MC: The abbreviation for marginal cost, which is the change in total cost (or total variable cost) resulting from a change in the quantity of output produced by a firm in the short run. Marginal cost indicates how much total cost changes for a give change in the quantity of output. Because changes in total cost are matched by changes in total variable cost in the short run (remember total fixed cost is fixed), marginal cost is the change in either total cost or total variable cost. Marginal cost is found by dividing the change in total cost (or total variable cost) by the change in output.

AGGREGATE EXPENDITURES LINE

A graphical depiction of the relation between aggregate expenditures by the four macroeconomic sectors (household, business, government, and foreign) and the level of aggregate income or production. In Keynesian economics, the aggregate expenditures line is the essential component of the Keynesian cross analysis used to identify equilibrium income and production. Like any straight line, the aggregate expenditures line is characterized by vertical intercept, which indicates autonomous expenditures, and slope, which indicates induced expenditures. The aggregate expenditures line used in Keynesian economics is derived by adding or stacking investment, government purchases, and net exports to the consumption line.
