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 ¨¢ la Romer and a liquidity friction ¨¢ la Kiyotaki-Moore. A key finding in our study is that liquidity declined around the demise of...

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...
