Consumer Price Index Definition

The Consumer Price Index (CPI) is a measure of the overall cost of the goods and services purchased by a typical consumer (Mankiw, 2011). As the Statistical Office of the European Communities (Eurostat) states, this is an important measure of inflation in Europe and throughout the developed world (Conway, 2009). It measures the change over time in the prices of consumer goods and services acquired, used or paid for by households. Instead of the "typical consumer" concept, Eurostat refers to a "consumer basket" which is a representative set of consumed goods and services (Eurostat, 2010).
