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).

In addition, the marginal cost curve above the average variable cost curve is the perfectly competitive firm's short-run supply curve.
