AGGREGATE EXPENDITURES: The total expenditures on gross domestic product undertaken in a given time period by the four sectors -- household, business, government, and foreign. Expenditures made by each of these sectors are specifically labeled consumption expenditures, investment expenditures, government purchases, and net exports. Aggregate expenditures (AE) are a cornerstone in the study of macroeconomics, playing critical roles in Keynesian economics, aggregate market analysis, and to a lesser degree, monetarism.

OLIGOPOLISTIC BEHAVIOR: Oligopolistic industries are nothing if not diverse. Some sell identical products, others differentiated products. Some have three or four firms of nearly equal size, others have one large dominate firm (a clear industry leader) and a handful of smaller firms (that follow the leader). Whatever products they may sell, and however they may be organized, oligopolistic industries share several behavioral tendencies, including (1) interdependence, (2) rigid prices, (3) nonprice competition, (4) mergers, and (5) collusion. In other words, each oligopolistic firm keeps a close eye on the decisions made by other firms in the industry (interdependence), are reluctant to change prices (rigid prices), but instead try to attract the competitors customers using incentives other than prices (nonprice competition), and when they get tired of competing with their competitors they are inclined to cooperate either legally (mergers) or illegally (collusion).

VALUE IN USE

The satisfaction of wants and needs provided by the direct consumption of goods and services. Acquiring value from the use of goods and services is really the ultimate goal of economic activity. It is the final step in the production, allocation, and consumption activities that are undertaken to address the fundamental problem of scarcity. Value in use should be contrasted with the similar phrase, value in exchange.
