This paper estimates the marginal accident externality of driving in Central London by exploiting variation in traffic flow induced by the London Congestion Charge Zone using an instrumental variable approach. The charge attributed to a 9.4% reduction in traffic flow, which resulted in a less...

In this study, we estimate the cost of gun crime using a revealed preference framework by relying on an institutional change in Baltimore City, Maryland, that mandates public disclosure of the gun offender registry. We exploit the sharp localized change in perceived crime risk after gun...
