A Note on Post-Modern Monetary Policy

This paper surveys the roots of the modern literature on monetary policy, and illustrates the convergence that occurs between open-economy approaches and the micro foundations of monetary policy. From the Banking School versus Currency School debate to the “credibility versus flexibility” refinement, monetary policy has a long history of scholarly works. Although it may be hard to imagine that there is still room for innovations, the current developments of the literature on open-economy monetary policy seem to spawn a new and essential branch.
