Suppose the factory Afro-Puffs Inc. produces wigs. As a by-product of this wig production, they also produce dangerous emissions of toxic gases (as a result of the strong glue used to hold the hair in place). The De-Lite car factory, down the road, experiences a negative externality from this production process. Suppose that the supply curve (private marginal costs) for the wig factory is X = (2/5)P - 2, and it faces a market demand of X d = 15 - P/2. The marginal damages caused by the production of wigs can be written as X = P - 1/2.
(a) Find the equilibrium price and quantity in the market for wigs.
(b) Find the socially optimal level of wigs and the corresponding price.
(c) How much should the wig factory be taxed per wig?
(a) Set PMC equal to demand and solve for P and X. X = 50/9, P = 170/9.
(b) Find SMC by adding PMC to MD. Set SMC equal to demand and solve for P and X. X =
49/11, P = 232/11.
(c) At X = 49/11, subtract PMC from SMC. Tax = 109/22.
