PLANNING PERIOD: The period of time in which a firm selects the profit-maximizing plant size in the long run when all inputs, especially capital, are variable. This is, in other words, another term for the long run, but applied to the adjustment using the long-run average cost curve.

MARGINAL COST The change in total cost (or total variable cost) resulting from a change in the quantity of output produced by a firm in the short run. Marginal cost (MC) indicates how much total cost changes for a given change in the quantity of output. Because changes in total cost are matched by changes in total variable cost in the short run (total fixed cost is fixed), marginal cost is the change in either total cost or total variable cost. It is found by dividing the change in total cost (or total variable cost) by the change in output. Marginal cost is one of four cost concepts used in short-run production analysis. The other three are average total cost, average fixed cost, and average variable cost.
