How does Financial Vulnerability amplify Housing and Credit Shocks

In this paper we study how households’ financial vulnerability affects the propagation of housing and credit shocks. First, we estimate a non-linear model generating impulse responses that depend on the evolution of households' Debt to Service Ratio, i.e. the fraction of income that households use to pay back their debt. Second, we use sign restrictions to jointly identify a wide set of financial and economic shocks. We find that financial vulnerability: i) amplifies the response of the economy to housing shock, ii) makes the response to expansionary credit shocks less persistent and even negative after the first year since the arrival of the shock. Finally, overall recessionary shocks have larger effects with respect to expansionary ones of the same size.
