MARGINAL REVENUE CURVE, PERFECT COMPETITION: A curve that graphically represents the relation between the marginal revenue received by a perfectly competitive firm for selling its output and the quantity of output sold. Because a perfectly competitive firm is a price taker and faces a horizontal demand curve, its marginal revenue curve is also horizontal and coincides with its average revenue (and demand) curve. A perfectly competitive firm maximizes profit by producing the quantity of output found at the intersection of the marginal revenue curve and marginal cost curve.

INFLATIONARY EXPECTATIONS, AGGREGATE DEMAND DETERMINANT

One of several specific aggregate demand determinants assumed constant when the aggregate demand curve is constructed, and that shifts the aggregate demand curve when it changes. An increase in the inflationary expectations causes an increase (rightward shift) of the aggregate curve. A decrease in the inflationary expectations causes a decrease (leftward shift) of the aggregate curve. Other notable aggregate demand determinants include interest rates, federal deficit, and the money supply.
