This paper studies regime dependence in the effects of monetary policy shocks for the U.S. using a threshold vector autoregressive model. In a high inflation regime the standard results from the literature obtain. In a low inflation regime output shows no significant response to monetary policy...

This paper studies regime dependence in macroeconomic dynamics in the U.S. using a threshold vector autoregressive model in which endogenous regime switches are triggered by the inflation rate. The model separates a high from a low inflation regime with both regimes being strongly persistent....

We assess the macroeconomic effects of the Eurosystem's asset purchases on the four largest euro area economies using simulation exercises that combine unconventional monetary policy shocks with a fixed policy rate for the duration of the purchase programme. We identify unconventional monetary...
