Monopolistic competition information

Monopolistic competition is a type of imperfect competition such that there are many producers competing against each other but selling products that are differentiated from one another (e.g., branding, quality) and hence not perfect substitutes. In monopolistic competition, a company takes the prices charged by its rivals as given and ignores the impact of its own prices on the prices of other companies.^[1]^[2] If this happens in the presence of a coercive government, monopolistic competition will fall into government-granted monopoly. Unlike perfect competition, the company maintains spare capacity. Models of monopolistic competition are often used to model industries. Textbook examples of industries with market structures similar to monopolistic competition include restaurants, cereals, clothing, shoes, and service industries in large cities. The "founding father" of the theory of monopolistic competition is Edward Hastings Chamberlin, who wrote a pioneering book on the subject, Theory of Monopolistic Competition (1933).^[3] Joan Robinson's book The Economics of Imperfect Competition presents a comparable theme of distinguishing perfect from imperfect competition. Further work on monopolistic competition was undertaken by Dixit and Stiglitz who created the Dixit-Stiglitz model which has proved applicable used in the sub fields of international trade theory, macroeconomics and economic geography.

Monopolistically competitive markets have the following characteristics:

There are many producers and many consumers in the market, and no business has total control over the market price.
Consumers perceive that there are non-price differences among the competitors' products.
Companies operate with the knowledge that their actions will not affect other companies' actions.
There are few barriers to entry and exit.^[4]
Producers have a degree of control over price.
The principal goal of the company is to maximise its profits.
Factor prices and technology are given.
A company is assumed to behave as if it knew its demand and cost curves with certainty.
The decision regarding price and output of any company does not affect the behaviour of other companies in a group, i.e., impact of the decision made by a single company is spread sufficiently evenly across the entire group. Thus, there is no conscious rivalry among the company.
Each company earns only normal profit in the long run.
Each company spends substantial amount on advertisement. The publicity and advertisement costs are known as selling costs.

The long-run characteristics of a monopolistically competitive market are almost the same as a perfectly competitive market. Two differences between the two are that monopolistic competition produces heterogeneous products and that monopolistic competition involves a great deal of non-price competition, which is based on subtle product differentiation. A firm making profits in the short run will nonetheless only break even in the long run because demand will decrease and average total cost will increase, meaning that in the long run, a monopolistically competitive company will make zero economic profit. This illustrates the amount of influence the company has over the market; because of brand loyalty, it can raise its prices without losing all of its customers. This means that an individual company's demand curve is downward sloping, in contrast to perfect competition, which has a perfectly elastic demand schedule.
