We propose a model that solves the crucial disconnect between business cycle models that treat default risk as an exogenous interest rate on working capital, and sovereign default models that treat output fluctuations as an exogenous process with ad-hoc default costs. The model explains observed...

An equilibrium model of financial crises driven by Irving Fisher's financial amplification mechanism features a pecuniary externality, because private agents do not internalize how the price of assets used for collateral respond to collective borrowing decisions, particularly when binding...

Two observations suggest that financial globalization played an important role in the recent financial crisis. First, more than half of the rise in net borrowing of the U.S. nonfinancial sectors since the mid 1980s has been financed by foreign lending. Second, the collapse of the U.S. housing...

Partial financial indexation in Chile has produced a system in which most bank deposits are 30-day nonindexed deposits or 90-day indexed deposits. This paper uses data on the interest rates of these financial assets to test the joint hypothesis of rational expectations, efficient arbitrage, and...

Emerging markets business cycle models treat default risk as part of an exogenous interest rate on working capital, while sovereign default models treat income fluctuations as an exogenous endowment process with ad-hoc default costs. We propose instead a general equilibrium model of both...

The 1990s Sudden Stops in emerging markets were a harbinger for the 2008 global financial crisis. During Sudden Stops, countries lost access to credit, causing abrupt current account reversals, and suffered Great Recessions. This paper reviews a class of models that yields quantitative...

What are the stylized facts that characterize the dynamics of credit booms and the associated fluctuations in macro-economic aggregates? This paper answers this question by applying a method proposed in our earlier work for measuring and identifying credit booms to data for 61 emerging and...

The European debt crisis shares features of the historical episodes of outright default on domestic public debt identified by Reinhart and Rogoff (2008) as a forgotten research subject. This paper proposes a theory of domestic sovereign default in which a government chooses debt and default...

In the 1990s, Sudden Stops in emerging markets were a harbinger of the 2008 global financial crisis. During these Sudden Stops, countries lost access to credit, which caused abrupt current account reversals, and suffered severe recessions. This article reviews a class of models that yield...

We study the short- and long-run effects of financial integration in emerging economies using a two-sector model with a collateral constraint on external debt and trading costs incurred by foreign investors. The probability of a financial crisis displays overshooting: It rises sharply initially...
