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 ...
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.
However, the one monopoly profit theorem is not true if customers in the monopoly good are stranded or poorly informed, or if the tied good has high fixed costs. A pure monopoly has the same economic rationality of perfectly competitive companies, i.e. to optimise a profit function given some constraints.
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 ...
When C1 < C2, Firm 1 can set the price between C1 and C2. C1 = C2 = C; This is the case of the basic Bertrand Competition which both firms have the same marginal cost. From the figure, MSS has illustrated that there is only one unique point that both firms are going to set their price. It is the pure strategy of Nash equilibrium. C1 < C2
The Lerner index measures the level of market power and monopoly power that a firm owned.The higher Lerner index indicated the more monopoly power allows a company have chance to establish prices that are higher than their marginal costs and then lead a higher monopoly price. In conclusion, a monopoly price is established by a monopolistic firm ...
Therefore, the level of market power under monopolistic competition is contingent on the degree of product differentiation. Monopolistic competition indicates that enterprises will participate in non-price competition. Monopolistic competition is defined to describe two main characteristics of a market: 1. There are many sellers in the market.
Bertrand's result is paradoxical because if the number of firms goes from one to two, the price decreases from the monopoly price to the competitive price and stays at the same level as the number of firms increases further. This is not very realistic, as in reality, markets featuring a small number of firms with market power typically charge a ...
