The Impact of Balance Sheet Lending versus Securitization Booms on the Severity of the Great Recession

Abstract

I separately estimate the effect of local credit booms driven by balance sheet lending and those driven by securitization during the 2002-2006 period on the severity of the 2007-2009 recession in the United States. I construct a novel dataset, linking publicly available data on residential mortgage originations from the Home Mortgage Disclosure Act together with bank financial statements and county level economic outcomes. I exploit geographic variation in bank origination activity across counties to construct county level measures of exposure to securitization and balance sheet lending activity during the 2002-2006 period that are orthogonal to local economic conditions. Results show that 2002-2006 securitization exposure is predictive of sharper declines in home prices, employment, and a rise in mortgage delinquencies during the subsequent crisis period. The same is not true for balance sheet lending, which does not affect crisis period home prices and generates a drop in employment that is con fined to the nontradable sector. Results suggest that this difference is driven by risk taking that is specific to securitized lending. Balance sheet booms generate an expansion in lending to higher quality borrowers, while securitization booms increase credit availability at the lower end of the credit distribution.
