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 ...
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.
The Edgeworth model shows that the oligopoly price fluctuates between the perfect competition market and the perfect monopoly, and there is no stable equilibrium. [6] Unlike the Bertrand paradox, the situation of both companies charging zero-profit prices is not an equilibrium, since either company can raise its price and generate profits.
The value of the index ranges from 1/N to 1 (where N is the number of firms in the market). Thus, the more concentrated the market is, the larger the value of the Herfindahl Index will be. [4] The table below provides an overview of price competition and intensity in the four main classes of market structure.
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 ...
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 ...
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.
The monopoly price is the for which this curve intersects the line =, while the duopoly price is given by the intersection of the curve with the steeper line =. Regardless of the shape of the curve, its intersection with u = 2 p {\displaystyle u=2p} occurs to the left of (i.e., at a lower price than) its intersection with u = p {\displaystyle u ...
