The demand curve and supply curve for a good are given by Q^D = 100 - 5P and Q^S = 1.25P - 2.5. Suppose the production of this good generates a negative externality, where the external marginal cost is constant at $2. To achieve the socially optimal output level, the government wants to implement a quota. What size should the quota be?
