Abstract

In this paper, we analyze the causal effect of mandatory firearm waiting periods on suicide rates using difference-in-differences methodology. We find waiting periods reduce overall firearm suicides by 12% (0.92 deaths per 100,000), with steeper declines among white individuals (37%) and adults over 55 (40%). We find no evidence of substitution toward non-firearm methods; conversely, repealing these laws increases firearm suicides. Back-of-the-envelope calculations suggest that waiting periods prevent approximately 3,000 deaths annually, generating $41 billion in social benefits. These findings demonstrate that "cooling-off periods" effectively disrupt the transition from suicidal ideation to action by delaying access to lethal means.
