Constrained efficiency without commitment

Abstract

We consider an infinite horizon economy where agents share income risks by trading a complete set of contingent claims but cannot commit to their promises. Allocations are restricted to be self-enforcing relative to autarchic reservation utilities. We provide a general characterization of constrained Pareto efficiency without assuming that there are uniform gains to trade. Our results extend those in Bloise and Reichlin (2011) in several aspects.
