AGGREGATE EXPENDITURES: The total expenditures on gross domestic product undertaken in a given time period by the four sectors -- household, business, government, and foreign. Expenditures made by each of these sectors are specifically labeled consumption expenditures, investment expenditures, government purchases, and net exports. Aggregate expenditures (AE) are a cornerstone in the study of macroeconomics, playing critical roles in Keynesian economics, aggregate market analysis, and to a lesser degree, monetarism.

DECREASING-COST INDUSTRY

A perfectly competitive industry with a negatively-sloped long-run industry supply curve that results because expansion of the industry causes lower production cost and resource prices. A decreasing-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 downward, which decreases the minimum efficient scale of production.
