Where Is Inflation Persistence Coming From?
Elevated inflation continues to be a top-of-mind preoccupation for households, businesses, and policymakers. Why has the post-pandemic inflation proved so persistent? In a Liberty Street Economics post early in 2022, we introduced a measure designed to dissect the buildup of the inflationary pressures that emerged in mid-2021 and to understand where the sources of its persistence are. This measure, that we labeled Multivariate Core Trend (MCT) inflation analyzes whether inflation is short-lived or persistent, and whether it is concentrated in particular economic sectors or broad-based.

MCT Update: Inflation Persistence Declined Significantly in April
This post presents an updated estimate of inflation persistence, following the release of personal consumption expenditure (PCE) price data for April 2023. The estimates are obtained by the Multivariate Core Trend (MCT), a model we introduced on Liberty Street Economics last year and covered most recently in a May post. The MCT is a dynamic factor model estimated on monthly data for the seventeen major sectors of the PCE price index. It decomposes each sector’s inflation as the sum of a common trend, a sector-specific trend, a common transitory shock, and a sector-specific transitory shock. The trend in PCE inflation is constructed as the sum of the common and the sector-specific trends weighted by the expenditure shares.
