AD CURVE: The aggregate demand curve, which is 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.

PRICE LEVEL The average of the prices of goods and services produced in the aggregate economy. In a theoretical sense, the price level is the price of aggregate production. In a practical sense, the price level is commonly measured by either of two price indexes, the Consumer Price Index (CPI) or the GDP price deflator. The CPI is the price index widely publicized in the media and used by the general public. The GDP price deflator, in contrast, is less well-known, but is usually the price index of choice among economists. The inflation rate is calculated as the percentage change in the price level.
