Surges in firearm sales after mass shootings have been well documented in the United States. This study presents three main findings regarding the impact of mass shootings on firearm demand and the moderating roles played by political and regulatory climates. First, mass shootings led to an immediate but temporary increase in gun sales. This effect continued for approximately 3–6 months after the incidents and was larger for shootings with a greater number of fatalities. Second, the association between mass shootings and gun sales was significant only under Democratic presidents. The party affiliation of the state legislature and state-level gun control did not moderate this association. Third, the increased firearm sales after mass shootings did not result in a higher level of firearm ownership. It appeared most purchases were made by current gun owners stockpiling additional firearms, thus indicating the fear of stricter gun control as a likely motivation. This study offers the following policy implications: (a) the public debates concerning gun violence could have the unintended consequence of raising gun demand among current owners, (b) the message of tightening gun control could increase the total stock of firearms in circulation, and (c) the regulations to prevent future mass shootings may be better addressed by the state government as a state-level regulation does not trigger demand response among potential consumers.
