Abstract Illiquidity in short-term credit markets during the financial crisis might have severely curtailed the supply of nonbank consumer credit. Using a new data set linking every car sold in the United States to the credit supplier involved in each transaction, we find that the collapse of the asset-backed commercial paper market reduced the financing capacity of such nonbank lenders as captive leasing companies in the automobile industry. As a result, car sales in counties that traditionally depended on nonbank lenders declined sharply. Although other lenders increased their supply of credit, the net aggregate effect of illiquidity on car sales is large and negative. We conclude that the decline in auto sales during the financial crisis was caused in part by a credit supply shock driven by the illiquidity of the most important providers of consumer finance in the auto loan market. These results also imply that interventions aimed at arresting illiquidity in short-term credit markets might have helped contain the real effects of the crisis.

Exploiting variation in the timing of resets of adjustable-rate mortgages (ARMs), we find that a sizable decline in mortgage payments (up to 50 percent) induces a significant increase in car purchases (up to 35 percent). This effect is attenuated by voluntary deleveraging. Borrowers with lower incomes and housing wealth have significantly higher marginal propensity to consume. Areas with a larger share of ARMs were more responsive to lower interest rates and saw a relative decline in defaults and an increase in house prices, car purchases, and employment. Household balance sheets and mortgage contract rigidity are important for monetary policy pass-through. (JEL D12, D14, E43, E52, G21, R31)
