ADJUSTMENT, LONG-RUN AGGREGATE MARKET: Disequilibrium in the long-run aggregate market induces changes in the price level that restore equilibrium. If the price level is above the long-run equilibrium price level, economy-wide product market surpluses cause the price level to fall. If the price level is below the long-run equilibrium price level, economy-wide product market shortages cause the price level to rise. In both cases long-run equilibrium is restored. Price level changes induce changes in aggregate expenditures but NOT changes in real production. The reason is that long-run aggregate supply is full-employment real production, which is unaffected by the price level.

AGGREGATE EXPENDITURES LINE A graphical depiction of the relation between aggregate expenditures by the four macroeconomic sectors (household, business, government, and foreign) and the level of aggregate income or production. In Keynesian economics, the aggregate expenditures line is the essential component of the Keynesian cross analysis used to identify equilibrium income and production. Like any straight line, the aggregate expenditures line is characterized by vertical intercept, which indicates autonomous expenditures, and slope, which indicates induced expenditures. The aggregate expenditures line used in Keynesian economics is derived by adding or stacking investment, government purchases, and net exports to the consumption line.
