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.
