Research has shown that the unilateral accumulation of international reserves by a country can improve its own macro-financial stability. However, we show that when many countries accumulate reserves, the induced general equilibrium effects weaken financial and macroeconomic stability,...

The current account reversals, large recessions, and price collapses that define Sudden Stops contradict the predictions of a large class of models in which the current account is a vehicle for consumption smoothing and investment financing. This paper shows that the quantitative predictions of...

The 1990s emerging-markets crises were characterized by sudden reversals in inflows of foreign capital followed by unusually large declines in current account deficits, private expenditures, production, and prices of nontradable goods relative to tradables. This paper shows that these Sudden...

In this paper we document the cyclical properties of U.S. firms' financial flows. Equity payouts are procyclical and debt payouts are countercyclical. We develop a model with explicit roles for debt and equity financing and explore how the observed dynamics of real and financial variables are...

The volatility of US business cycles has declined during the last two decades. During the same period the financial structure of firms has become more volatile. In this paper we develop a model in which financial factors play a key role in generating economic fluctuations. Innovations in...

The 2008-2009 crisis was characterized by an unprecedented degree of international synchronization as all major industrialized countries experienced large macroeconomic contractions around the date of Lehman bankruptcy. At the same time countries also experienced large and synchronized...

In his seminal 1960 article Robert Mundell proposed a model of balance-of-payments crises in which confidence in the continuation of a currency peg depended on the observed holdings of central bank foreign reserves. We examine the implications of a reformulation of this view from the perspective...

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...

This paper proposes a methodology for measuring credit booms and uses it to identify credit booms in emerging and industrial economies over the past four decades. In addition, we use event study methods to identify the key empirical regularities of credit booms in macroeconomic aggregates and...
