Equilibria in Firearm Ownership: Modeling a Partially Coordinated Market

For many individuals, the decision to own a firearm resembles a strategic coordination game. Each individual’s decision is not only determined by their individual beliefs but also by the ownership rate within their community. This theoretical model of a coordinated goods market shows how some markets observe stable equilibria for multiple firearm ownership rates. At the threshold between markets settling on a single equilibrium or facing two distinct equilibria a small policy shift can result in a disproportionately large shift in firearm ownership
