Screening requirements are common features of fraud and corruption mitigation efforts around the world. Yet imposing these requirements involves trade-offs between higher administrative costs, delayed benefits, and exclusion of genuine beneficiaries on one hand and lower fraud on the other. We...

New technologies allow perfect detection of environmental violations at near-zero marginal cost, but take-up is low. We conducted a field experiment to evaluate enforcement of water conservation rules with smart meters in Fresno, CA. Households were randomly assigned combinations of enforcement...

We examine how changes in the salience of workplace risk affect police behavior and public safety. Specifically, we investigate cases of police officer deaths while on duty. Officers respond to a peer death by decreasing arrest activity for one to two months, consistent with heightened fear....

This paper studies the impact of adult prosecution on recidivism and employment trajectories for adolescent, first-time felony defendants. We use extensive linked Criminal Justice Admin- istrative Record System and socio-economic data from Wayne County, Michigan (Detroit). Using the discrete age...

How does immigration enforcement affect public safety? Heightened enforcement could reduce crime by deterring and incapacitating immigrant offenders or, alternatively, increase crime by discouraging victims from reporting offenses. We study the U.S. Secure Communities program, which expanded...

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 study how public sector workers balance their professional motivations with private economic concerns, focusing on police arrests. Arrests made near the end of an officer's shift typically require overtime work, and officers respond by reducing arrest frequency but increasing arrest quality....

The rise of shale gas and tight oil development has triggered a major debate about hydraulic fracturing (HF). In an effort to mitigate risks from HF, especially with respect to water quality, many U.S. states have introduced disclosure mandates for HF wells and fracturing fluids. We use this...

This article surveys the theory of the public enforcement of law -- the use of public agents (inspectors, tax auditors, police, prosecutors) to detect and to sanction violators of legal rules. We first present the basic elements of the theory, focusing on the probability of imposition of...
