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...

The last decade or so has seen a mushrooming of new sovereign debt databases covering long time spans for several countries. This represents an important breakthrough for economists who have long sought to, but been unable to tackle, first-order questions such as why countries have differential...

As a response to economic crises triggered by COVID-19, sovereign debt standstill proposals emphasize debt payment suspensions without haircuts on the face value of debt obligations. We quantify the effects of standstills using a standard default model. We find that a one-year standstill...

Although the Netherlands entered the so-called Great Lockdown with a strong fiscal position, the Dutch fiscal balance is projected to deteriorate by an unprecedented magnitude, largely as a result of necessary fiscal measures deployed to weather the economic impact of the COVID-19 pandemic.

Do Highly Indebted Poor Countries (HIPCs) suffer from a debt overhang? Is debt relief going to improve their growth rates? To answer these important questions, we look at how the debt-growth relationship varies with indebtedness levels and other country characteristics in a panel of developing...

Sovereign debt restructurings are perceived as inflicting large losses to bondholders. However, many bonds feature high coupons and often exhibit strong post-crisis recoveries. To account for these aspects, we analyze the long-term returns of sovereign bonds during 32 crises since 1998, taking...

This paper develops new error assessment methods to evaluate the performance of debt sustainability analyses (DSAs) for low-income countries (LICs) from 2005-2015. We find some evidence of a bias towards optimism for public and external debt projections, which was most appreciable for LICs with...
