Imperfect competition

In economics, imperfect competition included to the situation where a characteristics of an economic market have not fulfil any the fundamental conditions of a perfectly competitive market. Imperfect competition will hit market inefficiency when it happens, resulting in market failure. Imperfect competition is a term normally used to describe the seller's position, meaning that the level of competition between sellers falls far short of the level of competition in the market under ideal conditions.

The format of a market can significantly affect the financial performance together with conduct of the firms competing within it. There is a causal relationship between structure, behavior & performance paradigm. The characteristics of market outline can be measured by evaluating the degree of seller's market concentration to defining the generation of market competition. The measure of market power subjected to the firms' ability to impact the price of a value in addition to thus, raise the market price of the proceeds or improvement above marginal cost MC. Moreover, market structure can range from perfect competition to a pure monopoly. Monopolistic competition and oligopoly competition are the extreme conditions of market structure. Perfect competition occurs when there is intense price competition, perfect competition is a market situation and competitive outcome that economists usage as a benchmark for economic welfare analysis and efficiency. In perfect competition, prices fall out closer to marginal cost when at least two of the three conditions—that there are many sellers in the market, that there is excess capacity, and that there are homogeneous products.

Intensity of price competition

The intensity of price competition is another good measure of how much leadership a firm within a market structure has over price. The Herfindahl Index helps a measure of firm concentration within a market and is the written of the squared market shares of any the firms in the market Herfindahl Index = S_i^{2, where S_i = market share of firm i . Large companies are given more weight in the index unlike the N-concentration ratio. The value of the index ranges from 1/N to 1 where N is the number of firms in the market. Thus, the more concentrated the market is, the larger the value of the Herfindahl Index will be.
