Abstract: | We introduce multiperiod mortgage loans, fixed interest rate, a lower bound constraint on newly granted loans, and a possibly slack collateral constraint, in an otherwise standard Dynamic Stochastic General Equilibrium (DSGE) model with housing. Our nonlinear estimation shows that all those features are important to understand the evolution of mortgage debt during the recent U.S. housing market boom and bust. The transmission of monetary policy becomes dependent on the housing cycle, with weaker effects when house prices are high or start falling sharply. Higher average loan duration makes monetary policy less effective, eventually leading to asymmetric responses to positive and negative monetary shocks. |
