DOUBLE COINCIDENCE OF WANTS: The requirements of a barter exchange that each trader has want the other wants and wants what the other has. Because everyone doesn't necessarily want everything, the lack of double coincidence of wants is a major obstacle in barter exchanges, especially for complex, modern economies. While double coincidence of wants is also essential for exchanges involving money, it's such an inherent trait of money we don't think twice about it. By its very nature as a generally accepted medium of exchange, everyone WANTS money.

OLIGOPOLY, CONCENTRATION: Oligopoly is a market structure that contains a small number of relatively large firms, meaning oligopoly markets tend to be concentrated. A small number of large firms account for a majority of total output. Concentration unto itself is not necessarily bad, but it often leads to inefficient behavior, such as collusion and nonprice competition. Concentration is measured in three ways--market share, concentration ratio, Herfindahl index. See also | market share | concentration ratio | four-firm concentration ratio | eight-firm concentration ratio | Herfindahl index |

TAX WEDGE The difference between demand price and supply price that is created when a tax is imposed on a market. Placing a tax on a market disrupts what otherwise would be an equilibrium equality between demand price and supply price. A tax wedge results because the tax is included in the demand price paid by buyers but not in the supply price received by sellers. With standard demand (negative slope) and supply (positive slope) curves, the incidence of the tax (who pays) is divided between buyers and sellers.
