Does the impact of monetary policy depend on the inflation level?
Core argument: When U.S. inflation is below 5.5% — the case for most of the post-WWII sample — the authors' model identifies no meaningful effects of monetary policy on labor markets, a result they say is consistent with the U.S. economy's recent "soft landing.".
We find that the effects of monetary policy vary substantially with the underlying level of inflation in the economy. For most of our post-WWII sample, inflation has been less than 5.5% in the U.S., which our model identifies as a period during which monetary policy has no meaningful effects on labor markets. Even though our sample ends in 2007 due to the availability of the instrument series used to identify the effects of monetary policy, our results are consistent with the recent “soft landing” of the U.S. economy. On the other hand, when inflation is between 5.5 and 11%, the effects of monetary policy are larger and longer-lasting, since variables are much more persistent in this regime, and the effects of monetary policy on unemployment are sizable and significant.
