AGGREGATE MARKET ANALYSIS: An investigation of macroeconomic phenomena, including unemployment, inflation, business cycles, and stabilization policies, using the aggregate market interaction between aggregate demand, short-run aggregate supply, and long-run aggregate supply. Aggregate market analysis, also termed AS-AD analysis, has been the primary method of investigating macroeconomic activity since the 1980s, replacing Keynesian economic analysis that was predominant for several decades. Like most economic analysis, aggregate market analysis employs comparative statics, the technique of comparing the equilibrium after a shock with the equilibrium before a shock. While the aggregate market model is usually presented as a simply graph at the introductory level, more sophisticated and more advanced analyses often involve a system of equations.

MARKET FAILURES Imperfections in the exchange process between buyers and sellers that prevent markets from efficiently allocating scarce resources. Market failures come in four varieties -- public goods, market control, externalities, and imperfect information. Market efficiency is achieved if the value of goods produced is equal to the value of foregone production. Markets fail when this efficiency condition is not achieved. Such failures can only be corrected by government intervention.
