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.

TWO-SECTOR KEYNESIAN MODEL

A Keynesian model of the macroeconomy that includes the two private sectors, the household sector and the business sector. This Keynesian model variation, often termed the basic Keynesian model or the private sector Keynesian model, captures the interaction between induced consumption expenditures and autonomous investment expenditures. This model is commonly used to illustrate the basic workings of Keynesian economics, including equilibrium, disequilibrium, and the multiplier. Equilibrium is identified as the intersection between the C + I line and the 45-degree line. Two related variations are the three-sector Keynesian model and the four-sector Keynesian model.
