Looking Down the Barrel of a Loaded Gun: The Effect of Mandatory Handgun Purchase Delays on Homicide and Suicide

We exploit within-state variation across time in both the existence and length of statutory delays – both explicit wait periods and delays created by licensing requirements – between the purchase and delivery of a firearm to examine the effect of purchase delays on homicides and suicides. We find that the existence of a purchase delay reduces firearm-related suicides by between 2% and 5% with no statistically significant increase in non-firearm suicides. Purchase delays are not associated with statistically significant changes in homicide rates.
