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 higher the four-firm concentration ratio is, the less competitive the market is. When the four-firm concentration ration is higher than 60, the market can be classified as a tight oligopoly. A loose oligopoly occurs when the four-firm concentration is in the range of 40-60. [21]
Monopolistic competition exists in-between monopoly and perfect competition, as it combines elements of both market structures. Within monopolistic competition market structures all firms have the same, relatively low degree of market power; they are all price makers, rather than price takers.
The imperfectly competitive structure is quite identical to the realistic market conditions where some monopolistic competitors, monopolists, oligopolists, and duopolists exist and dominate the market conditions. The elements of Market Structure include the number and size of sellers, entry and exit barriers, nature of product, price, selling ...
The emergence of oligopoly market forms is mainly attributed to the monopoly of market competition, i.e., the market monopoly acquired by enterprises through their competitive advantages, and the administrative monopoly due to government regulations, such as when the government grants monopoly power to an enterprise in the industry through laws ...
Supply curve: in a perfectly competitive market there is a well defined supply function with a one-to-one relationship between price and quantity supplied. [25] In a monopolistic market no such supply relationship exists. A monopolist cannot trace a short-term supply curve because for a given price there is not a unique quantity supplied.
Market concentration is affected through various forces, including barriers to entry and existing competition. Market concentration ratios also allows users to more accurately determine the type of market structure they are observing, from a perfect competitive, to a monopolistic, monopoly or oligopolistic market structure.
The more usual market format is oligopoly: several firms, each of which is large enough so that a change in their price will affect the other firms' price, except for those with monopolies. When looking at oligopolies, the problem of interdependence arises.
