In the past three decades, governments in emerging markets have accumulated large amounts of international reserves, especially those with fixed exchange rates. We propose a theory of reserve accumulation that can account for these facts. Using a model of endogenous sovereign default with...

This paper focuses on the 1995 Latin American and 1997 East Asian crises using an insurance-based model of financial crises. First the model of Dooley (forthcoming) is described. Second, some empirical evidence for an insurance model is presented. The key variables in this approach include the...

We study the optimal accumulation of international reserves in a quantitative model of sovereign default with long-term debt and a risk-free asset. Keeping higher levels of reserves provides a hedge against rollover risk, but this is costly because using reserves to pay down debt allows the...

We find that emerging markets appeared to be somewhat insulated from developments in U.S. financial markets from early 2007 to summer 2008. From that point on, however, emerging markets responded very strongly to the deteriorating situation in the U.S. financial system and real economy. Policy...

In this essay, we argue that key assumptions in international macroeconomic theory, though useful for understanding the economic relationships among developed countries, have been pushed beyond their competence to include relationships between developed economies and emerging markets. The...

We develop a quantitative equilibrium model of financial crises to assess the interaction between ex-post interventions in credit markets and the buildup of risk ex ante. During a systemic crisis, bailouts relax balance sheet constraints and mitigate the severity of the recession. Ex ante, the...

In this paper, we study the optimal design of financial safety nets under limited private credit. We ask when it is optimal to restrict ex ante the set of investors that can receive public liquidity support ex post. When the government can commit, the optimal safety net covers all investors....

This paper examines the role of the third party (the IMF) in resolving sovereign default on external debt. We first show that the effects of third party intervention in debt negotiations are quite sensitive to the assumed enforcement mechanism for sovereign debt. The model is then adapted to an...

Recent financial crises in emerging markets have been followed by temporary but substantial losses in output. This paper explores the possibility that threats of such losses are the dominant incentive for repayment of international debt. In this environment private debtors and creditors have...

This paper proposes a theory of foreign reserves as macroprudential policy. We study an open economy model of financial crises, in which pecuniary externalities lead to overborrowing, and show that by accumulating international reserves, the government can achieve the constrained-efficient...
