AGGREGATE EXPENDITURE EQUATION: An equation indicating that aggregate expenditures (AE) are the sum of consumption expenditures (C), investment expenditures (I), government purchases (G), and net exports (X-M), stated as: AE = C + I + G + (X-M). This equation surfaces in the Keynesian economic income-expenditure model in the form of the aggregate expenditures line. However, it's also central throughout the study of macroeconomics, including aggregate demand and the measurement of gross domestic product.

FIXED INPUT An input whose quantity cannot be changed in the time period under consideration. The relevant time period is usually termed the short run. The most common example of a fixed input is capital. The alternative to fixed input is variable input. A fixed input, such as capital, provides the "capacity" constraint for the short-run production of a firm. A variable input, such as labor, provides the means of changing short-run production. As larger quantities of a variable input are added to a fixed input, the variable input becomes less productive, which is the law of diminishing marginal returns.
