The maturity of government debt varies across countries and time. We document that in times of high inflation the maturity of debt is shorter and the level of debt is lower. We develop a model of the maturity of debt based on government credibility. We show that credible government who can...

During the recent U.S. financial crisis, the large decline in economic activity and credit was accompanied by a large increase in the dispersion of growth rates across firms. However, even though aggregate labor and output fell sharply during this period, labor productivity did not. These...

We develop a multicountry model in which default in one country triggers default in other countries. Countries are linked to one another by borrowing from and renegotiating with common lenders with concave payoffs. A foreign default increases incentives to default at home because it makes new...

Researchers have documented that in the recent financial crisis the large decline in economic activity and credit has been accompanied by a large increase in the dispersion of growth rates across firms. We build a quantitative general equilibrium model in which financial frictions interact with...

This paper studies the aggregate implications of imperfect risk-sharing implied by a class of New Keynesian models with idiosyncratic income risk and incomplete financial markets. The models in this class can be equivalently represented as an economy with a representative household that has...

A large literature has developed quantitative versions of the Eaton and Gersovitz (1981) model to analyze default episodes on external debt. In this paper, we study whether the same framework can be applied to the analysis of debt crises in which domestic public debt plays a prominent role. We...

Financial crises typically arise because firms and financial institutions choose balance sheets that expose them to aggregate risk. We propose a theory to explain these risk exposures. We study a financial accelerator model where entrepreneurs can issue state-contingent claims to consumers. Even...

Foreign currency borrowing is perceived as a source of financial instability in emerging markets. We propose a theory where liability dollarization arises from an insurance motive of domestic savers. Because financial crises are associated with currency depreciations, savers are reluctant to...

We study the problem of a monetary authority pursuing an exchange rate policy that is inconsistent with interest rate parity because of a binding zero lower bound constraint. The resulting violation in interest rate parity generates an inflow of capital that the monetary authority needs to...

This paper uses the information contained in the joint dynamics of government's debt maturity choices and interest rate spreads to quantify the importance of self-fulfilling expectations in sovereign bond markets. We consider a model of sovereign borrowing featuring endogenous debt maturity,...
