Abstract

We estimate the causal effect of a mortgage supply expansion on house prices by using an exogenous change in prudential regulation: the abolition in 2006 of a banks' maturity transformation limit. After the repeal of the prudential rule, credit increased only for the banks that were previously constrained by the regulation, while it remained unchanged for the other banks. Such differential response rules out demand-based explanations and fully identify the rule abolition as an exogenous shock that we exploit as an instrument for mortgage supply expansion. We estimate the elasticity of house price growth to new mortgage credit to be close to 5 percent. Our results also show that the effect of a mortgage supply expansion on house prices significantly differs across municipalities' and borrowers' characteristics.
