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.

TOTAL COST CURVE A curve that graphically represents the relation between the total cost incurred by a firm in the short-run production of a good or service and the quantity produced. The total cost curve is a cornerstone upon which the analysis of short-run production is built. It combines all opportunity cost of production into a single curve, which can then be used with the total revenue curve to determine profit. The marginal cost curve, THE focal point for the analysis of short-run production, is derived directly from the total cost curve. The shape of the curve reflects increasing marginal returns at small quantities of output and decreasing marginal returns at larger quantities.
