AE LINE: Another term for aggregate expenditure line, which is a line representing the relation between aggregate expenditures and gross domestic product used in the Keynesian cross. The aggregate expenditure line is obtained by adding investment expenditures, government purchases, and net exports to the consumption line. As such, the slope of the aggregate expenditure line is largely based on the slope of the consumption line (which is the marginal propensity to consume), with adjustments coming from the marginal propensity to invest, the marginal propensity for government purchases, and the marginal propensity to import. The intersection of the aggregate expenditures line and the 45-degree line identifies the equilibrium level of output in the Keynesian cross.

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.
