LONG-RUN EQUILIBRIUM, MONOPOLISTIC COMPETITION: Relative freedom of entry and exit ensures that, in the long run, every firm in a monopolistically competitive industry earns exactly a normal profit, receiving neither an economic profit, nor incurring an economic loss. This result is achieved because entry and exit affects the market supply curve, which affects the overall market price, each firm's demand curve, and the range or prices it can charge. Each firm's demand curve adjusts until the profit-maximizing price is exactly equal to average total cost (both short run and long run).

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.
