This paper examines the US gun-related murder (GM) rate and places it in an international context. The US GM rate is 27 times the average rate for 22 other developed countries (ODC). Its gun ownership rate is 5.4 times that of ODC and the murder rate per gun is 5 times that of ODC. Thus, as is...

The controversies surrounding Stand Your Ground laws have recently captured the nation's attention. Since 2005, eighteen states have passed laws extending the right to self-defense with no duty to retreat to any place a person has a legal right to be, and several additional states are debating...

To what extent, and under what conditions, does access to arms fuel violent crime? To answer this question, we exploit a unique natural experiment: the 2004 expiration of the U.S. Federal Assault Weapons Ban exerted a spillover on gun supply in Mexican municipios near Texas, Arizona and New...

This paper uses a "local average treatment effect" (LATE) framework in an attempt to disentangle the separate effects of criminal and noncriminal gun prevalence on violence rates. We first show that a number of previous studies have failed to properly address the problems of endogeneity, proxy...
