LAW OF DIMINISHING MARGINAL RETURNS: A principle stating that as more and more of a variable input is combined with a fixed input in short-run production, the marginal product of the variable input eventually declines. This is THE economic principle underlying the analysis of short-run production for a firm. Among a host of other things, it offers an explanation for the upward-sloping market supply curve. How does the law of diminishing marginal returns help us understand supply? The law of supply and the upward-sloping supply curve indicate that a firm needs to receive higher prices to produce and sell larger quantities. Why do they need higher prices?

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.
