Sovereign debt and structural reforms

Abstract

We construct a dynamic theory of sovereign debt and structural reforms with three interacting frictions: limited enforcement, limited commitment, and incomplete markets. A sovereign country in recession issues debt to smooth consumption and makes reforms to speed up recovery. The sovereign can renege on debt by suffering a stochastic cost, in which case debt is renegotiated. The competitive Markov equilibrium features large fluctuations in consumption and reform effort. We contrast the equilibrium with an optimal contract with one-sided commitment. A calibrated model can match several salient facts about debt crises. We quantify the welfare effect of relaxing different frictions.
