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.

PERFECTLY ELASTIC An elasticity alternative in which infinitesimally small changes in one variable (usually price) cause infinitely large changes in another variable (usually quantity). Quantity is infinitely responsive to price. Any change in price, no matter how small, triggers an infinite change in quantity. This characterization of elasticity is most important for the price elasticity of demand and the price elasticity of supply. Perfectly elastic is one of five elasticity alternatives. The other four are perfectly inelastic, relatively elastic, relatively inelastic, and unit elastic.
