Sovereign Defaults and Debt Sustainability: The Debt Recovery Channel

This paper focuses on the debt recovery channel linking the dynamics of public debt to partial sovereign defaults. We build a simple model which incorporates sovereign default and a debt recovery rule. It depends on a parameter that allows for partial debt recovery. We show that the maximum debt-to-GDP ratio that a country can sustain without defaulting is increasing, nonlinear, and sensitive to the debt-recovery parameter. A higher debt recovery parameter increases the fiscal space but worsens the financial position of a borrowing country after a default episode. We show the empirical relevance of this channel for estimating country-specific fiscal spaces.
