We show that a model with imperfectly forecastable changes in future productivity and an occasionally binding collateral constraint can match a set of stylized facts about "sudden stop" events. "Good" news about future productivity raises leverage during times of expansion, increasing the...

The housing boom that preceded the Great Recession was the result of an increase in credit supply driven by looser lending constraints in the mortgage market. This view on the fundamental drivers of the boom is consistent with four empirical observations: the unprecedented rise in home prices,...

We examine the dynamic effects of credit shocks using a large data set of U.S. economic and financial indicators in a structural factor model. The identified credit shocks, interpreted as unexpected deteriorations of credit market conditions, immediately increase credit spreads, decrease rates...

We document the emergence of a disconnect between mortgage and Treasury interest rates in the summer of 2003. Following the end of the Federal Reserve's expansionary cycle in June 2003, mortgage rates failed to rise according to their historical relationship with Treasury yields, leading to...

Credit spreads display occasional spikes and are more strongly countercyclical in times of financial stress. Financial crises are extreme cases of this nonlinear behavior, featuring deep recessions and sharp losses in bank equity. We develop a macroeconomic model with a banking sector in which...

In a financial system in which balance sheets are continuously marked to market, asset price changes appear immediately as changes in net worth, eliciting responses from financial intermediaries who adjust the size of their balance sheets. We document evidence that marked-to-market leverage is...

We use a two-country New Keynesian model with balance sheet constraints to investigate the magnitude of international spillovers of U.S. monetary policy. Home borrowers obtain funds from domestic households in domestic currency, as well as from residents of the foreign economy (the United...

This paper explores the role of capital flows and exchange rate dynamics in shaping the global economy's adjustment in a liquidity trap. Using a multi-country model with nominal rigidities, we shed light on the global adjustment since the Great Recession, a period when many advanced economies...

Domestic prudential regulation can have unintended effects across borders and may be less effective in an environment where banks operate globally. Using U.S. micro-banking data for the first quarter of 2000 through the third quarter of 2013, this study shows that some regulatory changes indeed...

There is a new and now large literature analyzing government policies for financial stability based on models with endogenous borrowing constraints. These normative analyses build upon the concept of constrained efficient allocation, where the social planner is constrained by the same borrowing...
