We discuss the concept of core inflation and its relevance for policymakers and then review a variety of approaches that have been pursued for the construction of informative core measures. After illustrating some empirical patterns displayed by U.S. inflation data and discussing conceptual...

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,...

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...

This paper introduces a new decomposition of euro area headline inflation into core, cyclical, and residual components. Our new core inflation measure, the structural core inflation rate, is the expected headline inflation, conditional to medium to long-term demand and supply-side developments....

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 disaggretion of the CPI over 1990-2021, and...

This paper introduces a new decomposition of euro area headline inflation into core, cyclical and residual components. Our new core inflation measure, the structural core inflation rate, bears the interpretation of expected headline inflation, conditional to medium to long-term demand and...

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...

Do "real" assets protect against inflation? Core inflation betas of stocks are negative while energy betas are positive; currencies, commodities, and real estate also mostly hedge against energy inflation but not core. These hedging properties are reflected in the prices of inflation risks: only...

We provide theory and evidence that relative price shocks can cause aggregate inflation and act as aggregate supply shocks. Empirically, we show that exogenous positive energy price shocks have a positive impact not only on headline but also on U.S. core inflation while depressing U.S. real...

In closed or open economy models with complete markets, targeting core inflation enables monetary policy to maximize welfare by replicating the flexible price equilibrium. We analyze this result in the context of developing economies, where a large proportion of households are credit constrained...

In this paper, we investigate the use of limited-information estimators as measures of core inflation. Employing a model of asymmetric supply disturbances, with costly price adjustment, we show how the observed skewness in the cross-sectional distribution of inflation can cause substantial noise...

Decomposing inflation into core and non-core components (e.g., energy) sheds new light on the nature of inflation risk and risk premia. While stocks have insignificant exposure to headline inflation in the U.S., their core inflation betas are negative and energy betas are positive. Conventional...

Using US and EU data, the present paper investigates if the core inflation, the measure of price growth obtained excluding the more volatile items such as energy and food prices, is a good approxi- mation of the headline inflation that considers the entire bundle. Starting from mid-90s, our...

This paper studies optimal monetary policy responses in an economy featuring sectorial heterogeneity in the frequency of price adjustments. It shows that a central bank facing heterogeneous nominal rigidities is more likely to behave less aggressively than in a fully sticky economy. Hence, the...

We examine two measures of core inflation which have been proposed in recent years: the limited-influence estimators of core inflation pioneered by Bryan and Cecchetti (1994); and the Edgeworth or variance-weighted price index discussed by Diewert (1995). We compare these measures with...

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...

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...

We investigate the dynamics of core inflation in Italy, with a special focus on the period of low inflation after 2014, through the lenses of a Phillips curve framework. Composite indicators of the Italian labour and financial market are constructed and included into a Phillips curve. A number...

Inflation dynamics have been difficult to explain over the last decade. This paper explores if a more comprehensive treatment of globalization can help. CPI inflation has become more synchronized around the world since the 2008 crisis, but core and wage inflation have become less synchronized....
