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.

KEYNESIAN AGGREGATE SUPPLY CURVE An aggregate supply curve--a graphical representation of the relation between real production and the price level--that reflects the basic principles of Keynesian economics. The Keynesian aggregate supply curve actually comes in two versions. The basic version is reverse-L shaped, with a horizontal segment connected to a vertical segment at a sharp corner. The modified version is also reverse-L shaped, but the vertical and horizontal segments have positive slopes and connecting corner is rounded. An alternative is the classical aggregate supply curve.
