What determines the sustainability of sovereign debt? We develop a model where myopic governments seek popularity but can nevertheless commit credibly to service external debt. They do not default when debt is low because they would lose access to debt markets and be forced to reduce spending;...

I develop a model in which sovereign debtors repay debt in order to maintain a reputation for repayment. Repayment gives creditors reason to think that the debtor will suffer adverse consequences if it defaults, so they continue to lend. I compare a situation in which competitive lenders earn a...

We identify the major public debt overhang episodes in the advanced economies since the early 1800s, characterized by public debt to GDP levels exceeding 90% for at least five years. Consistent with Reinhart and Rogoff (2010) and other more recent research, we find that public debt overhang...

Deleveraging from high debt can provoke deep recession with significant international side effects. The exchange rate of the deleveraging country will depreciate in the short run and appreciate in the long run. The real interest rate will fall by more than in the rest of the world. Bounds and...

We address the question of whether and how a sovereign should reduce its external indebtedness when default is a significant possibility, with a particular focus on whether a sovereign should buy back or dilute existing long-term sovereign bonds. Our main finding is that when reduction of debt...

This paper shows that whether or not a sovereign can borrow to smooth consumption depends both on how consumption smoothing is achieved, whether by contingent debt issuance or by contingent debt servicing, and on the exact nature of the penalty for debt repudiation. If a sovereign that...

The G-8 Multilateral Debt Relief Initiative (MDRI) is the next step of the Highly Indebted Poor Countries Initiative (HIPC). There are two reasons why MDRI is unlikely to help poor countries. First, the amount of money at stake is trivial. The roughly $2 billion of annual debt payments to be...

The textbook optimal policy response to an increase in government debt is simple—monetary policy should actively target inflation, and fiscal policy should smooth taxes while ensuring debt sustainability. Such policy prescriptions presuppose an ability to commit. Without that ability, the...

In the context of a model that distinguishes between large money center banks and smaller regional banks, we show that the percentage of a country's debt held by the large banks affects the secondary market price of that country's debt: the higher the concentration of the debt, the higher the...

We study the interactions between sovereign debt default and maturity choice in a setting with limited commitment for repayment as well as future debt issuances. Our main finding is that under a wide range of conditions the sovereign should, as long as default is not preferable, remain passive...
