Much research studies US inflation history with a trend-cycle model with unobserved components. A key feature of this model is that the trend may be viewed as the Fed’s evolving inflation target or long-horizon expected inflation. We provide a new way to measure the slowly evolving trend and...

Phillips curves are central to discussions of inflation dynamics and monetary policy. The hybrid new Keynesian Phillips curve (NKPC) describes how past inflation, expected future inflation, and a measure of real aggregate demand drive the current inflation rate. This paper studies the...

We review single-equation methods for estimating the hybrid New Keynesian Phillips curve (NKPC) and then apply those methods to U.S. quarterly data for 1955?2007. Estimating the hybrid NKPC by the generalized method of moments yields stable coefficients with a large role for expected future...

Phillips curves are central to discussions of inflation dynamics and monetary policy. New Keynesian Phillips curves describe how past inflation, expected future inflation, and a measure of real marginal cost or an output gap drive the current inflation rate. This paper studies the (potential)...

The US economy experienced a Great Moderation sometime in the mid-1980s -- a fall in the volatility of output growth -- at the same time as a fall in both the volatility of inflation and the average rate of inflation. We put this moderation in historical perspective by comparing it to the...

We provide a new way to filter US inflation into trend and cycle components, based on extracting long-run forecasts from the Survey of Professional Forecasters. We operate the Kalman filter in reverse, beginning with observed forecasts, then estimating parameters, and then extracting the...

The Great Moderation refers to the fall in U.S. output growth volatility in the mid-1980s. At the same time, the United States experienced a moderation in inflation and lower average inflation. Using annual data since 1890, we find that an earlier, 1946 moderation in output and consumption...

Interwar macroeconomic history is a natural place to look for evidence on the correlation between output growth and inflation or unexpected inflation. We apply time-series methods to measure unexpected inflation for more than twenty countries using both retail and wholesale prices. There is a...
