We use a dynamic general equilibrium model featuring a banking sector to assess the interaction between macroprudential policy and monetary policy. We find that in “normal” times (when the economic cycle is driven by supply shocks) macroprudential policy generates only modest benefits for macroeconomic stability over a “monetary-policy-only” world. And lack of cooperation between the macroprudential authority and the central bank may even result in conflicting policies, hence suboptimal results. The benefits of introducing macroprudential policy tend to be sizeable when financial or housing market shocks, which affect the supply of loans, are important drivers of economic dynamics. In these cases a cooperative central bank will “lend a hand” to the macroprudential authority, working for broader objectives than just price stability in order to improve overall economic stability.
