The following diagram provides the long-run supply curve (SLR), the market demand curve (D), and the marginal cost of a negative externality (MCE). 1. At the competitive market equilibrium, the price is P = $ and the quantity is Q = 2. Draw the social marginal cost curve and label it MCS 3. The Pareto Efficient level of output is Q = 4. In the diagram below, show the dead-weight-loss from the externality as DWL 5. The optimal Pigouvian tax that would eliminate the externality would be T = per unit.
