Explain fully why perfectly competitive firms and monopolies maximize profits by choosing the quantity where MR = MC. Explain why the profit maximizing price of the monopoly can be higher or lower than the profit maximizing price for perfect competition.
Compare the long-run equilibrium position of a perfectly competitive firm and a monopolist.Illustrate your answer with the aid of diagrams.
Draw a perfect competition (PC) two-diagram model showing the long-run equilibrium outcome. Now imagine that a monopolist buys
up all of the PC firms and runs all of the production facilities it has purchased as one company. Relabel the "PC Market" diagram as
"Monopoly Market" and the "Representative PC Firm" diagram as "Representative Monopoly Plant".
a)
In your plant diagram, illustrate the changes in Q*, Pe, ATCE, and total profits or losses that will happen when the
monopoly buys up the representative PC firm. Explain in detail all the changes you've made to the diagram.
b)
Illustrate the monopoly market outcomes in your market diagram. Explain how these outcomes differ from the
outcomes when this was a PC market, and why they differ.
