AGGREGATE EXPENDITURE DETERMINANT: A ceteris paribus factor that affects aggregate expenditures, but which is 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.

INCREASING-COST INDUSTRY

A perfectly competitive industry with a positively-sloped long-run industry supply curve that results because expansion of the industry causes higher production cost and resource prices. An increasing-cost industry occurs because the entry of new firms, prompted by an increase in demand, causes the long-run average cost curve of each firm to shift upward, which increases the minimum efficient scale of production.
