D-to-patenting innovation process and a close analysis of the strengths and limitations of the R&D survey. The files are linked through a name-matching algorithm customized for uniting the firm names to which patents are assigned with the firm names in the Census Bureau's SSEL business registry. Through the Census Bureau's file structure, R&D can be linked to the operating performances of each firm's establishments, further facilitating innovation-to-productivity studies.

  28. Entrepreneurship and Urban Success: Toward a Policy Consensus

    Zoltan J. Acs, Edward L. Glaeser, Robert E. Litan, Lee Fleming, Stephan J. Goetz, William R. Kerr, Steven Klepper, Stuart S. Rosenthal, Olav Sorenson and William C. Strange

    Like all politics, all entrepreneurship is local. Individuals launch firms and, if successful, expand their enterprises to other locations. But new firms must start somewhere, even if their businesses are conducted largely or exclusively on the Internet. Likewise, policymakers at local and state levels increasingly recognize that entrepreneurship is the key to building and sustaining their economies' growth. Although this is a seemingly obvious proposition, it represents something of a departure from past thinking about how local, state, or regional economies grow. Historically, state and local policymakers have put their energies into trying to attract existing firms from somewhere else, either to relocate to a particular area or to build new facilities there. Such smokestack chasing - or, in this cleaner era, simply firm chasing - often has degenerated into what is essentially a zero-sum game for the national economy. When one city or state offers tax breaks or other financial inducements to encourage firms to locate new plants or headquarters, and succeeds, some other city or state loses out in the process. Local, state, and regional economic development centered on entrepreneurship, however, is a fundamentally different phenomenon. The formation and growth of new firms, especially those built around new products or ways of doing things, wherever this occurs, is clearly a positive sum game, not just for the locality, but for the nation as a whole. This essay provides a guide to policymakers and citizens to what is known about the effects of various local and state policies aimed at fostering entrepreneurially driven growth. There is also much we do not know; thus, the essay identifies subjects that require further research.

  29. Does Employment Protection Reduce Productivity? Evidence from U.S. States

    David H Autor, William R. Kerr and Adriana D. Kugler

    Theory predicts that mandated employment protections may reduce productivity by distorting production choices. Firms facing (non-Coasean) worker dismissal costs will curtail hiring below efficient levels and retain unproductive workers, both of which should affect productivity. These theoretical predictions have rarely been tested. We use the adoption of wrongful-discharge protections by U.S. state courts over the last three decades to evaluate the link between dismissal costs and productivity. Drawing on establishment-level data from the Annual Survey of Manufacturers and the Longitudinal Business Database, our estimates suggest that wrongful-discharge protections reduce employment flows and firm entry rates. Moreover, analysis of plant-level data provides evidence of capital deepening and a decline in total factor productivity following the introduction of wrongful-discharge protections. This last result is potentially quite important, suggesting that mandated employment protections reduce productive efficiency as theory would suggest. However, our analysis also presents some puzzles including, most significantly, evidence of strong employment growth following adoption of dismissal protections. In light of these puzzles, we read our findings as suggestive but tentative.

  30. Limits on Interest Rate Rules in the IS Model

    William R. Kerr and Robert G. King

    There has been a substantial amount of research on interest rate rules. This literature finds that the feasibility and desirability of interest rate rules depends on the structure of the model used to approximate macroeconomic reality. We employ a series of macroeconomic models to shed light on how aspects of model structure influence the limits on interest rate rules. In particular, we show that a simple respecification of the IS schedule, which we call the expectational IS schedule, makes the textbook model generate the same limits on interest rate rules as the fully articulated models. We then use this simple model to study the design of interest rate rules with nominal anchors. If the monetary authority adjusts the interest rate in response to deviations of the price level from a target path, then there is a unique equilibrium under a wide range of parameter choices: all that is required is that the authority raise the nominal rate when the price level is above the target path and lower it when the price level is below the target path. By contrast, if the monetary authority responds to deviations of the inflation rate from a target path, then a much more aggressive pattern is needed: the monetary authority must make the nominal rate rise by more than one-for-one with the inflation rate. Our results on interest rate rules with nominal anchors are preserved when we further extend the model to include the influence of expectations on aggregate supply.

  1. Firms and the Economics of Skilled Immigration

    Sari Pekkala Kerr, William R. Kerr and William Lincoln

    Firms play a central role in the selection, sponsorship, and employment of skilled immigrants entering the United States for work through programs like the H-1B visa. This role has not been widely recognized in the literature, and the data to better understand it have only recently become available. This paper discusses the evidence that has been assembled to date in understanding the impact of high-skilled immigration from the perspective of the firm and the open areas that call for more research. Since much of the U.S. immigration process for skilled workers rests in the hands of employer firms, a stronger understanding of these implications is essential for future policy analysis, particularly for issues relating to fostering innovation.

  2. Agglomeration and Innovation

    Gerald Carlino and William R. Kerr

    This chapter reviews academic research on the connections between agglomeration and innovation. We first describe the conceptual distinctions between invention and innovation. We then describe how these factors are frequently measured in the data and some resulting empirical regularities. Innovative activity tends to be more concentrated than industrial activity, and we discuss important findings from the literature about why this is so. We highlight the traits of cities (e.g., size, industrial diversity) that theoretical and empirical work link to innovation, and we discuss factors that help sustain these features (e.g., the localization of entrepreneurial finance).

    Aaron Chatterji, Edward Glaeser and William R. Kerr

    This chapter reviews recent academic work on the spatial concentration of entrepreneurship and innovation in the United States. We discuss rationales for the agglomeration of these activities and the economic consequences of clusters. We identify and discuss policies that are being pursued in the United States to encourage local entrepreneurship and innovation. While arguments exist for and against policy support of entrepreneurial clusters, our understanding of what works and how it works is quite limited. The best path forward involves extensive experimentation and careful evaluation.

  4. Financing Constraints and Entrepreneurship

    William R. Kerr and Ramana Nanda

    Financing constraints are one of the biggest concerns impacting potential entrepreneurs around the world. Given the important role that entrepreneurship is believed to play in the process of economic growth, alleviating financing constraints for would-be entrepreneurs is also an important goal for policymakers worldwide. We review two major streams of research examining the relevance of financing constraints for entrepreneurship. We then introduce a framework that provides a unified perspective on these research streams, thereby highlighting some important areas for future research and policy analysis in entrepreneurial finance.

  6. The Agglomeration of U.S. Ethnic Inventors

    William R. Kerr

    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).

    Rebeca Minguela hopes to create an arbitrage platform, similar to Rocket Internet, that can bring start-up ideas and opportunities to Spain. However, Blink Booking, her first venture and proof of concept, is rocked by a co-founder's breach of confidence and departure. Minguela must repair the damage to Blink's management team, restore investor confidence, and continue Blink's rapid growth to deliver on the venture's initial promise. The case explores management team roles, equity splits, and related entrepreneurial challenges that Minguela must navigate. Minguela must also decide whether her long-term goal of an incubator-like platform for Spain is really feasible. The case describes how her vision differs from Rocket Internet—a large German incubator that also provides its entrepreneurs with ready-made business models from existing companies—allowing students to compare the models and discuss the ethics of cloning.

  8. EverTrue: Mobile Technology Development (A)

    William R. Kerr and Alexis Brownell

    Brent Grinna is evaluating different options for the technology development of his start-up's iPhone app, including hiring local programmers, finding a CTO, or outsourcing. He only has a little over two months before he presents his alumni networking app to Brown University, in the hope that they will adopt it and fund his company, EverTrue. He lacks the technical knowledge necessary to make the prototype himself, and so has to quickly decide on the best option. He is considering multiple ways to find a developer, including hiring a local programmer or making use of a local app-development company; using an outsourcing platform like oDesk; contracting with Dashfire, a friend's company that charges low fees for product development in exchange for equity; or finding and hiring a CTO or technical co-founder. Grinna must weigh issues like cost, speed of development, equity retention, proximity and ease of collaboration, and control of intellectual property. The case further provides an opportunity for discussing the business models of global firms like oDesk and Dashfire.

Since the end of the events of the A case, Grinna's company, EverTrue, has launched the app, found an advisor and office space, and been covered in the Boston Globe. He is still unsure about how to move forward with EverTrue, and is struggling with issues like a conflict in his B2B2C business models or what his next steps should be, as well as personal concerns. At the moment, he is trying to decide between three candidates for CTO, and he must weigh the importance of having an MBA and having experience in app development, and also must consider how hiring a CTO will affect his relationship with Dashfire.

  11. Home Essentials: Building a Global Service Business with Local Operations

    Lynda M. Applegate, William R. Kerr and David Lane

    Chris Exline founded Home Essentials, a furniture rental business targeted toward expatriates, in Singapore but rapidly moved the base of operations to Hong Kong. The company was highly successful in Singapore and Hong Kong and then pursued rapid global expansion. Lacking frameworks for deciding upon countries to enter and services to deliver in each country, Exline used gut instinct. Lacking control systems and information, he failed to identify problems early and had trouble understanding the root cause of failures. The global financial crisis intensified the problems. The case ends by describing how Exline was able to turn around the troubled company and develop necessary governance systems. The question of whether to once more attempt to grow beyond Hong Kong and, if so, the approach to take in selecting countries, is a central issue Exline faced at the time of the case.

  23. ReSource Pro

    Lynda M. Applegate, William R. Kerr, Elisabeth Koll and David Lane

    Matt Bruno, founder and general manager of ReSource Pro, left his job working for a New York City-based insurance program shortly after the World Trade Center bombing and arrived in China. Initially he planned to teach English, but soon the entrepreneurial spirit of the country caused him to begin exploring opportunities. He returned to New York and talked his former boss into allowing him to start a back-office services firm for their insurance company clients, which grew into ReSource Pro. By year-end 2007, ReSource Pro employed 250 people, of whom only 4 were U.S.-based. With aggressive growth plans, Bruno began examining potential cities in China for expansion. After narrowing his list of potential expansion sites to the five Chinese cities of Chengdu (the capital of Sichuan Province), Jinan (capital of Shandong Province), Nanjing (capital of Jiangsu Province), Suzhou (Jiangsu), and Wuhan (capital of Hubei Province), he now had to make a final choice.

    by William R. Kerr

    Starting up a new venture amid rapid change is fraught with challenges. Whether you are starting a new business, launching a new business line, or building an entrepreneurial culture within a small-to-midsize company, this program provides a new perspective and core skills that you can immediately put to use. Topics include—identifying and analyzing entrepreneurial opportunities; turning a viable opportunity into a focused strategy and well-defined business initiative; developing an effective business plan; creating "pitches" to sell the idea to investors, customers, partners, and key employees; attracting the top talent and vital resources required to turn a vision into reality; building the organization and capabilities needed to launch and nurture early-stage ventures; evolving the strategy, organization, and leadership model as the business grows; and recognizing and managing risk, while creating and measuring value.

  2. Launching Global Ventures (MBA Education—Elective Curriculum)

    by William R. Kerr

    Globalization and technological advances have forever changed the landscape of high-growth ventures. High-impact entrepreneurship is worldwide, and many ventures launch today with a presence in multiple countries from Day One. Launching Global Ventures (LGV) first explores the business models behind global ventures (e.g., Rocket Internet, Skype), identifying which critical elements of the business are being globalized and assessing how well ventures are harnessing globalization into their strategic core. LGV then considers the managerial challenges that global ventures encounter (e.g., distributed teams), how to conduct effective location choice decisions, the optimal design of cross-border partnerships, etc. The course brings together these two sides to identify why global ventures encounter difficulties scaling and what managers must do to break through the intermediate barriers and become exceptional global businesses.
  3. The Entrepreneurial Manager (MBA Education—Required Curriculum)

    by William R. Kerr

    Entrepreneurial managers transform opportunities into companies and institutions that make a difference in the world. In their successful “pursuit of opportunity without regard to resources currently controlled,” they make decisions under conditions of profound uncertainty and do so while balancing great risks against potentially attractive rewards. Moreover, they operate without the benefit of well-defined processes for making such choices and with few resources. As a consequence, entrepreneurial companies offer an ideal platform for understanding the challenges facing a general manager. Building on the foundation laid by other RC courses, The Entrepreneurial Manager (TEM) provides students with an understanding of issues facing entrepreneurs and an exposure to the skills involved in addressing them. TEM explores how executives should approach making critical decisions during the different phases of an entrepreneurial company's life. (http://www.hbs.edu/faculty/units/em/Pages/curriculum.aspx)
  4. Theoretical and Empirical Perspectives on Entrepreneurship (Doctoral Education)

    by William R. Kerr

    TEPE explores scholarly work from economics and finance disciplines regarding entrepreneurship--the formation and growth of new firms. While work on this topic dates back to Schumpeter and earlier, academic research regarding entrepreneurship has exploded over the last decade. Reflecting the complex nature of the entrepreneurship, TEPE touches on multiple academic disciplines and research methodologies. There are now two complementary doctoral classes, each taught every other year, with the Spring 2015 course focusing on topics related to corporate finance, including entrepreneurial finance and behavioral economics. The 2016 course will focus on entrepreneurship and its relationship to other disciplines in economics, such as its link to industrial organization, organizational economics, and economic growth. Offered jointly with the Faculty of Arts and Sciences as Economics 2726. (http://www.people.hbs.edu/wkerr/TEPE.pdf)
