Optimal Bailouts in Banking and Sovereign Crises
We study optimal bailout policies amidst banking and sovereign crises. Our model features sovereign borrowing with limited commitment, where domestic banks hold government debt and extend credit to the private sector. Bank capital shocks can trigger banking crises, prompting the government to consider extending guarantees over bank assets. This poses a trade-off: Larger bailouts relax financial frictions and increase output, but increase fiscal needs and default risk (creating a ‘diabolic loop’). Optimal bailouts exhibit clear properties. The fraction of banking losses the bailouts cover ...

A model of the Twin Ds: optimal default and devaluation
This paper characterizes jointly optimal default and exchange-rate policy in a small open economy with limited enforcement of debt contracts and downward nominal wage rigidity. Under optimal policy, default occurs during contractions and is accompanied by large devaluations. The latter inflate away real wages, thereby avoiding massive unemployment. Thus, the Twin Ds phenomenon emerges endogenously as the optimal outcome. In contrast, under fixed exchange rates, optimal default takes place in the context of large involuntary unemployment. Fixed-exchange-rate economies are shown to have ...

Sovereign Default in the US
In the absence of a judicial mechanism to reduce the debt burden of a sovereign member of our Union, the resolution process can be quick but perhaps too indifferent to the health, safety, and welfare of the affected residents. In this paper, I use evidence from the Arkansas state archives to provide a description of the events surrounding the default of the state in 1933. I examine the evolution of the negotiations, the outcomes, and the role of fiscal policy.

Optimal Domestic (and External) Sovereign Default
Infrequent but turbulent episodes of outright sovereign default on domestic creditors are considered a ?forgotten history? in macroeconomics. We propose a heterogeneous- agents model in which optimal debt and default on domestic and foreign creditors are driven by distributional incentives and endogenous default costs due to value of debt for self-insurance, liquidity, and risk-sharing. The government?s aim to redistribute resources across agents and through time in response to uninsurable shocks produces a rich dynamic feedback mechanism linking debt issuance, the distribution of government ...

Optimal Bailouts in Banking and Sovereign Crises
We study optimal bailout policies in the presence of banking and sovereign crises. First, we use European data to document that asset guarantees are the most prevalent way in which sovereigns intervene during banking crises. Then, we build a model of sovereign borrowing with limited commitment, where domestic banks hold government debt and also provide credit to the private sector. Shocks to bank capital can trigger banking crises, with government sometimes finding it optimal to extend guarantees over bank assets. This leads to a trade-off: Larger bailouts relax domestic financial frictions ...

History Remembered: Optimal Sovereign Default on Domestic and External Debt
Infrequent but turbulent overt sovereign defaults on domestic creditors are a ?for- gotten history? in macroeconomics. We propose a heterogeneous-agents model in which the government chooses optimal debt and default on domestic and foreign creditors by balancing distributional incentives versus the social value of debt for self-insurance, liquidity, and risk-sharing. A rich feedback mechanism links debt issuance, the distribution of debt holdings, the default decision, and risk premia. Calibrated to Eurozone data, the model is consistent with key long-run and debt-crisis statistics. Defaults ...
Working Paper
Inflation, Debt, and Default
We study how the co-movement of inflation and economic activity affects real interest rates and the likelihood of debt crises. First, we show that for advanced economies, periods with procyclical inflation are associated with lower real interest rates. Procyclical inflation implies that nominal bonds pay out more in bad times, making them a good hedge against aggregate risk. However, such procyclicality also increases sovereign default risk when the economy deteriorates, since the government needs to make larger (real) payments. In order to evaluate both effects, we develop a model of ...

How Do Real Exchange Rates Vary in Hard and Soft Sovereign Defaults?
Sovereign defaults differ tremendously in creditor losses. Existing research has established that hard defaults (large creditor loss defaults) are associated with worse outcomes for GDP per capita than soft defaults. In this article, we document that hard defaults also feature worse real exchange rate depreciations.

Optimal Time-Consistent Taxation with Default
We study optimal time-consistent distortionary taxation when the repayment of government debt is not enforceable. The government taxes labor income or issues noncontingent debt in order to finance an exogenous stream of stochastic government expenditures. The government can repudiate its debt subject to some default costs, thereby introducing some state-contingency to debt. We are motivated by the fact that domestic sovereign default is an empirically relevant phenomenon, as Reinhart and Rogoff (2011) demonstrated. Optimal policy is characterized by two opposing incentives: an incentive to ...
Working Paper
Domestic Debt and Sovereign Defaults
This paper examines how domestic holdings of government debt affect sovereign default risk and government debt management. I develop a dynamic stochastic general equilibrium model with both external and domestic debt that endogenously generates output contraction upon default. Domestic holdings of government debt weaken investors' balance sheets and induce a contraction of credit and output upon default. I calibrate the model to the Argentinean economy and show that the model reproduces key empirical moments. Introducing domestic debt also yields relevant normative implications. While ...
