Credit Supply and the Housing Boom

Abstract:

The housing boom that preceded the Great Recession was due to a progressive loosening of lending constraints in the residential mortgage market. This view is consistent with a number of empirical observations, such as the rapid increase in house prices and household debt, the stability of debt relative to collateral values, and the fall in mortgage rates. These empirical facts are difficult to reconcile with the popular view that attributes the housing boom to a loosening of borrowing constraints associated with lower collateral requirements.
