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).

AGGREGATE SUPPLY SHIFTS Changes in the aggregate supply determinants shift both the short-run aggregate supply curve and the long-run aggregate supply curve. The mechanism is comparable to that for market supply determinants and market supply. There are two options--an increase in aggregate supply and a decrease in aggregate supply. An increase in resource quantity or quality or a decrease in resource price shifts one or both of the aggregate supply curves to right. A decrease in resource quantity or quality or an increase in resource price shifts one or both of the aggregate supply curves to left.
