This paper compares the equilibrium dynamics of an economy facing an aggregate collateral constraint on external debt to the dynamics of an economy facing a collateral constraint imposed at the level of each individual agent. The aggregate collateral constraint is intended to capture an...

This paper establishes the existence of multiple equilibria in infinite-horizon open- economy models in which the value of tradable and nontradable endowments serves as collateral. In this environment, the economy displays self-fulfilling financial crises in which pessimistic views about the...

This paper contributes to a literature that studies optimal capital control policy in open economy models with pecuniary externalities due to flow collateral constraints. It shows that the optimal policy calls for capital controls to be lowered during booms and to be increased during recessions....

The authors study the impact that the liquidity crunch in 2008-2009 had on the U.S. economy's growth trend. To this end, the authors propose a model featuring endogenous productivity a la Romer and a liquidity friction a la Kiyotaki-Moore. A key finding in the authors' study is that liquidity...

We study the impact that the liquidity crunch in 2008-2009 had on the U.S. economy's growth trend. To this end, we propose a model featuring endogenous growth á la Romer and a liquidity friction á la Kiyotaki-Moore. A key finding in our study is that liquidity declined around the demise of...

We propose a parsimonious semiparametric method for macroeconomic forecasting during episodes of sudden changes. Based on the notion of clustering and similarity, we partition the time series into blocks, search for the closest blocks to the most recent block of observations, and with the...

We study the causes behind the shift in the level of U.S. GDP following the Great Recession. To this end, we propose a model featuring endogenous productivity à la Romer and a financial friction à la Kiyotaki–Moore. Adverse financial disturbances during the recession and the lack of strong...

We propose a parsimonious semiparametric method for macroeconomic forecasting during episodes of sudden changes. Based on the notion of clustering and similarity, we divide the series into blocks, search for the closest blocks to the most recent block of observations, and with the matched blocks...
