To what extent is the recent spike in inflation driven by a change in its permanent component? We estimate a semi-structural model of output, inflation, and the nominal interest rate in the United States over the period 1900-2021. The model predicts that between 2019 and 2021 the permanent...

Observed inflation targets around the industrial world are concentrated at two percent per year. This chapter investigates the extent to which the observed magnitudes of inflation targets are consistent with the optimal rate of inflation predicted by leading theories of monetary nonneutrality....

The existing literature on the stabilizing properties of interest-rate feedback rules has stressed the perils of linking interest rates to forecasts of future inflation. Such rules have been found to give rise to aggregate fluctuations due to self-fulfilling expectations. In response to this...

This paper investigates whether permanent monetary tightenings increase inflation in the short run. It estimates, using U.S. data, an empirical and a New-Keynesian model driven by transitory and permanent monetary and real shocks. Temporary increases in the nominal interest-rate lead, in...

I investigate the effects of an increase in the nominal interest rate on inflation and output in the United States and Japan during the postwar period. I postulate a structural autoregressive model that allows for transitory and permanent nominal and real shocks. I find that nominal...
