Many alternative measures of core, or underlying, inflation have been proposed that are based on stripping out some unwanted or excessively volatile elements from the headline rate. A potential drawback of such measures is that they are necessarily atheoretic--based largely on purely statistical...

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...

We propose a new methodology to construct core inflation which is, unlike other conventional methods, not based on ad hoc elimination/trimming of prices. The empirical results suggest that the proposed measure of core inflation is highly correlated with headline inflation and is noise free; hence...

Despite the widespread use of the term "core inflation", there is neither a widely accepted theoretical definition, nor an agreed method of measuring it. The wide range of conceptual bases is potentially confusing, particularly when the measures display different trends. This article offers an...

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...

There is no unifying framework for evaluating core inflation measures, so we propose a methodological framework to close this gap. It allows us to construct, evaluate, and rank core inflation measures by applying it to countries and regions with different characteristics, such as Chile,...
