A full oligopoly is one in which a price leader is not present in the market, and where firms enjoy relatively similar market control. A partial oligopoly is one where a single firm dominates an industry through saturation of the market, producing a high percentage of total output and having large influence over market conditions.
Oligopoly is a market structure that is highly concentrated. Competition is well defined through the Cournot's model because, when there are infinite many firms in the market, the excess of price over marginal cost will approach to zero. [4] A duopoly is a special form of
Firms have partial control over the price as they are not price takers (due to differentiated products) or Price Makers (as there are many buyers and sellers). [5] Oligopoly refers to a market structure where only a small number of firms operate together control the majority of the market share. Firms are neither price takers or makers.

A group of firms that explicitly agree to affect market price or output is called a cartel , with the organization of petroleum-exporting countries ( OPEC ) being one of the most ...
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 ...
