UNDERGROUND ECONOMY: Illegal and unreported market transactions and productive activity that escape the watchful eyes of official record keepers. By most estimates, a substantial amount of productive activity takes place in the underground economy for the United States. Of course, these are only estimates because such activity, by definition, goes unreported. Were activity in the underground economy added to official activity in the "overground" economy, then gross domestic product could be boosted by as much as 25% to 50%, or more.

IMPERFECT COMPETITION

Markets or industries with two or more sellers and buyers that fail to match the criteria of perfect competition. The most noted examples of imperfect competition are the two market structures with selling-side control--monopolistic competition and oligopoly. Lesser known market structures with buying-side control--monopsonistic competition and oligopsony--are also considered as imperfect competition. Facing no competition, monopoly and monopsony are not included. Most real world markets can be considered imperfect competition.
