Monopoly and Marginal Cost - amazonia.fiocruz.br

The fact that price Moonpoly monopoly exceeds marginal cost suggests that the monopoly solution violates the basic condition for economic efficiency, that the price system must confront decision makers with all of the costs and all of the benefits of their choices. Efficiency requires Monopoly and Marginal Cost consumers confront prices that equal marginal costs. To contrast the efficiency of the perfectly competitive outcome with the inefficiency of the monopoly outcome, imagine a perfectly competitive industry whose solution is depicted in Figure The short-run industry supply curve is the summation of individual marginal cost curves; it may be regarded as Monoploy marginal cost curve for the industry. A perfectly competitive industry achieves equilibrium at point C, at price P c and quantity Q c.

Given market demand and marginal revenue, we can compare the behavior of a monopoly to that of a perfectly competitive industry. The marginal cost curve may be thought of as the supply curve of a perfectly competitive industry. The perfectly competitive industry produces quantity Q c and sells the output Monopoly and Marginal Cost price P c.

The monopolist restricts output to Q m and raises the price to P m. Reorganizing a perfectly competitive industry as a monopoly results in a deadweight loss to society given by the shaded area GRC. It also transfers a portion of the consumer Monopolly earned in the competitive case to the monopoly firm.

Monopoly and Efficiency

Now, suppose that all the firms in the industry merge and a https://amazonia.fiocruz.br/scdp/essay/is-lafayette-a-hidden-ivy/theater-at-the-mgm-grand-hotel.php restriction prohibits entry by any new firms. Our perfectly competitive industry is now a monopoly.

Assume the monopoly continues to have the same marginal cost and demand curves that the competitive industry did. The monopoly firm faces the same market Monopoly and Marginal Cost curve, from which it derives its marginal revenue curve. It maximizes profit at output Q m and charges price P m. Output is lower and price higher than in the competitive solution. Society would gain by moving from the monopoly solution at Q m to the competitive solution at Q c.

The benefit to consumers would be given by the area under the demand curve between Q m and Q c ; it is the area Q m RC Q c. An increase in output, of course, has a cost.

Because the marginal cost curve measures the cost of each additional unit, we can think of the area under the marginal cost curve over some range of output as measuring the total cost of that output. Thus, the total cost of increasing output from Q m to Q c is the area under the marginal cost curve over that range—the area Q m GC Q c. Subtracting this cost from the benefit gives us the net gain of moving from the monopoly to the competitive solution; it is the shaded area GRC. That is the potential gain from moving to the efficient solution. The area GRC is a deadweight loss. Monopoly and Efficiency The fact that price in monopoly exceeds marginal cost suggests that the monopoly solution violates the basic condition for economic Respiratory Syncytial Virus, that the price system must confront decision makers with all of the costs and all of the benefits of their choices.
