The Political Economy of Sustainable Federations

This paper studies a constitutional framework that enables sustainable federative agreements. In the model, districts decide on local policies and envision the possibility of entering a federation. Focusing on rules for legislative bargaining in the federation, I find that a non-egalitarian bargaining rule, which assigns policy making power to one of the district's representatives is welfare inferior to the decentralized status quo. In contrast, under an egalitarian bargaining procedure, federation yields a welfare superior outcome. The analysis indicates the desirability of making such egalitarian bargaining rules credible.
