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...

We analyze the ups and downs in economic growth in recent decades by constructing a model with recurrent bubbles, crashes, and endogenous growth. Once realized, bubbles crowd in investment and stimulate economic growth, but expectation about future bubbles crowds out investment and reduces...

We study the interaction between borrowers' and banks' solvency in a quantitative macroeconomic model with financial frictions in which bank assets are a portfolio of defaultable loans. We show that ex-ante imperfect diversification of bank lending generates bank asset returns with limited...
