Household Leverage and the Recession of 2007 to 2009

We show that household leverage as of 2006 is a powerful statistical predictor of the severity of the 2007 to 2009 recession across U.S. counties. Counties in the U.S. that experienced a large increase in household leverage from 2002 to 2006 showed a sharp relative decline in durable consumption starting in the third quarter of 2006 - a full year before the official beginning of the recession in the fourth quarter of 2007. Similarly, counties with the highest reliance on credit card borrowing reduced durable consumption by significantly more following the financial crisis of the fall of 2008. Overall, our statistical model shows that household leverage growth and dependence on credit card borrowing as of 2006 explain a large fraction of the overall consumer default, house price, unemployment, residential investment, and durable consumption patterns during the recession. Our findings suggest that a focus on household finance may help elucidate the sources macroeconomic fluctuations
