Liquidity risk and the credit Crunch of 2007-2008: evidence from micro-level data on mortgage loan applications

Recent empirical studies have shown that during the financial crisis of 2007-2008 banks that were more heavily exposed to liquidity risk contracted their supply of credit more sharply. I contribute to the identification of this effect by relying on the use of micro-level data on US mortgage loan applications, which allows me to identify liquidity risk as an important determinant of the contraction of credit in the mortgage market, but as separate from the precipitous fall in credit demand, disruptions in the securitization and subprime markets, shifts in asset risk, and changing risk-aversion among loan officers.
