Where the state is weak, traditional authorities often control the local provision of land, justice, and public goods. These authorities are criticized for ruling in an undemocratic and unaccountable fashion, and are typically quite…

This study examines how an increase in tick size affects algorithmic trading (AT), fundamental information acquisition (FIA), and the price discovery process around earnings announcements (EAs). Leveraging the SEC’s randomized “Tick Size Pilot”…

Using a large sample of business groups from more than 100 countries around the world, we show that group information matters for parent and subsidiary default prediction. Group firms may support each other when in financial distress. Potential…

While polls show progressive economic policies are popular, progressive candidates typically lose elections in the U.S. One explanation for this progressive paradox is that the opponents of progressive candidates often win through “symbolic…

We explore spatial price discrimination in the context of a ride-sharing platform that serves a network of locations. Riders are heterogeneous in terms of their destination preferences and their willingness to pay for receiving service. Drivers…

Facing imminent disruption, many large, established firms have embraced innovation as a way to develop new growth businesses. To succeed in the face of disruptive change requires established firms to master three distinct disciplines: ideation,…

Concerns about the dissemination of spurious results have led to calls for pre-analysis plans (PAPs) to avoid ex-post “p-hacking.” But often the conceptual hypotheses being tested do not imply the level of specificity required for a PAP. In this…

Motivated by drug design, we consider the best-arm identification problem in generalized linear bandits. More specifically, we assume each arm has a vector of covariates, there is an unknown vector…

Women continue to be underrepresented in STEM (science, technology, engineering, math) fields. As such, there has been an increased interest in interventions to reduce bias against, and increase inclusion of, women in STEM. In this…

Blockchain technology provides decentralized consensus and potentially enlarges the contracting space through smart contracts. Meanwhile, generating decentralized consensus entails distributing information that necessarily alters the…

We study the dynamic mechanism design problem of a seller who repeatedly auctions independent items over a discrete time horizon to buyers who face a cumulative budget constraint. A driving motivation behind our model is the emergence of real-…

In many prediction problems researchers have found that combinations of prediction methods (“ensembles”) perform better than individual methods. In this paper we apply these ideas to synthetic control type problems in panel data. Here a number of…

BACKGROUND: Care coordination is crucial to avoid potential risks of care fragmentation in people with complex care needs. While there are many empirical and conceptual approaches to measuring and improving care coordination, use of theory is…

Why do some firms adopt certain tax havens, and how sensitive is the demand for tax havens? We address these questions by studying how the repeal of section 936 tax credits affected firms with affiliates in Puerto Rico. We first describe the…

This perspective paper seeks to lay out an efficient approach for health care providers, researchers, and other stakeholders involved in interventions aimed at improving care coordination to partner in locating and using applicable care…

Blockchain technology has real potential to provide business value. While many technical, financial, and regulatory hurdles still remain, blockchain offers significant opportunity for innovation along the value chain. 

The level of journalistic resources dedicated to coverage of local politics is in a long-term decline in the US news media, with readership shifting to national outlets. We investigate whether this trend is demand- or supply-driven, exploiting a…

As the workforce ages, how will the work lives of older people evolve? One way to ease into retirement is to move to the gig economy where workers choose hours and intensity of work that fit their needs and capabilities. However, older workers…

The increasing popularity of regression discontinuity methods for causal inference in observational studies has led to a proliferation of different estimating strategies, most of which involve first fitting nonparametric regression models on both…
