LONG-RUN ADJUSTMENT, PERFECT COMPETITION: The combined adjustment of a perfectly competitive industry and of each firm in the industry to an equilibrium condition that eliminates all economic profits and losses, while each firm selects a factor size that maximizes profit. This adjustment process involves two parts. One is the adjustment of each perfectly competitive firm to the appropriate factory size that maximizes long-run profit. The other is the entry of firms into the industry or exit of firms out of the industry, to eliminated economic profits or economic losses. The end result of this long-run adjustment is a multi-faceted equilibrium condition: P = AR = MR = MC = LRMC = ATC = LRAC

ASSUMPTIONS, KEYNESIAN ECONOMICS The macroeconomic study of Keynesian economics relies on three key assumptions--rigid prices, effective demand, and savings-investment determinants. First, rigid or inflexible prices prevent some markets from achieving equilibrium in the short run. Second, effective demand means that consumption expenditures are based on actual income, not full employment or equilibrium income. Lastly, important savings and investment determinants include income, expectations, and other influences beyond the interest rate. These three assumptions imply that the economy can achieve a short-run equilibrium at less than full-employment production.
