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.
An oligopoly may engage in collusion, either tacit or overt to exercise market power and manipulate prices to control demand and revenue for a collection of firms. 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 ...
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 duopoly (from Greek δύο, duo ' two '; and πωλεῖν, polein ' to sell ') is a type of oligopoly where two firms have dominant or exclusive control over a market, and most (if not all) of the competition within that market occurs directly between them. Duopoly is the most commonly studied form of oligopoly due to its simplicity.
These functions describe each firm's optimal (profit-maximizing) quantity of output given the price firms face in the market, , the marginal cost, , and output quantity of rival firms. The functions can be thought of as describing a firm's "Best Response" to the other firm's level of output.
A special type of Oligopoly, where two firms have exclusive power and control in a market. Both companies produce the same type of product and no other company produces the same or alternative product. The goods produced are circulated in only one market, and no other company intends to enter the market. The two companies have a lot of control ...
Diagram 1 illustrates firm 1's best response function, ″ (), given the price set by firm 2. Note, M C {\displaystyle MC} in the diagram stands for marginal cost, c {\displaystyle c} . The Nash Equilibrium ( N {\displaystyle N} ) in the Bertrand model is the mutual best response; an equilibrium where neither firm has an incentive to deviate ...
Specifically, an industry is a natural monopoly if the total cost of one firm, producing the total output, is lower than the total cost of two or more firms producing the entire production. In that case, it is very probable that a company ( monopoly ) or minimal number of companies ( oligopoly ) will form, providing all or most relevant ...
