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.

AVERAGE TOTAL COST CURVE A curve that graphically represents the relation between average total cost incurred by a firm in the short-run product of a good or service and the quantity produced. The average total cost curve is constructed to capture the relation between average total cost and the level of output, holding other variables, like technology and resource prices, constant. The average total cost curve is one of three average curves. The other two are average variable cost curve and average fixed cost curve. A related curve is the marginal cost curve.
