Are the Effects of Monetary Policy Asymmetric?

Abstract

By building on the Hamilton (1989) Markov switching model, we examine questions like: Does monetary policy have the same effect in expansions and recessions? Given that the economy is currently in a recession, does a fall in interest rates increase the probability of an expansion? Does monetary policy have an incremental effect on the growth rate within a given state, or does it only affect the economy if it is sufficiently strong to induce a state change (e.g., from recession to expansion)? As suggested by models with sticky prices or finance constraints, interest rate changes have larger effects during recessions.
