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.
