AGGREGATE DEMAND CURVE: A graphical representation of the relation between aggregate expenditures on real production and the price level, holding all ceteris paribus aggregate demand determinants constant. The aggregate demand, or AD, curve is one side of the graphical presentation of the aggregate market. The other side is occupied by the aggregate supply curve (which is actually two curves, the long-run aggregate supply curve and the short-run aggregate supply curve). The negative slope of the aggregate demand curve captures the inverse relation between aggregate expenditures on real production and the price level. This negative slope is attributable to the interest-rate effect, real-balance effect, and net-export effect.

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.
