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.

EFFECTIVE DEMAND A key conceptual notion of Keynesian economics stipulating that the aggregate expenditures on real production is based on existing or actual income rather than the income that would be generated with full employment of resources. Effective demand is embodied in the aggregate expenditures line, which has a positive slope, but a slope of less than one. This concept was proposed by Thomas Robert Malthus in the early 1800s as a counter argument to Say's law found in classical economics and then found new life when John Maynard Keynes developed his theory in the 1930s.
