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...

This paper studies how distributional and electoral concerns shape sovereign default incentives within a quantitative model of sovereign debt with heterogeneous agents and non-linear income taxation. The small open economy is characterized by a two-party system in which the left-wing party has a...

This paper tests the effect of sovereign debt structure on default likelihood. Sovereign debt structure is identified on the basis of maturity, creditor type and currency composition. The paper uses panel logit model to estimate the likelihood of default. The results provide evidence that...

This paper explores the drivers of sovereign defaults in 100 countries over the period 1996-2012. We build a new data set of sovereign defaults and find that default events on local and foreign currency bonds are equally likely. However, governments default under different economic and financial...

• The IMF staff's 2013 proposal to reprofile (i.e., stretch out for a short period without haircutting principal or interest) the maturing debt of a country that has lost market access is a sensible policy in cases where the IMF is uncertain whether the country's debt stock is sustainable.•...

We present an analytically tractable two-country New Open Economy Macroeconomics model of a currency union featuring an overlapping gen- erations structure of the Blanchard (1985)-Yaari (1965) type. It enables us to study the transmission and spillover effects of a wider range of fiscal shocks...

We present a two-country New Open Economy Macroeconomics model of a currency union featuring an overlapping generations structure of the Blanchard (1985)-Yaari (1965) type as well as monopolistic frictions and staggered adjustment in the goods and labor market. We allow for public investment and...

Public debt is one of the important economic variables that quantitatively describes a nation's economy. Because bankruptcy is a risk faced even by institutions as large as governments (e.g. Iceland), national debt should be strictly controlled with respect to national wealth. Also, the problem...

This Feature considers the debts of quasi-sovereign states in light of proposals to let them file for bankruptcy protection. States that have ceded some but not all sovereign prerogatives to a central government face distinct challenges as debtors. It is unhelpful to analyze these challenges...

This paper seeks to eliminate or reduce confusions about (related) key concepts such as the risk free rate, safe assets and sovereign risk in policy and academic discussions. A lack of consensus and confusions on how to define, measure and price “sovereign risk” is an important obstacle in...
