The 2015 Addis Ababa Action Agenda recognized the need for policies aimed at maintaining longterm debt sustainability. This paper describes a set of commonly used definitions of debt sustainability and shows that none of them focuses on long-term debt sustainability. It then discusses concept...

This paper surveys recent economic and legal literature on sovereign debt in light of the COVID-19 shock. Most of the core theoretical contributions we review across the two disciplines hinge on immunity, and the sovereign borrower's consequent inability to commit to repay foreign creditors, as...

We review the state of the sovereign debt literature and point out that the canonical model of sovereign debt cannot be easily reconciled with several facts about sovereign debt pricing and servicing.
