Using the Asymmetric Trimmed Mean as a Core Inflation Indicator

Abstract

This paper discusses the use of the trimmed mean as a core inflation indicator when the price changes distribution is fat tailed and asymmetric and computes several asymmetric trimmed means that meet all the conditions suggested in Marques et al. (2000). It turns out that the 10 per cent trimmed mean centred on the 51.5th percentile is the one with the lowest volatility and so, its use, as a core inflation indicator, is recommended.
