BARRIER TO ENTRY: 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.

PERFECT COMPETITION, REVENUE DIVISION: The marginal approach to analyzing a perfectly competitive firm's short-run profit maximizing production decision can be used to identify the division of total revenue among variable cost, fixed cost, and economic profit. The U-shaped cost curves used in this analysis provide all of the information needed on the cost side of the firm's decision. The demand curve facing the firm (which is also the firm's average revenue and marginal revenue curves) provides all of the information needed on the revenue side.

MARGINAL REVENUE, MONOPOLY The change in total revenue resulting from a change in the quantity of output sold. Marginal revenue indicates how much extra revenue a monopoly receives for selling an extra unit of output. It is found by dividing the change in total revenue by the change in the quantity of output. Marginal revenue is the slope of the total revenue curve and is one of two revenue concepts derived from total revenue. The other is average revenue. To maximize profit, a monopoly equates marginal revenue and marginal cost.
