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.

WAGES, AGGREGATE SUPPLY DETERMINANT One of several specific aggregate supply determinants assumed constant when the short-run aggregate supply curve is constructed, and that shifts the short-run aggregate supply curve when it changes. An increase in the wages causes a decrease (leftward shift) of the short-run aggregate supply curve. A decrease in the wages causes an increase (rightward shift) of the short-run aggregate supply curve. Other notable aggregate supply determinants include the technology, energy prices, and the capital stock. Wages are an example of a resource price aggregate supply determinant.
