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.

In general, total revenue is the price times quantity--the price received for selling a good times the quantity of the good sold at that price. For a perfectly competitive firm, which receives a single unchanging price for all output sold, the calculation is relatively easy. Two other revenue measures directly related to total revenue are average revenue and marginal revenue. Total revenue is often depicted as a total revenue curve.
