This paper proposes the use of wavelet methods to estimate U.S. core inflation. It explains wavelet methods and suggests they are ideally suited to this task. Comparisons are made with traditional CPI-based and regression-based measures for their performance in following trend inflation and predicting future inflation. Results suggest that wavelet-based measures perform better, and sometimes much better, than the traditional approaches. These results suggest that wavelet methods are a promising avenue for future research on core inflation.

Intuitively core inflation is understood as a measure of inflation where noisy price movements are avoided. This is typically achieved by either excluding or downplaying the importance of the most volatile items. However, some of those items show high persistence, and one certainly does not want to disregard persistent price changes. The non-equivalence between volatility and (the lack of) persistence implies that when one excludes volatile items relevant information is likely to be discarded. Therefore, we propose a new type of core inflation measure, one that takes simultaneously into account both volatility and persistence. The evidence shows that such measures far outperform those based on either volatility or persistence. The latter have been advocated in the literature in recent years.

The ability of central banks to differentiate between permanent & transitory price movements is critical for the conduct of monetary policy. The importance of gauging the persistence of price changes has led to the development of measures of underlying, or ¿core,¿ inflation that are designed to remove transitory price changes from aggregate inflation data. This article examines several proposed measures of core inflation -- the ex food & energy series, an ex energy series, a weighted median series, & an exponentially smoothed series -- to identify a ¿best¿ measure. Evaluates the measures¿ performance according to criteria such as ease of design, & accuracy in tracking trend inflation. Charts & tables.

The ability of central banks to differentiate between permanent and transitory price movements is critical for the conduct of monetary policy. The importance of gauging the persistence of price changes in a timely manner has led to the development of measures of underlying, or core, inflation that are designed to remove transitory price changes from aggregate inflation data. Given the usefulness of this information to policymakers, there is a surprising lack of consensus on a preferred measure of U.S. core inflation. This article examines several proposed measures of core inflation - the popular ex food and energy series, an ex energy series, a weighted median series, and an exponentially smoothed series - to identify a best measure. The authors evaluate the measures' performance according to criteria such as ease of design and accuracy in tracking trend inflation, as well as explanatory content for within-sample and out-of-sample movements in aggregate CPI and PCE inflation. The study reveals that the candidate series perform very differently across aggregate inflation measures, criteria, and sample periods. The authors therefore find no compelling evidence to focus on one particular measure of core inflation, including the series that excludes food and energy prices. They attribute their results to the design of the individual measures and the measures' inability to account for variability in the nature and sources of transitory price movements.
