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.

PERFECT COMPETITION, EFFICIENCY Perfect competition is an idealized market structure that achieves an efficient allocation of resources. This efficiency is achieved because the profit-maximizing quantity of output produced by a perfectly competitive firm results in the equality between price and marginal cost. In the short run, this involves the equality between price and short-run marginal cost. In the long run, this is seen with the equality between price and long-run marginal cost at the minimum efficient scale of production.
