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 .
Oligopoly: The number of enterprises is small, entry and exit from the market are restricted, product attributes are different, and the demand curve is downward sloping and relatively inelastic. Oligopolies are usually found in industries in which initial capital requirements are high and existing companies have strong foothold in market share.
A bilateral monopoly is a market structure consisting of both a monopoly (a single seller) and a monopsony (a single buyer). [1]Bilateral monopoly is a market structure that involves a single supplier and a single buyer, combining monopoly power on the selling side (i.e., single seller) and monopsony power on the buying side (i.e., single buyer).
There are four basic types of market structures in traditional economic analysis: perfect competition, monopolistic competition, oligopoly and monopoly. A monopoly is a structure in which a single supplier produces and sells a given product or service.
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.
In oligopoly theory, conjectural variation is the belief that one firm has an idea about the way its competitors may react if it varies its output or price. The firm forms a conjecture about the variation in the other firm's output that will accompany any change in its own output.
It contrasts with an oligopoly, where there are many buyers but few sellers. An oligopsony is a form of imperfect competition. The terms monopoly (one seller), monopsony (one buyer), and bilateral monopoly have a similar relationship.
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 ...
