This paper proposes a new method of estimating the Taylor rule with a time-varying implicit inflation target and a time-varying natural rate of interest. The inflation target and the natural rate are modeled as random walks and are estimated using maximum likelihood and the Kalman filter. I...

This paper investigates how monetary policy can help ward off a protracted deflationary slump when policy rates are near the zero bound by studying the experience of Japan during the ""Lost Decade"" which followed the asset-price bubble collapse in the early 1990s. Estimation results based on a...

This paper investigates how monetary policy can help to avoid the liquidity trap by studying the experience of Japan. First, I analyze how the Bank of Japan conducted interest rate policy over the 1990s as the economy entered a deflationary slump. I use a new method of estimating the policy rule...

This paper analyzes the dramatic rise in U.S. inflation since 2020, which we decompose into a rise in core inflation as measured by the weighted median inflation rate and deviations of headline inflation from core. We explain the rise in core with two factors, the tightening of the labor market...
