Medium-Term Money Neutrality and the Effective Lower Bound
Conventional wisdom suggests that medium-term money neutrality imposes strong limitations on the effects of monetary policy. The point of this paper is that models with medium- and long-term money neutrality are prone to generate non-existence of equilibria at the effective lower bound (ELB) on interest rates. Non-existence is suggestive of sharp output contractions --- so-called contractionary black holes --- at the ELB. Paradoxically, the case for expansionary monetary policy at the ELB is even stronger in models that feature near money neutrality. The results highlight the benefits of a monetary policy regime in which the central bank temporarily overshoots its inflation target once confronted by the ELB.
