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.
