AE LINE: Another term for aggregate expenditure line, which is 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 surplus exists if the quantity demanded is less than the quantity supplied at the current market price.- A surplus exists if the market price is 70 cents.
- The quantity demanded is 200 tapes and the quantity supplied is 600 tapes, giving a surplus of 400 tapes.
- This surplus induces the price to decline down to the equilibrium level of 50 cents

CONSUMER CONFIDENCE, AGGREGATE EXPENDITURES DETERMINANT One of several specific aggregate expenditures determinants assumed constant when the aggregate expenditures line is constructed, and that shifts the aggregate expenditures line when it changes. An increase in consumer confidence causes an increase (upward shift) of the aggregate expenditures line. A decrease in consumer confidence causes a decrease (downward shift) of the aggregate expenditures line. Other notable aggregate expenditures determinants include interest rates, federal deficit, inflationary expectations, and exchange rates.
