ELASTIC DEMAND: Relatively small changes in demand price cause relatively larger changes in quantity demanded. Elastic demand means that changes in the quantity demanded are relatively responsive to changes in the demand price. An elastic demand has a coefficient of elasticity greater than one (the negative value is ignored). You might want to compare elastic demand to inelastic demand, elastic supply, and inelastic supply.

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.
