ENTRY BARRIER: An institutional, government, technological, or economic restriction 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.

SELLERS' MARKET

A disequilibrium condition in a competitive market that has a shortage or excess demand. Because the quantity demanded is greater than the quantity supplied, sellers have the "upper hand" when negotiating. A sellers' market also goes by the more common term of shortage. The alternative to a sellers' market is a buyers' market, which has a surplus or excess supply.
