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.

MONOPOLISTIC COMPETITION, DEMAND

The demand curve for the output produced by a monopolistically competitive firm is relatively elastic. The firm can sell a wide range of output within a relatively narrow range of prices. As a price maker, the firm has some ability (not much, but some) to control price. The demand curve is negatively sloped, but relatively elastic, because each firm produces a slightly differentiated product, but faces competition from a large number of very, very close substitutes.
