MARGINAL COST CURVE: A curve that graphically represents the relation between marginal cost incurred by a firm in the short-run product of a good or service and the quantity of output produced. This curve is constructed to capture the relation between marginal cost and the level of output, holding other variables, like technology and resource prices, constant. The marginal cost curve is U-shaped. Marginal cost is relatively high at small quantities of output, then as production increases, declines, reaches a minimum value, then rises. This shape of the marginal cost curve is directly attributable to increasing, then decreasing marginal returns (and the law of diminishing marginal returns).

LONG RUN, MACROECONOMICS In terms of the macroeconomic analysis of the aggregate market, a period of time in which all prices, especially wages, are flexible, and are able to achieve equilibrium levels. This is one of two macroeconomic time designations; the other is the short run. Long-run wage and price flexibility means that ALL markets, including resource markets and most notably labor markets, are in equilibrium, with neither surpluses nor shortages. Wage and price flexibility and the resulting resource market equilibria are the reason for the vertical long-run aggregate supply curve.
