PERFECT COMPETITION, SHORT-RUN PRODUCTION ANALYSIS: A perfectly competitive firm produces the profit-maximizing quantity of output that equates marginal revenue and marginal cost. This production level can be identified using total revenue and cost, marginal revenue and cost, or profit. Because a perfectly competitive firm faces a perfectly elastic demand curve, it efficiently allocates resources by equating price and marginal cost. In addition, the marginal cost curve above the average variable cost curve is the perfectly competitive firm's short-run supply curve.

PLANNING CURVE: Another term for the long-run average cost curve (LRAC). Using the name planning curve indicates that the long-run average cost curve is used to "making plans" especially concerning the desired scale of operations of a firm. That is, in the long run a firm will seek the plant size that maximizes long-run profit by equating long-run marginal cost and marginal revenue. It will then pick out the appropriate plant size off the long-run average cost with the minimum short-run average total cost.

The law of demand is one of the most important principles found in the study of economics.
