LONG-RUN ADJUSTMENT, PERFECT COMPETITION: The combined adjustment of a perfectly competitive industry and of each firm in the industry to an equilibrium condition that eliminates all economic profits and losses, while each firm selects a factor size that maximizes profit. This adjustment process involves two parts. One is the adjustment of each perfectly competitive firm to the appropriate factory size that maximizes long-run profit. The other is the entry of firms into the industry or exit of firms out of the industry, to eliminated economic profits or economic losses. The end result of this long-run adjustment is a multi-faceted equilibrium condition: P = AR = MR = MC = LRMC = ATC = LRAC

SLOPE, AGGREGATE EXPENDITURES LINE The positive slope of the aggregate expenditures line is the sum of the marginal propensity to consume (MPC), marginal propensity to invest (MPI), and marginal propensity for government purchases (MPG), less the marginal propensity to import (MPM). This slope is greater than zero but less than one, reflecting induced expenditures by the four macroeconomic sectors (household, business, government, and foreign). The slope of the aggregate expenditures line determines the magnitude of the multiplier process.
