In this paper, the author considers the sovereign debt in the form of one-period government bonds with default risk, which can be purchased by and traded among domestic and foreign investors. She shows that the weight assigned to the lenders' interest by the borrowing government at the time of...

This paper presents a theory of sovereign borrowing and lending when there is no court to enforce repayment obligations. Specifically, I extend the costly state verification approach in financial contracting to include an ex-post repayment decision in which the borrower repays creditors to avoid...

This paper analyzes the impact of debt forgiveness on economic equilibrium. Since the root cause of an economic crisis is debt, eradicating the root may solve the problem. However, it does not prevent future crises from occurring. It is found that debt relief in a global scale can help reach...

How do oil price movements affect sovereign spreads in an oil-dependent economy? I develop a stochastic general equilibrium model of an economy exposed to co-moving oil price and output processes, with endogenous sovereign default risk. The model explains a large proportion of business cycle...

• 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 express the opinion that sovereign debt sustainability analysis must be augmented by stochastic correlated risk factors and a risk measure to capture tail effects. Crisis situations can thus be adequately specified and analyzed with sufficient accuracy to warrant the relevance of policy...

Can debt moratoria help countries weather negative shocks? We study the bond market effects of an official debt service suspension endorsed by the international community during the Covid-19 pandemic. Using daily data on sovereign bond spreads and synthetic control methods, we show that...

This paper develops a non-stochastic sovereign-debt dynamic model, with increasing cost of capital. It finds that there are parameters for which there is a stable fixed borrowing level, and there are parameters for which the model depicts the case of serial defaulters. Levels of debt that tend...

This chapter is on quantitative models of sovereign debt crises in emerging economies. We interpret debt crises broadly to cover all of the major problems a country can experience while trying to issue new debt, including default, sharp increases in the spread and failed auctions. We examine the...

This paper shows that the optimal sovereign lending contract is state-contingent when a government can default. It provides a theoretical basis for the specification of optimal state-contingent debt instruments (SCDIs) in countries subject to large shocks that can be observed and verified by all...
