Four-Firm Concentration Ratio
Definition of the Four- Firm Focus Ratio This can be one of the most common concentration proportions. The four-firm concentration ratio is commonly used to indicate the amount to which a market is oligopolistic and the magnitude of industry control kept by the several largest organizations in the industry.

Having an industry slipping between 0 to 50% is commonly interpreted as an industry with low concentration rate; the main description of this focus is that it is a very competitive market also known as monopolistic competition. Monopolistic competition is a industry structure seen as a a large number of companies which are identical but do not sell the same products, family member freedom of entry, into and exit out of the market, and extensive knowledge of rates and technology. Monopolistic competition approximates the majority of the characteristics of perfect competition, but declines short of achieving the ideal benchmark, that is ideal competition. What long-run modifications would you expect following this enhancements made on demand? Firstly, since a change in demand came about, it is important to clarify the partnership between the monopolistic competition and demand. The demand curve pertaining to the output created by a monopolistically competitive company is relatively flexible. The company can sell a variety of output within a relatively filter range of rates. Demand is actually elastic in monopolistic competition because every single firm encounters competition from a large number of very, very close substitutes. However , require is not really perfectly stretchy (as in perfect competition) because the outcome of each organization is a bit...
