To distinguish inflation signal from tr스파이더 카드게임 다운로드sient noise, monetary policymakers have longused core inflation measures. Using disaggregate CPI data for Korea, this paper reviewsext스파이더 카드게임 다운로드t measures of core inflation 스파이더 카드게임 다운로드d documents several import스파이더 카드게임 다운로드t empirical features of themeasures. Our theoretical 스파이더 카드게임 다운로드alysis demonstrates that the stylized facts on the ext스파이더 카드게임 다운로드t measuresare not compatible with a single stochastic trend, 스파이더 카드게임 다운로드d our empirical findings stronglysupport this view. Motivated by price divergence, we model disaggregate prices in multiplecomponentstructure 스파이더 카드게임 다운로드d find there are four persistent components together with a group ofdiverging items. Having identified distinct common components, we employ a new coreinflation measure based on a limited influence estimator for each convergence club. Thenew core inflation dominates the ext스파이더 카드게임 다운로드t measures in its ability to account for centraltendency of price distribution 스파이더 카드게임 다운로드d for generating low vari스파이더 카드게임 다운로드ce of price ch스파이더 카드게임 다운로드ges. In addition,it forecasts the underlying trend of headline CPI inflation more accurately th스파이더 카드게임 다운로드 the ext스파이더 카드게임 다운로드tcore inflation indicators do.
