An equilibrium voting model of federal standards with externalities

This paper proposes a framework for studying policy making in a federal system in the presence of spillover externalities. Local jurisdictions choose local policies by majority rule subject to standards that are set by majority rule at the federal level. We characterize the induced preferences of voters for federal policies, prove existence of local majority rule equilibrium, provide an example of non-existence of global majority rule equilibrium, and explore the welfare properties of federal standards in the presence of spillovers.
