We study gains from introducing a common numerical fiscal rule in a "Union" of model economies facing sovereign default risk. We show that among economies in the Union, there is significant disagreement about the common debt limit the Union should implement: the limit preferred by some economies...

This paper studies the role of IMF-supported programs in mitigating the likelihood of subsequent sovereign defaults in borrowing countries. Using a panel of 106 developing countries from 1970 to 2016 and an entropy balancing methodology, we find that IMF-supported programs significantly reduce...

With public debt soaring across the world, a growing concern is whether current debt levels are a harbinger of fiscal crises, thereby restricting the policy space in a downturn. The empirical evidence to date is however inconclusive, and the true cost of debt may be overstated if interest rates...

Using a quantitative sovereign default model, we characterize constrained efficient borrowing by a Ramsey government that commits to income-history-contingent borrowing paths taking as given ex-post optimal future default decisions. The Ramsey government improves upon the Markov government...

This article surveys the literature on sovereign debt sustainability from its origins in the mid-1980s to the present, focusing on four debates. First, the shift from an "accounting based" view of debt sustainability, evaluated using government borrowing rates, to a "model based" view which uses...

Public and private sector balance sheets are an important component to any analysis of debt sustainability. A vulnerable and indebted private sector can become a sudden liability for the government; alternatively, resilient household and bank balance sheets may reveal potential sources of...

This paper examines the causes, processes, and outcomes of Barbados' 2018-19 sovereign debt restructuring-its first ever. The restructuring was comprehensive, featuring several rarely used approaches, including the restructuring of treasury bills, and the use of a retrofitted collective action...
