Abstract

This paper examines the welfare implications of international monetary co-operation using a stylised two-country New Keynesian general equilibrium model of imperfect information. We show that setting a self-oriented monetary policy rule generally leads to welfare gains relative to passive monetary policy even when central banks do not have perfect information about the foreign economy. However, information sharing between central banks in this set-up, by itself, has ambiguous welfare implications. Gains from monetary co-ordination are largest when productivity shocks are negatively correlated across countries.
