    American Business History: A Very Short Introduction

    By: Walter Friedman

    By the early twentieth century, it became common to describe the United States as a "business civilization." President Coolidge in 1925 said, "The chief business of the American people is business." More recently, historian Sven Beckert characterized Henry Ford's massive manufactory as the embodiment of America: "While Athens had its Parthenon and Rome its Colosseum, the United States had its River Rouge Factory in Detroit..." How did business come to assume such power and cultural centrality in America?

    Turbulence, Firm Decentralization and Growth in Bad Times

    By: Philippe Aghion, Nicholas Bloom, Brian Lucking, Raffaella Sadun and John Van Reenen

    What is the optimal form of firm organization during “bad times”? We present a model of delegation within the firm to show that the effect is ambiguous. The greater turbulence following macro shocks may benefit decentralized firms because the value of local information increases (the “localist” view). On the other hand, the need to make tough decisions may favor centralized firms (the “centralist” view). Using two large micro datasets on firm decentralization from ten OECD countries and U.S. administrative data, we find that firms that delegated more power from the Central Headquarters to local plant managers prior to the Great Recession outperformed their centralized counterparts in sectors that were hardest hit by the subsequent crisis.

    JOANN: Joannalytics Inventory Allocation Tool

    By: Kris Ferreira and Srikanth Jagabathula

    Michael Joyce, Vice President of Inventory Management at JOANN, championed an effort to develop and implement an inventory allocation analytics tool that used advanced analytics to predict in-season demand of seasonal items for each of JOANN’s nearly 900 stores and optimize store-specific inventory allocation decisions guided by these predictions. After the analytics tool had been in use for a full season of products, Joyce was surprised to hear that not everyone was pleased with its outcomes. With all of the concerns raised, should Joyce halt the use of the analytics tool for the next season?

    The Tulsa Massacre and the Call for Reparations

    By: Mihir A. Desai, Suzanne Antoniou and Leanne Fan

    How should historic social injustices be addressed? Survivors of the 1921 Tulsa Massacre and their descendants believe they should be addressed through reparations and have consequently continued to push the government of Tulsa to pay reparations for the massacre. In 2020, after no direct reparations and largely symbolic governmental efforts, Representative Regina Goodwin of Tulsa, the descendant of massacre survivors, wondered if that call would finally be answered.

    Surviving Venezuela's Hyperinflation: Automercados Plaza's

    By: Alberto Cavallo, Mariana Cal and Carla Larangeira

    Under the rule of presidents Hugo Chávez and Nicolas Maduro, Venezuela experienced one of the worst economic and political meltdowns in modern history, culminating with a massive hyperinflation. Remarkably, during this dramatic times Automercados Plaza's had grown to become one of the most successful supermarket retailers in the country. Its management team had faced all kinds of challenges, including price indexation, price controls, scarcity and stockouts, informal competitors, and an ever-shifting set of government interventions. Showing resourcefulness and the flexibility needed to quickly adapt, Plaza’s had managed to survive and even thrive. The future, however, looked very uncertain.

    Biased Sampling of Early Users and the Direction of Startup Innovation

    By: Ruiqing Cao, Rembrand Koning, and Ramana Nanda

    New ventures catering to female customers should be aware that the underrepresentation of women among early users on digital platforms can reduce the venture’s growth and chances of survival. As a result of gaining fewer early users, these ventures reduce future product development and are less likely to raise VC funding.

    The Value of Descriptive Analytics: Evidence from Online Retailers

    By: Ron Berman and Ayelet Israeli

    Does the adoption of descriptive analytics impact online retailer performance, and if so, how? We use the synthetic control method to analyze the staggered adoption of a retail analytics dashboard by more than 1,000 e-commerce websites, and find an increase of 13–20% in average weekly revenues post-adoption. We demonstrate that only retailers that adopt and use the dashboard reap these benefits. The increase in revenue is not explained by price changes or advertising optimization. Instead, it is consistent with the addition of prospecting and personalization technologies to retailer websites.

Does Observability Amplify Sensitivity to Moral Frames? Evaluating a Reputation-Based Account of Moral Preferences

By: Valerio Capraro, Jillian J. Jordan and Ben Tappin
  • 2021 |
  • Working Paper |
  • Faculty Research
A growing body of work suggests that people are sensitive to moral framing in economic games involving prosociality, suggesting that people hold moral preferences for doing the “right thing”. What gives rise to these preferences? Here, we evaluate the explanatory power of a reputation-based account, which proposes that people respond to moral frames because they are motivated to look good in the eyes of others. Across four pre-registered experiments (total N = 9,601), we investigated whether reputational incentives amplify sensitivity to framing effects. Studies 1-3 manipulated (i) whether moral or neutral framing was used to describe a Trade-Off Game (in which participants chose between prioritizing equality or efficiency) and (ii) whether Trade-Off Game choices were observable to a social partner in a subsequent Trust Game. These studies found that observability does not significantly amplify sensitivity to moral framing. Study 4 ruled out the alternative explanation that the observability manipulation from Studies 1-3 is too weak to influence behavior. In Study 4, the same observability manipulation did significantly amplify sensitivity to normative information (about what others see as moral in the Trade-Off Game). Together, these results suggest that moral frames may tap into moral preferences that are relatively deeply internalized, such that the power of moral frames is not strongly enhanced by making the morally-framed behavior observable to others.

The Impact of the General Data Protection Regulation on Internet Interconnection

By: Ran Zhuo, Bradley Huffaker, KC Claffy and Shane Greenstein
  • March 2021 |
  • Article |
  • Telecommunications Policy
The Internet comprises thousands of independently operated networks, where bilaterally negotiated interconnection agreements determine the flow of data between networks. The European Union’s General Data Protection Regulation (GDPR) imposes strict restrictions on processing and sharing of personal data of EU residents. Both contemporary news reports and simple bilateral bargaining theory predict reduction in data usage at the application layer and would negatively impact incentives for negotiating interconnection agreements at the internet layer due to reduced bargaining power of European networks and increased bargaining frictions. Considerable empirical evidence at the application layer confirms this prediction. Using a large sample of interconnection agreements between networks around the world in 2015–2019, we empirically investigate the impact of the GDPR on interconnection behavior of network operators in the European Economic Area (EEA) compared to network operators in non-EEA OECD countries. All evidence estimates precisely zero effects across multiple measures: the number of observed agreements per network, the inferred agreement types, and the number of observed IP-address-level interconnection points per agreement. We also find economically small effects of the GDPR on the entry and the observed number of network customers. We conclude that the short-run costs for GDPR are concentrated at the application layer.

Do Household Wealth Shocks Affect Productivity? Evidence from Innovative Workers During the Great Recession

By: S. Bernstein, T. McQuade and R. Townsend
  • February 2021 |
  • Article |
  • Journal of Finance
We investigate how the deterioration of household balance sheets affects worker productivity, and, in turn, economic downturns. Specifically, we compare the output of innovative workers who experienced differential declines in housing wealth during the financial crisis but were employed at the same firm and lived in the same metropolitan area. We find that, following a negative wealth shock, innovative workers become less productive and generate lower economic value for their firms. The reduction in innovative output is not driven by workers switching to less innovative firms or positions. These effects are more pronounced among workers at greater risk of financial distress.

Platform Diffusion at Temporary Gatherings: Social Coordination and Ecosystem Emergence

By: Tommy Pan Fang, Andy Wu and David R. Clough
  • February 2021 |
  • Article |
  • Strategic Management Journal
Software platforms create value by cultivating an ecosystem of complementary products and services. Existing explanations for how a prospective complementor chooses platforms to join assume the complementor has rich information about the range of available platforms. However, complementors lack this information in many ecosystems, raising the question of how complementors learn about platforms in the first place. We investigate whether attending a temporary gathering—a hackathon—impacts the platform choices of software developers. Through a large-scale quantitative study of 1,302 developers and 167 hackathons, supported by qualitative research, we analyze the multiple channels—sponsorship, social learning, knowledge exchange, and social coordination—through which hackathons serve as a social forum for the diffusion of platform adoption among attendees.

Testing the Waters: Behavior across Participant Pools

By: Erik Snowberg and Leeat Yariv
  • February 2021 |
  • Article |
  • American Economic Review
We leverage a large-scale incentivized survey eliciting behaviors from (almost) an entire university student population, a representative sample of the U.S. population, and Amazon Mechanical Turk (MTurk) to address concerns about the external validity of experiments with student participants. Behavior in the student population offers bounds on behaviors in other populations, and correlations between behaviors are largely similar across samples. Furthermore, non-student samples exhibit higher measurement error. Adding historical lab participation data, we find a small set of attributes over which lab participants differ from non-lab participants. Using an additional set of lab experiments, we see no evidence of observer effects.

Health Care Measurements That Improve Patient Outcomes

By: Robert S. Kaplan, Lara Jehi, Clifford Y. Ko, Andrea Pusic and Mary Witkowski
  • February 2021 |
  • Article |
  • NEJM Catalyst Innovations in Care Delivery
This article describes the challenges and solutions in determining whether a patient’s treatment has been successful. Such an assessment depends on multiple factors, including the patient’s pretreatment status; the qualifications of personnel performing the treatment; the treating facility’s infrastructure and culture; the use of evidence-based clinical processes; the baseline incidence of treatment complications; and, most challenging, the ability to measure the outcomes that matter to patients. Recent advances in IT and the development of validated measurement instruments now enable consistent collection and analysis of metrics that capture all the relevant dimensions of a patient’s treatment. These data can be mobilized for learning that improves clinical and administrative processes, optimization of care pathways, shared decision-making, accountability, and payment contracting. Providers can now have access to the tools and technology that allow them to be transparent about and accountable for the outcomes that their patients experience.

A Dynamic Theory of Multiple Borrowing

By: Daniel Green and Ernest Liu
  • February 2021 |
  • Article |
  • Journal of Financial Economics
Multiple borrowing—a borrower obtains overlapping loans from multiple lenders—is a common phenomenon in many credit markets. We build a highly tractable, dynamic model of multiple borrowing and show that, because overlapping creditors may impose default externalities on each other, expanding financial access by introducing more lenders may severely backfire. Capital allocation is distorted away from the most productive uses. Entrepreneurs choose inefficient endeavors with low returns-to-scale. These problems are exacerbated when investments become more pledgeable or when borrowers have access to more lenders, explaining why increased access to finance does not always improve outcomes.

Variety of Innovation in Global Value Chains

By: Giulio Buciuni and Gary P. Pisano
  • Article |
  • Journal of World Business
This article analyzes how the geography and organization of pre- and production stages in Global Value Chains (GVC) contribute to lead firms' innovation development. A novel approach in GVC studies is introduced based on transaction cost economics (TCE) and the innovation strategy's Modularity-Maturity matrix. The combination of these two perspectives allowed the conceptualization and assessment of two key dimensions in the generation of innovation in GVC: the geographic dispersion of value chain stages and lead firms' control over operations. The study of the intersection of the two dimensions led to the identification of four distinct innovation models in GVC. Evidence from four global manufacturing industries—pharmaceuticals, bicycle, design furniture and wine—suggests that lead firms' innovation capabilities and product innovation cycle are shaped by the specific structure of the GVC wherein they operate.
