ENTRY BARRIERS: Institutional, government, technological, or economic restrictions on the entry of firms into a market or industry. The four primary barriers to entry are: resource ownership, patents and copyrights, government restrictions, and start-up costs. Barriers to entry are a key reason for market control and the inefficiency that this generates. In particular, monopoly, oligopoly, monopsony, and oligopsony often owe their market control to assorted barriers to entry. By way of contrast, perfect competition, monopolistic competition, and monopsonistic competition have few if any barriers to entry and thus little or no market control.

EXCHANGE: The process of trading one item for another. Exchange is fundamental to the study of economics, markets, and market-oriented economies. Most exchanges in a modern, complex market-oriented economy involve a commodity on one side and a monetary payment (that is, price) on the other. In essence, a buyer gives up money and gets a good, while a seller gives up a good and gets money. See also | market | barter | price | money |
