Progress on the question of whether policymakers should respond directly to financial variables requires a realistic economic model that captures the links between asset prices, credit expansion, and real economic activity. Standard DSGE models with fully-rational expectations have difficulty...

We investigate the behavior of the equilibrium price-rent ratio for housing in a simple Lucas-type asset pricing model. We allow for time-varying risk aversion (via external habit formation) and time-varying persistence and volatility in the stochastic process for rent growth, consistent with...

We study the interaction between monetary policy and household debt dynamics. To this end, we develop a dynamic stochastic general equilibrium model where household debt is amortized gradually, and only new loans are constrained by the current value of collateral. Long-term debt implies that...

We study the implications of multi-period loans for monetary and macroprudential policy, considering several realistic modifications - variable vs. fixed loan rates, non-negativity constraint on newly granted loans, and possibility for the collateral constraint to become slack - to an otherwise...
