Abstract

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 based have been subject to important structural breaks following changes to the underlying […]
