Bank specialization, mortgage lending and house prices

Abstract

This paper studies the link between banks’ geographic specialization and the growth in their mortgage lending. Specialized banks increase their lending relatively less during the boom (2004 - 2006) and they experience a lower reduction in their loans through the following bust (2007 - 2009). In the aggregate, bank specialization has an impact on the overall credit rather than a mere reallocation of lending: MSAs with a higher exposure to specialized banks experience less expansion and contraction in mortgages. As a result, higher bank specialization is associated with a less severe boom and bust cycle in house prices.
