VARIABLE INPUT: An input whose quantity can be changed in the time period under consideration. This should be immediately compared and contrasted with fixed input. The most common example of a variable input is labor. A variable input provides the extra inputs that a firm needs to expand short-run production. In contrast, a fixed input, like capital, provides the capacity constraint in production. As larger quantities of a variable input, like labor, are added to a fixed input like capital, the variable input becomes less productive. This is, by the way, the law of diminishing marginal returns.

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 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.

AGGREGATE DEMAND The total real expenditures on final goods and services produced in the domestic economy that buyers are willing and able to undertake at different price levels, during a given time period (usually a year). Aggregate demand, usually abbreviated AD, is an inverse relation between price level and aggregate expenditures. This is one half of the AS-AD (aggregate market) analysis. The other half is aggregate supply. Aggregate demand consists of four aggregate expenditures--consumption expenditures, investment expenditures, government purchases, and net exports--made by the four macroeconomic sectors--household, business, government, and foreign.
