We introduce new measurement tools to understand the sources of earnings differences across space. Based on the natural language employers use in job vacancy text, we develop granular measures of job tasks and of worker specialization. We find that jobs in larger commuting zones involve greater...

Urban crime rates in the United States fell markedly during the 1990s and remain at historically low levels. The statistical evidence presented here indicates that that decline, like the crime surge that preceded it, has been largely uncorrelated with changes in socioeconomic conditions across...

In the context of interwar Poland, we find that Jews tended to be more literate than non Jews, but show that this finding is driven by a composition effect. In particular, most Jews lived in cities and most non-Jews lived in rural areas, and people in cities were more educated than people in...

The charter school movement encompasses many school models. In Massachusetts in the 2010's, the site of our study, urban charter schools primarily used "No Excuses" practices, whereas nonurban charters had greater model variety. Using randomized admissions lotteries, we estimate the impact of...

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...

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...

The standard economic model of police stops implies that the contraband hit rate should rise when the number of stops or searches per officer falls, ceteris paribus. We provide empirical corroboration of such optimizing models of police behavior by examining changes in stops and frisks around...

Do investors anticipate that demands for racial equity will impact companies? We explore this question in the context of the Black Lives Matter (BLM) movement--the largest racially motivated protest movement in U.S. history--and its effect on the U.S. policing industry using a novel dataset on...
