Given police abolitionism's new visibility after the 2020 racial justice protests, we assess stakeholder beliefs on the protests' stock impacts on police-affiliated firms. Experts generally underestimate the firms' stock gains, except situated experts like community organizers and police...

What causes adverse policing outcomes, such as excessive uses of force and unnecessary arrests? Prevailing explanations focus on problematic officers or deficient regulations and oversight. Here, we introduce a new, overlooked perspective. We suggest that the cognitive demands inherent in...

We study the implications of police discretion for public safety. Highway patrol officers exercise discretion over fines by deviating from statutory fine rules. Relying on variation across officers in this discretionary behavior, we find that harsher sanctions reduce future traffic offending and...

We conducted a randomized controlled trial to evaluate the impact of an innovative police patrol program on sexual harassment in public spaces in Hyderabad, India. In collaboration with the Hyderabad City Police, we randomized both exposure to police patrols and the visibility of officers by...

Given the use of an individual's arrest history for many economic and social outcomes, reducing conviction-less arrests (arrests that result in no charges or where the defendant is found not guilty) is an important policy goal. This paper examines which officers are making conviction-less...

We propose a simple model of trooper behavior to design empirical tests for whether troopers of different races are monolithic in their search behavior, and whether they exhibit relative racial prejudice in motor vehicle searches. Our test of relative racial prejudice provides a partial solution...

Recent theoretical models based on dynamic human capital formation, or social influence, suggest an inverse relationship between criminal activity and economic opportunity and between criminal activity and deterrence, but predict an asymmetric response of crime. In this paper we use three...

This paper provides new evidence on the role of preference-based versus statistical discrimination in racial profiling using a unique data set that includes the race of both the driver and the officer. We first generalize the model presented in Knowles, Persico and Todd (2001) and show that the...

In order to encourage anti-drug policing, both the federal government and many state governments have enacted laws that allow police agencies to keep a substantial fraction of assets that they seize in drug arrests. By adjusting their own allocations to police budgets, however, county...

This paper examines potential tradeoffs between research methods in answering important questions versus providing more cleanly identified estimates on problems that are potentially of lesser interest. The strengths and limitations of experimental and quasi-experimental methods are discussed and...
