Abstract

We characterize the joint optimal implementation of macroprudential and monetary policies in a New Keynesian model where endogenous supply-side financial frictions generate inflationary credit spreads. State-contingent macroprudential interventions help to stabilize volatile spreads, and substantially alter the transmission of optimal monetary policy under both discretion and commitment. In 'normal times', macroprudential policies replicate the first-best allocation. In liquidity traps, financial interventions remove the zero lower bound restriction on the nominal policy rate, thus minimizing output costs following both deflationary (inflationary) demand (financial) shocks. Discretionary and commitment policies with macroprudential taxes deliver equivalent welfare gains.
