The prоvided grаph shоws the mаrginаl private cоst (MPC) curve, the marginal social cost (MSC) curve, the marginal private benefit (MPB) curve, and the marginal social benefit (MSB) curve in the market for electric vehicles. This graph shows the market for electric vehicles, with price on the vertical axis ranging from $7 to $20, and quantity on the horizontal axis from 0 to 60. The graph includes a downward-sloping marginal private benefit (MPB) curve and a higher, downward-sloping marginal social benefit (MSB) curve. An upward-sloping marginal private cost curve, labeled MPC equals MSC, represents the marginal cost to society and private producers. Horizontal dashed lines indicate price levels at $7, $10, $13, $16, and $19, while vertical dashed lines show quantities at 21, 30, and 39. The graph illustrates the difference between private and social benefits and the socially optimal level of electric vehicle production. Use the graph to answer questions a-e. Does the graph show a negative consumption externality or a positive consumption externality? Explain. (3 points) Identify the socially optimal quantity of electric vehicles. (3 points) What is the dollar value of the marginal external benefit? (3 points) Calculate the deadweight loss in the market for electric vehicles at the market equilibrium. Show your work. (3 points) The government wants the socially optimal quantity of electric vehicles to be produced and consumed. Would the government implement a per-unit tax on producers, a lump-sum subsidy to producers, a per-unit subsidy to consumers, or a lump-sum tax on consumers? Explain. (3 points)
