An oligopoly (from Ancient Greek ὀλίγος (olígos) 'few' and πωλέω (pōléō) 'to sell') is a market in which pricing control lies in the hands of a few sellers. [1] [2] As a result of their significant market power, firms in oligopolistic markets can influence prices through manipulating the supply function.
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 ...
The correct sequence of the market structure from most to least competitive is perfect competition, imperfect competition, oligopoly, and pure monopoly. The main criteria by which one can distinguish between different market structures are: the number and size of firms and consumers in the market, the type of goods and services being traded ...
Businesses depend on each other. Under this market structure, the differentiation of products may or may not exist. [9] The product they sell may or may not be differentiated and there are barriers to entry: natural, cost, market size or dissuasive strategies. In an oligopoly, barriers to market entry and exit are high. The major barriers are ...
Oligopoly is a market form in which a market or industry is dominated by a small number of sellers. The oldest model was the spring water duopoly of Cournot (1838) [20] in which equilibrium is determined by the duopolists reactions functions.
In microeconomics, the Bertrand–Edgeworth model of price-setting oligopoly looks at what happens when there is a homogeneous product (i.e. consumers want to buy from the cheapest seller) where there is a limit to the output of firms which are willing and able to sell at a particular price. This differs from the Bertrand competition model ...
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.
As a result, industries with high barriers to entry often contain a monopoly or oligopoly with dominant power in terms of price. This dominance allows them to charge a higher price or, if other firms join the market, to use their market power and cash flow to lower prices, beating out the new competition. [10]
