AGGREGATE EXPENDITURE LINE: 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-MARGINAL RELATION A mathematical connection between a marginal value and the corresponding total value stating that the marginal IS the slope of the total curve. This mathematical relation between total and marginal surfaces throughout the study of economics, especially utility (total utility and marginal utility), production (total product and marginal product), cost (total cost and marginal cost), and revenue (total revenue and marginal revenue). A related mathematical relation exists between a marginal value and the corresponding average value.
