Part 1: Negative Externalities- Use the graph P to the right to answer the questions. $50 1. Identify the equilibrium price and quantity produced by the unregulated market. $45 MPC $40 2. Assume that each unit of the good generates $20 of external costs. Draw a $35 marginal social cost (MSC) curve and identify $30 the socially optimal price and quantity. $25 3. At the quantity of 5, identify and calculate $20 the area of deadweight loss. $15 4. Calculate the deadweight loss if the $10 government places a $20 per unit tax on the $5 good? MSB 5. Assume instead that each unit of the good 2 3 4 5 6 7 8 9 10 Q generates $30 of external costs.
