01. Does Race Matter for Police Use of Force? Evidence from 911 Calls
Claremont Graduate University
Abstract: This paper examines race and police use of force using data on 1.6 million 911 calls in two cities, neither of which allows for discretion in officer dispatch. Results indicate White officers increase force much more than minority officers when dispatched to more minority neighborhoods. Estimates indicate Black (Hispanic) civilians are 55 (75) percent more likely to experience any force, and five times as likely to experience a police shooting, compared to if White officers scaled up force similarly to minority officers. Additionally, 14 percent of White officers use excess force in Black neighborhoods relative to our statistical benchmark.
02. Targeting High Ability Entrepreneurs Using Community Information: Mechanism Design in the Field
Abstract: Identifying high-growth microentrepreneurs in low-income countries remains a challenge due to a scarcity of verifiable information. With a cash grant experiment in India we demonstrate that community knowledge can help target high-growth microentrepreneurs; while the average marginal return to capital in our sample is 9.4 percent per month, microentrepreneurs reported in the top third of the community are estimated to have marginal returns to capital between 24 percent and 30 percent per month. Further we find evidence that community members distort their predictions when they can influence the distribution of resources. Finally, we demonstrate that simple mechanisms can realign incentives for truthful reporting.
01. Measuring the Private and Social Returns to R&D: Unintended Spillovers versus Technology Markets
Accepted March 14, 2022
Abstract: The canonical approach to measuring private and social returns to R&D assumes diffusion through spillovers. We develop a general framework that allows R&D to dif- fuse both through spillovers and voluntary technology transfers.To operationalize the framework,we create a dataset of interactions in the market for technology between publicly held U.S.firms.We use changes in tax incentives for R&D to identify causal effects.Taking market channels into account decreases the observed difference between social and private returns to R&D as compared to the canonical approach.The analysis suggests significant gains from trade in markets for technology.
02. The Causal Impact of Removing Children from Abusive and Neglectful Homes
Accepted March 10, 2022
Abstract: This paper measures impacts of removing children from families investigated for abuse or neglect.We use removal tendencies of child protection investigators as an instrument.Our analysis focuses on young children investigated before age six and finds that removal significantly increases test scores and reduces grade repetition for girls.There are no detectable impacts for boys.This pattern of results does not appear to be driven by heterogeneity in pre-removal characteristics,foster placements,or types of schools attended after removal.The results are consistent with the hypothesis that development of abused and neglected girls is more responsive to home removal.
