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.

A curve that graphically represents the relation between marginal factor cost incurred by a firm for hiring an input and the quantity of input employed. A profit-maximizing firm hires the quantity of input found at the intersection of the marginal factor cost curve and marginal revenue product curve. The marginal factor cost curve for a firm with no market control is horizontal. The marginal factor cost curve for a firm with market control is positively sloped and lies above the average factor cost curve.
