INDEX: A measure of the relative average of a group of items compared to a given base value. Index measures are commonly used in economics to combine and compare diverse measures. One common type of index measure is for prices, such as the Consumer Price Index and the Dow Jones Industrial Average of corporate stock prices. Another noted type of index measure is to track macroeconomic activity, especially the index leading economic indicators. Indexes are usually weighted averages rather than simple arithmetic means that are measured relative to a base value or period. The Consumer Price Index, for example, measures the prices of consumer good, weighted by the quantities purchased. The value of a given period is then stated relative to a base year value, which generates a pure, "unitless" number in the range of 100 (give or take).

ELASTICITY DETERMINANTS Three factors that affect the numerical value of the price elasticity of demand and the price elasticity of supply--availability of substitutes, time period of analysis, and proportion of budget. The price elasticities of demand and/or supply for a good can change if these determinants change. The first two determinants are important to both price elasticity of demand and price elasticity of supply, while the third relates specifically to the price elasticity of demand.
