"We show how to decentralize constrained efficient allocations that arise from enforcement constraints between sovereign nations.In a pure exchange economy, these allocations can be decentralized with private agents acting competitively and taking as given government default decisions on foreign...

This paper is structured in three parts. The first part outlines the methodological steps, involving both theoretical and empirical work, for assessing whether an observed allocation of resources across countries is efficient. The second part applies the methodology to the long-run allocation of...

This study demonstrates how constrained efficient allocations can arise endogenously as equilibria in an economy with a limited ability to enforce contracts and with private agents behaving competitively, taking a set of taxes as given. The taxes in this economy limit risk-sharing and arise in...
