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.

U-SHAPED COST CURVES

The family of short-run cost curves consisting of average total cost, average variable cost, and marginal cost, all of which have U-shapes. Each is U-shaped because it begins with relatively high but falling cost for small quantities of output, reaches a minimum value, then has rising cost at large quantities of output. Although the average fixed cost curve is not U-shaped, it is occasionally included with the other three just for sake of completeness.
