REALISM OF PERFECT COMPETITION: 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 a one or two of the four key characteristics of perfect competition, none matches all four sufficiently that we can declare a perfectly competitively industry. 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.

MARKET FAILURE: A condition in which a market does not efficiently allocate resources to achieve the greatest possible consumer satisfaction. The four main market failures are--(1) public good, (2) market control, (3) externality, and (4) imperfect information. In each case, a market acting without any government imposed direction, does not direct an efficient amount of our resources into the production, distribution, or consumption of the good. See also | market | fifth rule of imperfection | sixth rule of ignorance | public good | market control | externalities | production | consumption | information | pollution | regulation |

Concentration is measured in three ways--market share, concentration ratio, Herfindahl index.
