Abstract

This paper investigates several contested issues over how concealed handguns affect crime. Whether accounting for robust errors with clustering or reducing measurement error in the crime rates, the results consistently show large drops in violent crime rates after right-to-carry laws are adopted. By six years after the law, murder rates have fallen by 9 percent, rape by 11 percent, and robbery by 7 percent.
