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).

COMMON-PROPERTY GOODS Goods characterized by rival consumption and the inability to exclude nonpayers. Common-property goods are one of four types of goods differentiated by consumption rivalry and nonpayer excludability. The other three goods are private (rival consumption and nonpayers can be excluded), public (nonrival consumption and nonpayers cannot be excluded), and near-public (nonrival consumption and nonpayers can be excluded). Nonrival consumption and the ease of excluding of nonpayers means common-property goods cannot be efficiently exchanged through markets and are often overconsumed.
