ELASTICITY: The relative response of one variable to changes in another variable. The phrase "relative response" is best interpreted as the percentage change. For example, the price elasticity of demand, one of the more important applications of this concept in economics, is the percentage change in quantity demanded measured against the percentage change in price. Other notable economic elasticities are the price elasticity of supply, income elasticity of demand, and cross elasticity of demand.

PRICE INDEX A measure of the average of a group of prices calculated as a ratio to prices in a given time period (that is, a base year). A price index is primarily used to compare relative prices, or changes in the group prices over time. Such an index is a handy indicator of overall price trends. Two common price indexes that surface in the study of macroeconomics are the Consumer Price Index (CPI) and the GDP price deflator. Both are used to indicate the macroeconomy's average price level and to estimate the inflation rate. The Dow Jones Industrial Average (the Dow), Standard & Poor's 500, and the NASDAQ are well-known indexes of stock market prices.
