AGGREGATE EXPENDITURE DETERMINANT: A ceteris paribus factor that affects aggregate expenditures, but which is assumed constant when the aggregate expenditure line is constructed. Changes in any of the aggregate expenditures determinants cause the aggregate expenditure line to shift. While a wide variety of specific ceteris paribus factors can cause the aggregate expenditure line to shift, it's usually most convenient to group them into the four, broad expenditure categories -- consumption, investment, government purchases, and net exports. The reason is that changes in these expenditures are the direct cause of shifts in the aggregate expenditure line. If any determinant affects aggregate expenditures it MUST affect one of these four expenditures.

MARGINAL REVENUE CURVE, MONOPOLISTIC COMPETITION A curve that graphically represents the relation between the marginal revenue received by a monopolistically competitive firm for selling its output and the quantity of output sold. Because a monopolistically competitive firm is a price maker and faces a negatively-sloped demand curve, its marginal revenue curve is also negatively sloped and lies below its average revenue (and demand) curve. A monopolistically competitive firm maximizes profit by producing the quantity of output found at the intersection of the marginal revenue curve and marginal cost curve.
