AGGREGATE EXPENDITURE DETERMINANTS: An assortment of ceteris paribus factors that affect aggregate expenditures, but which are assumed constant when the aggregate expenditure line is constructed. Changes in any of the aggregate expenditures determinants cause the aggregate expenditure line to shift. While a wide variety of specific ceteris paribus factors can cause the aggregate expenditure line to shift, it's usually most convenient to group them into the four, broad expenditure categories -- consumption, investment, government purchases, and net exports. The reason is that changes in these expenditures are the direct cause of shifts in the aggregate expenditure line. If any determinant affects aggregate expenditures it MUST affect one of these four expenditures.

GOVERNMENT PURCHASES LINE A graphical depiction of the relation between government purchases by the government sector and the economy's aggregate level of income or production. This relation plays a key role in the study of Keynesian economics. A government purchases line is characterized by vertical intercept, which indicates autonomous government purchases, and slope, which is the marginal propensity for government purchases and indicates induced government purchases. The aggregate expenditures line used in Keynesian economics is derived by adding or stacking the government purchases line onto the consumption line, as well as investment expenditures and net exports.
