Does gun ownership lead to increased crime? This question is hotly debated, especially in the United States. Proponents of gun control point to gun-related violence, while proponents of the right to bear arms argue that gun ownership has a deterrent effect. David Schindler and Christoph Koenig found that purchase delays also had 3% lower homicide rates.
Empirically, going beyond mere correlations and establishing the causal effect of gun ownership on crime is a difficult endeavor. In Discussion Paper David Schindler (Tilburg Law and Economics Center) and his co-author Christoph Koenig (University of Bristol) use the demand shock after the 2012 shooting at Sandy Hook Elementary School to study the effect of purchase delay laws on homicides. The fear of tighter gun control legislation led to record sales of firearms across the US in the six months following the shooting.
The authors show, however, that states with purchase delay laws, which typically impose a mandatory waiting period before buyers can obtain their firearm, witnessed a smaller increase in handgun sales than states without such laws.
