AGGREGATE EXPENDITURES 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.

DEMAND ELASTICITY AND TOTAL EXPENDITURE The notion that price-induced changes in total expenditure (price times quantity) depend on the relative price elasticity of demand. If demand is relatively elastic, then changes in price cause total expenditure to change in the opposite direction. If demand is relatively inelastic, then changes in price cause total expenditure to change in the same direction. If demand is unit elastic, then changes in price do not cause any change in total expenditure.
