PERFECT COMPETITION, REALISM: Perfect competition is an idealized market structure that does NOT exist in the real world. While some real world industries might come relatively close to one or two of the four key characteristics of perfect competition, none matches all four sufficiently that they can be declared PERFECTLY competitively. Some industries come close on the large number of small firms and the identical product characteristics. A few industries have relatively good, although not perfect, information about prices and technology. However, almost all industries fall far short of the perfect mobility characteristics.

KEYNESIAN MODEL A macroeconomic model based on the principles of Keynesian economics that is used to identify the equilibrium level of, and analyze disruptions to, aggregate production and income. This model identifies equilibrium aggregate production and income as the intersection of the aggregate expenditures line and the 45-degree line. The Keynesian model comes in three basic variations designated by the number of macroeconomic sectors included--two-sector, three-sector, and four sector. The Keynesian model is also commonly presented in the form of injections and leakages in addition to the standard aggregate expenditures format. This model is used to analyze several important topics and issues, including multipliers, business cycles, fiscal policy, and monetary policy.
