There are eight characteristics of monopolistic competition (MC): • Companies are price setters. • Free movement of resources from one company to another. •
Product differentiation. • Many companies. •
Freedom of entry and exit. • Independent decision making. • Some degree of market power. • Buyers and sellers do not have perfect information.
Product differentiation MC companies sell products that have real or perceived non-price differences. Examples of these differences could include physical aspects of the product, location from which it sells the product or intangible aspects of the product, among others. However, the differences are not so great as to eliminate other goods as substitutes. In technical terms, the
cross price elasticity of demand between goods in such a market is large and positive. MC goods are best described as close but imperfect substitutes. The fact that there are "many companies" means that each company has a small market share. This gives each MC company the freedom to set prices without engaging in strategic decision making regarding the prices of other companies (no mutual dependence) and each company's actions effect the market negligibly. For example, a company could reduce prices and increase sales without fear that its actions will prompt retaliatory responses from competitors. The number of companies that an MC market structure will support at market equilibrium depends on factors such as fixed costs,
economies of scale, and the degree of product differentiation. For example, the greater the fixed costs, the fewer companies the market will support.
Freedom of entry and exit Like perfect competition, with monopolistic competition also, the companies can enter or exit freely. The companies will enter when the existing companies are making super-normal profits. With the entry of new companies, the supply would increase which would reduce the price and hence the existing companies will be left only with normal profits. Similarly, if the existing companies are sustaining losses, some of the marginal companies will quit. It will reduce the supply due to which price would rise and the existing companies will be left only with normal profit.
Independent decision-making Each MC company independently sets the terms of exchange for its product. The company gives no consideration to what effect its decision may have on its competitors. Market power also means that an MC company faces a downward sloping demand curve. In the long run, the demand curve is very elastic, meaning that it is sensitive to price changes, although it is not completely "flat". In the short run, economic profit is positive, but it approaches zero in the long run.
Imperfect information No other sellers or buyers have complete market information, like market demand or market supply. ==Inefficiency==
