2. "The short-run supply curve of a perfectly competitive firm is the firm's marginal cost curve."
Carefully explain the two exceptions to the statement above.
3. Suppose that, in a perfectly competitive market at the profit-maximizing quantity, the market price is greater than average total cost. Carefully explain what will happen to the number of firms, the market supply, and the price of the good as we move from the short run to the long run.
4.Suppose a monopolist faces the following demand curve:
P = 596 - 6Q. Marginal cost of production is constant and equal to $20, and there are no fixed costs.
a) What is the monopolist's profit-maximizing level of output?
b) What price will the profit-maximizing monopolist charge?
c) How much profit will the monopolist make if she maximizes her profit?
d) What would be the value of consumer surplus if the market were perfectly competitive?
e) What is the value of the deadweight loss when the market is a monopoly?
