Two Measures of Core Inflation: A Comparison

Abstract

Trimmed-mean personal consumption expenditure (PCE) inflation does not clearly dominate PCE inflation excluding food and energy in real-time forecasting of headline PCE inflation. However, trimmed-mean inflation is the superior communications and policy tool because it has been a less-biased real-time estimator of headline inflation and because it more successfully filters out headline inflation?s transitory variation, leaving only cyclical and trend components.
