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.

- A change in one of the determinants can cause:
- An increase in supply, a rightward shift, which means that for any price, for every price, sellers are willing and able to sell more of the good.

SELF CORRECTION, RECESSIONARY GAP The automatic process in which the aggregate market eliminates a recessionary gap created by a short-run equilibrium that is less than full employment through decreases in wages (and other resource prices). The self-correction mechanism is triggered by short-run resource market imbalances that are closed by long-run price flexibility. The self-correction process of the aggregate market also acts to close an inflationary gap with higher wages (and other resource prices).
