Abstract
This paper studies the effect of the West Philadelphia Promise Zone initiative on violent crime rates in a high-crime area of West Philadelphia, where a series of educational, public-safety, and quality-of-life improvement grants were disbursed from 2014 onward. My difference-in-differences analysis with two-way fixed effects and cluster bootstrapped standard errors provides the first causal evidence of a modest (approximately 10%) reduction in violent crime, primarily assaults, attributable to this program. By the end of 2019, violent crime in the Promise Zone descended to around the average level across Philadelphia. A synthetic difference-in-differences estimator corroborates this result, with some important caveats. In addition, I find a significant reduction in violent crime in and around schools given GEAR UP and Promise Neighborhood grants, two of the largest grants facilitated through the Promise Zone program.
