Question 1:
You work for the Environmental Protection Agency - the government wants to regulate air emission from cement production.
Suppose that the cement industry is perfectly competitive.
Demand is given by: P=400-Q
Supply (MPC) is given by: P=40+Q
Marginal External Costs are given by: P =1 Q
(a) How much will the unregulated market produce?
(b) What is the socially-optimal (i.e., welfare-maximizing) price and quantity?
(c) What is the deadweight loss associated with the unregulated market?
(d) What is the Pigouvian tax that will correct the externality? Draw a diagram illustrating the solutions to (a), (b), (¢c) and how the Pigouvian tax shifts the marginal private cost curve.
(e) Now suppose that instead of the industry being perfectly competitive, the good is supplied by a monopoly. How much will the monopoly produce?
(f) Draw the diagram illustrating the (a) monopoly price and quantity, (b) socially-optimal price and quantity, and (c) the deadweight loss associated with the unregulated monopoly.
(g) Briefly explain whether it still makes sense to use a Pigouvian tax in this setting to correct the externality if a monopoly provides the good.
