Abstract

This paper studies the interaction of international shadow banking with monetary and macroprudential policy in a two-country currency union DSGE model. We fiÂ…nd evidence that cross-country fiÂ…nancial integration through the shadow banking system is a source of fiÂ…nancial contagion in response to idiosyncratic real and fiÂ…nancial shocks due to harmonization of fiÂ…nancial spheres. The resulting high degree of business cycle synchronization across countries, especially for Â…financial variables, makes union-wide policy tools more ffective. Nevertheless, optimal monetary policy at the union-level is too blunt an instrument to adequately stabilize business cycle downturns and needs to be accompanied by macroprudential regulation. Our welfare analysis reveals that the gains from the availability of country-speciÂ…c prudential tools vanish with the degree of fiÂ…nancial integration as union-wide macroprudential regulation is able to effectively reduce losses among the union members.
