COMPETITION AMONG THE MANY: A market with so many buyers and sellers that none is able to influence the market price or quantity exchanged. This type of competition is the one most favored by economists (the other type is competition among the few). Compared to a three-person sprint, this is like a 10,000-entry road race. To win this race, I can't count on the other 9,999 coming up injured. To win, I may have to be the best I've ever been. I just might have to set a world record. This is the type of competition that brings out the best, most efficient use of resources.

MARGINAL REVENUE, PERFECT COMPETITION

The change in total revenue resulting from a change in the quantity of output sold. Marginal revenue indicates how much extra revenue a perfectly competitive firm 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 perfectly competitive firm equates marginal revenue and marginal cost.
