Question
Include correctly labeled diagrams, if useful or required, in explaining your answers. A
correctly labeled diagram must have all axes and curves clearly labeled and must show
directional changes. If the question prompts you to "Calculate," you must show how you
arrived at your final answer.
Suppose a good is produced in a perfectly competitive market. In this market the marginal
social benefit (MSB) exceeds the marginal private benefit (MPB) at every quantity. The
marginal social cost (MSC) equals the marginal private cost (MPC) at every quantity.
(a) Draw a correctly labeled graph of the MSB, MPB, MSC, and MPC curves and show
each of the following.
(i) The market equilibrium quantity, labeled QM
(ii) The socially optimal quantity, labeled Qs
(iii) The deadweight loss at the market equilibrium, shaded completely
(b) Suppose the government is considering two proposals to make consumers internalize the
consumption externality.
• Proposal I: Imposing a binding price ceiling
• Proposal II: Granting a per-unit subsidy to consumers
(i) Compared to the market equilibrium in part (a), would the deadweight loss increase,
decrease, or remain the same under Proposal I? Explain.
(ii) Compared to the market equilibrium in part (a), would the quantity produced
increase, decrease, or remain the same under Proposal II? Explain.
