摘要：We introduce group cohesion to study the economic relevance of social relationships in team production. We operationalize measurement of group cohesion, adapting the oneness scale from psychology. A series of experiments, including a preregistered replication, reveals strong, positive associations between group cohesion and performance assessed in weak-link coordination games, with high-cohesion groups being likely to achieve superior equilibria. In exploratory analysis, we identify beliefs ra...

摘要：Satellite-based image classification facilitates low-cost measurement of the Earth's surface composition. However, misclassified imagery can lead to misleading conclusions about transition processes. We propose a correction for transition rate estimates based on the econometric measurement error literature to extract the signal (truth) from its noisy measurement (satellite-based classifications). No ground-truth data are required in the implementation. Our proposed correction produces consiste...

摘要：Colleges can send signals about their quality by adopting new, more alluring names. We study how this affects college choice and labor market performance of college graduates. Administrative data show name-changing colleges enroll higher-aptitude students, with larger effects for alluring-but-misleading name changes and among students with less information. A large resume audit study suggests a small premium for new college names in most jobs, and a significant penalty in lower-status jobs. We...

摘要：We investigate how managers help firms grow by entering a new export market. We conduct an event study on the decision to export to Angola using data on Portuguese firms and workers. We evaluate the impact of the presence of managers with experience in exporting to the Angolan market on a firm's entry success in the aftermath of an exogenous shock: the sudden end of the Angolan civil war. We show that the presence of managers doubles the probability of a firm entering the market. We do not fin...

摘要：This article quantifies the impact of the battery electric vehicle subsidy program in China. We build a structural model of dynamic demand and Bertrand Nash supply to study price elasticity and changes in production costs. The model highlights four channels through which the subsidy program impacts the market: temporal elasticity, in response to a current price change; intertemporal elasticity, in response to a future price change; and multiplication effects through peer and learning by doing....

摘要：We investigate the role of performance feedback, in the form of a public leaderboard, in a sequential-sampling contest with costly observations. We show theoretically that for contests with a fixed ending date (i.e., finite horizon), providing public performance feedback may result in fewer expected observations and a lower expected value of the winning observation. We conduct a controlled laboratory experiment to test the theoretical predictions and find that the experimental results largely ...

摘要：We study the impact of reforms that introduced more stringent, biometric ID requirements into India's largest social protection program, using large-scale randomized and natural experiments. Corruption fell but with substantial costs to legitimate beneficiaries, 1.5-2 million of whom lost access to benefits at some point during the reforms. At the same time, adverse effects appear to have been driven primarily by decisions about the way the transition was managed, illustrating both the risks o...

摘要：An administrative rule in North Carolina allowed students who failed an exam to retake it approximately two weeks later, triggering a brief yet intense test preparation period. We develop a structural model that accounts for selection and find that these students score much higher on the retest. Using a regression discontinuity design, we find substantial fade-out of the test score gains after one year but some persistence thereafter. Unlike other interventions that produce similar initial inc...

摘要：I propose a new method of identifying firms' subjective beliefs in dynamic models. In settings where actions are continuous and substitutable in contributing to an endogenous state, I show how beliefs about exogenous state transitions can be separately identified from static payoffs. Applying this method to identifying beliefs about future SO2 allowance prices in the U.S. Acid Rain Program, I find that electric utilities underestimate the movements in the allowance price, leading to compliance...

摘要：The entry of High-Speed Railways (HSR) represents disruptive competition to airlines. Utilizing a unique dataset of all flights departing from Beijing to 113 domestic destinations in China since January 2009, we employ a difference-in-differences approach to examine the effects of HSR entry on on-time performance and to identify the channels. We document two main findings. First, the entry of HSR leads to significant reductions in the mean and variance of travel delays on the affected airline ...
