Large price changes in industries affected by the COVID-19 pandemic have caused erratic fluctuations in the U.S. headline inflation rate. This paper compares alternative approaches to filtering out the transitory effects of these industry price changes and measuring the underlying or core level...

We show that in both time-dependent and state-dependent sticky price models, prices of sticky price products (i.e. whose price changes rarely) contain more information about medium term inflation developments than those of flexible price products (i.e. whose price changes frequently). We do this...

We propose a framework for consistently evaluating core inflation measures via a straightforward application of sound statistical inference principles. Under this framework, inflation measures (both headline and core) are regarded as estimators tracking the economy's true, unobserved inflation...

The standard measure of core or underlying inflation is the inflation rate excluding food and energy prices. This paper constructs an alternative measure, the weighted median inflation rate, for 38 advanced and emerging economies using subclass level disaggregation of the CPI over 1990-2021, and...
