LRAC CURVE: The common abbreviation for the long-run average cost curve, which is a curve depicting the per unit cost of producing a good or service in the long run when all inputs are variable. The long-run average cost curve can be derived in two ways. On is to plot long-run average cost, which is, long-run total cost divided by the quantity of output produced. at different output levels. The more common method, however, is as an envelope of an infinite number of short-run average total cost curves. Such an envelope is base on identifying the point on each short-run average total cost curve that provides the lowest possible average cost for each quantity of output. The long-run average cost curve is U-shaped, reflecting economies of scale (or increasing returns to scale) when negatively-sloped and diseconomies of scale (or decreasing returns to scale) when positively sloped. The minimum point (or range) on the LRAC curve is the minimum efficient scale.

MARGINAL COST AND MARGINAL PRODUCT The U-shape of the marginal cost curve is closely related to the hump-shape of the marginal product curve. The increasing portion of the marginal product curve corresponds with the decreasing portion of the marginal cost curve. The decreasing portion of the marginal product curve corresponds with the increasing portion of the marginal cost curve. The peak of the marginal product curve corresponds with the minimum of the marginal cost curve.
