KEYNESIAN EQUILIBRIUM: The state of the macroeconomy in which aggregate expenditures are equal to aggregate output. This is illustrated using the income-expenditure model, or Keynesian cross, as the intersection of the aggregate expenditures line and the 45-degree line. The aggregate expenditures line is the summation of consumption expenditures, investment expenditures, government purchases, and net exports. The 45-degree line represents all combinations in which aggregate expenditures equal aggregate output. Keynesian equilibrium is also represented by the saving-investment, or injection-leakage, model as the intersection between the injection line (investment expenditures, government purchases, and exports) and the leakage line (saving, taxes, and imports).

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.
