How is monetary policy transmitted through its impact on mortgage borrowings? How does this transmission mechanism depend on whether mortgages are fixed or floating rate? To address these questions, we add a model of financial institutions’ behaviour to a dynamic general equilibrium model in which some households face credit constraints. We use this model to analyse the real effects of inflatio...

The valuation model is comprised of an exogenous OTS prepayment model, a stochastic interest rate process, and other servicing fees and costs, all of which jointly determine the servicing contract’s ...
