SHORT-RUN SUPPLY CURVE: For a perfectly competitive firm, the marginal cost curve that lies above the average variable cost curve. This segment of the marginal cost guides a perfectly competitive firm's profit maximizing production as it equates price to marginal cost. Because the marginal cost curve is positively sloped (due to the law of diminishing marginal returns), each firm's supply curve and the market supply curve are also positively sloped. The law of diminishing marginal returns thus provides an explanation for the law of supply. However, this only works for firms with NO market control. Monopoly, monopolistic competition, and oligopoly, with market control, do not achieve the same result.

MARGINAL REVENUE CURVE, PERFECT COMPETITION A curve that graphically represents the relation between the marginal revenue received by a perfectly competitive firm for selling its output and the quantity of output sold. Because a perfectly competitive firm is a price taker and faces a horizontal demand curve, its marginal revenue curve is also horizontal and coincides with its average revenue (and demand) curve. A perfectly competitive firm maximizes profit by producing the quantity of output found at the intersection of the marginal revenue curve and marginal cost curve.
