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).

SELF CORRECTION, RECESSIONARY GAP The automatic process in which the aggregate market eliminates a recessionary gap created by a short-run equilibrium that is less than full employment through decreases in wages (and other resource prices). The self-correction mechanism is triggered by short-run resource market imbalances that are closed by long-run price flexibility. The self-correction process of the aggregate market also acts to close an inflationary gap with higher wages (and other resource prices).

Today, you are likely to spend a great deal of time lost in your local discount super center trying to buy either several magazines on fashion design or a package of 3 by 5 index cards, the ones without lines. Be on the lookout for small children selling products door-to-door.
