Abstract

Inflation measurement is the process whereby changes in the prices of individual goods and services are combined to yield a measure of general price change. This article discusses the conceptual framework for thinking about inflation measurement and considers practical issues associated with determining an inflation measure’s scope; with measuring individual prices; and with combining these individual prices into a measure of aggregate inflation. We also discuss the concept of ‘core inflation’ and summarize the implications of inflation measurement for economic theory and policy.
