A

Suppose the external marginal cost of pollution is MCexternal = 5Q and the internal marginal cost is MCinternal = 10Q. Further, assume the inverse demand for the product, Q, is given by P = 90 - Q. a. What is the socially efficient level of output? b. How much output would a competitive industry produce? c. How much output would a monopoly produce? d. Discuss three ways government can induce firms to produce the socially efficient level of output.

a. The socially efficient level of output is such that P = MCexternal + MCinternal. Given these cost and demand conditions, this implies 90 - Q = 15Q, or Q = 5.625 units.

b. A competitive industry would produce such that P = MCinternal, which in this case reduces to 90 - Q = 10Q. Solving for Q yields a competitive industry output of Q = 8.18 units.

c. A monopoly would produce such that MR = MCinternal. In this case, this condition implies 90 - 2Q = 10Q. Solving for Q yields the monopoly output of 7.5 units.

d. The government could sell permits to the firms to allow them to emit negative externalities, or impose a production tax on the firms in the industry. Notice that, since the monopoly is closest to the socially efficient level of output, a lower tax would be required for it than for the competitive industry.
