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.

NET-EXPORT EFFECT A change in aggregate expenditures on real production, especially net exports from the foreign sector, that results because a change in the price level alters the relative prices of exports and imports. The net-export effect, also termed the international-substitution effect, is one of three effects underlying the negative slope of the aggregate demand curve associated with a movement along the aggregate demand curve and a change in aggregate expenditures. The other two are real-balance effect and interest-rate effect. The net-export effect is somewhat analogous to the substitution effect underlying the negative slope of the market demand curve.
