WELFARE ECONOMICS: A branch of economics that studies efficiency and the overall well-being of society based on alternative allocations of scarce resources. Welfare economics extends the microeconomic analysis of indifference curves to society as a whole. It is concerned with broad efficiency questions and criteria (Pareto efficiency and Kaldor-Hicks efficiency) as well as more specific efficiency issues (market failures, externalities, public goods).

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.
