Given the highly kurtotic and positively skewed characteristics of cross-sectional distribution of price, asymmetric trimmed-mean is the best approach in extracting the statistical medium-term trend of inflation. This paper uses asymmetric trimmed-mean approach to measure core inflation in...

This paper assesses the performance of the core inflation measures calculated by the Brazilian Central Bank (BCB). The evidence shows that they do not meet some key statistical criteria that a good core inflation should have: unbiasedness and the ability to forecast inflation. That performance...

This paper explores the concept of underlying inflation and the properties of various measures of underlying inflation in the Australian context. Underlying inflation measures are routinely calculated and monitored by central banks in many countries, including the Reserve Bank of Australia....

This paper examines robust estimators of core inflation for Belgian historical CPI data, and for euro area Harmonised Indices of Consumer Prices. Evidence of fat tails in the cross-sections of price changes is provided by traditional measures, as well as by a robust measure of the tail weights...

The paper briefly reviews the accomplishments of the Ottawa Group on the occasion of its tenth meeting and then goes on to list ten problem areas in price measurement that have not been completely resolved and hence should be a focus of future meetings. The ten problem areas are: (1) the...

The paper studies a possibility to construct a price index (“core inflation” index) for Russia, which is more appropriate for assessing monetary policy than consumer price index. The index is derived by applying to Russian data trimmed mean method, which explores cross-sectional dimension of...

Policymakers are interested in the general trend of inflation. Headline inflation is subject to different shocks and contains noise due to the heterogeneity inherit in it. Therefore, core inflation measures, which are better capable of indicating general trend, are developed. Atuk and Özmen...

This paper uses a restricted factor model to estimate the HICP index excluding relative prices changes. The index thus obtained, hereinafter referred to as pure inflation, demonstrates stronger relationship to the central bank instrument (short-term interest rate) than the HICP index and...

Measures of core inflation convey critical information about an economy. They have a direct effect on the policy-making process, particularly in inflation-targeting countries, and are utilized in forecasting and modelling exercises. In South a Africa the prices indices on which inflation is...

In this study, we discuss the overall performance of different core inflation measures for Turkey. We first describe and derive the core measures based on exclusion, statistical and model-based methods. We then compare their performances during the entire sample period of January 2003 –...
