AbstractWe 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 legitim…
AbstractAn 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 …
AbstractWe 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 preregis…
AbstractWe use data from the Veterans Administration to examine the efficacy of primary care providers (PCPs). Leveraging quasi-random assignment of veterans to PCPs, we measure effectiveness using ambulatory care sensitive conditions (ACSC) and hospit…
AbstractUsing rapid expansion of the Beijing subway from 2000 to 2018, we analyze its impact on collaborative matches in innovations. We find that an hour reduction in travel time between a pair of locations in Beijing brought 14.85% to 37.69% increase…
AbstractThis 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 …
