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.

MARGINAL COST AND LAW OF DIMINISHING MARGINAL RETURNS Decreasing then increasing marginal cost, reflected by a U-shaped marginal cost curve, is the result of increasing then decreasing marginal returns. In particular the decreasing marginal returns is caused by the law of diminishing marginal returns. As such, the law of diminishing marginal returns affects not only the short-run production of a firm but also the cost of short-run production. This translates into a positively-sloped supply curve for profit-maximizing competitive firms.
