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.

AMERICAN ECONOMIC ASSOCIATION A formal organization of professional economists that promotes economic research, organizes annual meetings and conferences, and maintains a list of publications in several economics subjects. The American Economic Association (AEA) was originally organized by a small group interested in economics at a meeting in 1888 in Saratoga, New York. However, as interest in the subject grew, it officially incorporated in 1923. Although the AEA contained only a small number of members in the beginning, today the membership is approximately 18,000. In addition, about 4,600 libraries, institutions, and firms subscribe to the quarterly publications of the AEA.
