LONG-RUN MARGINAL COST: The change in the long-run total cost of producing a good or service resulting from a change in the quantity of output produced. Like all marginals, long-run marginal cost is the increment in the corresponding total. What's most notable about long-run marginal cost, however, is that we are operating in the long run. Unlike the short run, in which at least one input is fixed, there are no fixed inputs in the long run. As such, there is only variable cost. This means that long-run marginal cost is the result of changes in the cost of all inputs.

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.

[What's This?]
Today, you are likely to spend a great deal of time touring the new suburban shopping complex looking to buy either any book written by Isaac Asimov or a how-to book on building remote controlled airplanes. Be on the lookout for florescent light bulbs that hum folk songs from the sixties.
