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.

IMPERFECT COMPETITION Markets or industries with two or more sellers and buyers that fail to match the criteria of perfect competition. The most noted examples of imperfect competition are the two market structures with selling-side control--monopolistic competition and oligopoly. Lesser known market structures with buying-side control--monopsonistic competition and oligopsony--are also considered as imperfect competition. Facing no competition, monopoly and monopsony are not included. Most real world markets can be considered imperfect competition.
