LONG-RUN MARGINAL COST CURVE: A graphical representation of the relationship between long-run marginal cost and the quantity of output produced. Like other marginal curves, the long-run marginal cost curve follows the average-marginal rule relative to the long-run average cost curve. In all outward appearance, the long-run marginal cost curve looks very much like the short-run marginal cost, that is, it is U-shaped. However, the U-shape is attributable to returns to scale rather than increasing and decreasing marginal returns.

THREE-SECTOR AGGREGATE EXPENDITURES LINE

A graphical depiction of the relation between aggregate expenditures by the three domestic macroeconomic sectors (household, business, and government) and the level of aggregate income or production. The three-sector aggregate expenditures line combines consumption expenditures, investment expenditures, and government purchases. The slope of this aggregate expenditures line is based on the marginal propensity to consume, adjusted for marginal propensities of the other expenditures that are assumed to be induced when constructing the line. This is one of three aggregate expenditures lines based on the number of sectors included. The others are the two-sector aggregate expenditures line and the four-sector aggregate expenditures line.
