pricing by an enterprise will affect its competitors and thus affect the supply and pricing of the whole market. Oligopolies generally rely on non-price weapons, such as advertising or changes in product characteristics. Several large companies hold large market shares in industrial production, each facing a downward sloping demand, and the industry is often characterized by extensive non-price competition. The oligopoly considers price cuts to be a dangerous strategy. Businesses depend on each other. Under this market structure, the differentiation of products may or may not exist. The product they sell may or may not be differentiated and there are barriers to entry: natural, cost, market size or dissuasive strategies.

affect the profits of monopolists. The monopolist has market power, that is, it can influence the price of the good. Moreover, a monopoly is the sole provider of a good or service and thus, faces no competition in the output market. Hence, there are significant barriers to market entry, such as, patents, market size, control of some raw material. Examples of monopolies include public utilities (water, electricity) and
461:. A monopolist faces a downward sloping demand curve. Thus, as the monopolist raises its price, it sells fewer units. This suggests that when prices rise, even monopolists can drive away customers and sell fewer products. The difference between monopoly and other models is that monopolists can price their products without considering the reactions of other firms' strategic decisions.

Customers make subjective choices about what they want to buy, because they have no objective criteria to distinguish the quality of products. Location and taste are important criteria to determine whether they are consumers' special preferences.

In a monopoly market, there is only one supplier and many buyers; it is a firm with no competitors in its industry. If there is competition, it is mainly some marginal companies in the market, generally accounting for 30-40% of the market share. The decisions of marginal companies will not materially

Governments often restrict monopolies through high taxes or anti-monopoly laws as high profits obtained by monopolies may harm the interests of consumers. However, restricting the profits of monopolists may also harm the interests of consumers, because companies may create unsatisfied products that

Imperfect competition is inherent in capitalist economies. Firms are incentivised by profit, and hence undertake competitive strategies which reap the greatest revenue, by setting P > MC, at the cost of macroeconomic market efficiency. In the most extreme case of a monopoly, producers overcharge

Conversely, imperfect competition assumptions promote intervention in the international trade market. Assuming imperfect competition allows for economic modelling of policies to contain imperfectly competitive firms' market power, or for enhancing monopoly power in situations of national interest.
