PRICE CONTROLS: Government intervention in markets in which legal restrictions are placed on the prices charged. The two basic types of price controls are price ceilings and price floors. Price ceilings are maximum prices set below the equilibrium price. Price floors are minimum prices set above the equilibrium price. Price controls imposed on an otherwise efficient and competitive market create imbalances (shortages or surpluses) which cause inefficiency. However, imposing price controls on a market that fails to achieve efficiency (due to market control, externalities, or imperfect information) can actual improve efficiency. Price controls have also be used economy-wide in an attempt to reduce inflation.

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.
