Our estimates are generally similar in magnitude to, but are estimated with a great deal more precision than, those from the quasi-experimental literature. Our estimates imply that each dollar spent on police is associated with approximately $1.60 in reduced victimization costs, suggesting that U.S. cities employ too few police. The estimates confirm a controversial finding from the previous literature that police reduce violent crime more so than property crime.
