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.
Monopolistic market structures also engage in non-price competition because they are not price takers. Due to having rather fixed market prices, leading to inelastic demand, they engage in product differentiation. Monopolistic markets engage in non-price competition because of how the market is designed where the firm dominates the market.
Duopolies sell to consumers in a competitive market where the choice of an individual consumer choice cannot affect the firm in a duopoly market, as the defining characteristic of duopolies is that decisions made by each seller are dependent on what the other competitor does. Duopolies can exist in various forms, such as Cournot, Bertrand, or ...
The market structure determines the price formation method of the market. Suppliers and Demanders (sellers and buyers) will aim to find a price that both parties can accept creating a equilibrium quantity.

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 ...
In any given market, the power structure will either be in favor of sellers or in favor of buyers. The former case is known as a seller's market; the latter is known as a buyer's market or consumer sovereignty. [22] In either case, the disadvantaged group is known as price-takers and the advantaged group known as price-setters. [23]
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 ...
It is also called oligopolistic price coordination [6] or tacit parallelism. [ 7 ] A dataset of gasoline prices of BP , Caltex , Woolworths , Coles , and Gull from Perth gathered in the years 2001 to 2015 was used to show by statistical analysis the tacit collusion between these retailers. [ 8 ]
