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).

BALANCED-BUDGET MULTIPLIER A measure of the change in aggregate production caused by equal changes in government purchases and taxes. The balanced-budget multiplier is equal to one, meaning that the multiplier effect of a change in taxes offsets all but the initial production triggered by the change in government purchases. This multiplier is the combination of the expenditures multiplier, which measures the change in aggregate production caused by changes in an autonomous aggregate expenditure, and the tax multiplier which measures the change in aggregate production caused by changes in taxes.
