Core inflation: concepts, uses and measurement

Author

Abstract

This paper reviews the concept of core inflation, focusing on the alternative interpretations of core inflation as the persistent or generalised element of inflation. The role of a core inflation measure in policy formulation, communication and accountability is also discussed. The paper also outlines and comments on alternative empirical approaches taken to measuring core inflation.
