The COVID-19 epidemic in emerging markets risks a combined health, economic, and debt crisis. We integrate a standard epidemiology model into a sovereign default model and study how default risk impacts the ability of these countries to respond to the epidemic. Lockdown policies are useful for...

A new aggregation scheme used to measure the sources of fiscal financing of indebted countries suggests that there was a fundamental improvement in the seniority of domestic debt at the expense of foreign bank debt during the late 1980s. We argue that this was the revenue maximizing response of...

Over 60% of US households with credit cards are currently borrowing -- i.e., paying interest -- on those cards. We attempt to reconcile the high rate of credit card borrowing with observed levels of life cycle wealth accumulation. We simulate a lifecycle model with five properties that create...

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...

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...

I develop two models in which debt repurchases by highly indebted sovereign nations are advantageous for all parties. The models are based on the idea that when sovereign debts are large, bargaining costs are large. Creditors spend more resources convincing the debtor that they are tough when...

Nominal debt provides consumption-smoothing benefits if it can be inflated away during recessions. However, we document empirically that countries with more countercyclical inflation, where nominal debt provides better consumption-smoothing, issue more foreign-currency debt. We propose that...

We present a simple model of sovereign debt crises in which a country chooses its optimal mix of short and long-term bonds subject to standard contracting frictions: the country cannot commit to repay its debts nor to a specific path of future debt issues, and contracts cannot be made state...

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...

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;...
