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.

INTERCEPT, AGGREGATE EXPENDITURES LINE The intercept of the aggregate expenditures line indicates autonomous expenditures, aggregate expenditures that do not depend on the level of income or production. This can be thought of as aggregate expenditures that the four macroeconomic sectors (household, business, government, and foreign) undertake regardless of the state of the economy. Autonomous expenditures are affected by the aggregate expenditures determinants, which cause a change in the intercept and a shift of the aggregate expenditures line.

Today, you are likely to spend a great deal of time at a going out of business sale looking to buy either a wall poster commemorating the 2000 Presidential election or a rechargeable flashlight. Be on the lookout for fairy dust that tastes like salt.
