20. 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 Xd=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.(i) How much should the wig factory be taxed per wig?

21. Consider the following net benefits (measured in billions of dollars) that will result from the passage of two legislative bills, X and Y:

(a) Identify the logrolling opportunity present in this situation.(b) Identify the potential gains to voters.(c) Explain why logrolling is efficiency enhancing.Ans: (a) On their own, neither issue X nor Y will pass. Both will be voted down by votes of 2-1. If person A trades a vote with B, then both issues will pass by 2-1 votes.(b) With both issues passed, overall utility for person A is 3. For person B, overall utility is 4. For person C, overall utility is 5.(c) With issue X passed, society is benefited because it had a total benefit to society of 3. Logrolling also allowed issue Y to pass, though it shouldnt have since its total benefit to society is 1.

Ans: (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.

22. Suppose that there are only two fishermen, Ali and Ahmet, who fish along a certain coast. They would each benefit if lighthouses were built along the coast where they fish. The marginal cost of building each additional lighthouse is $100. The marginal benefit to Ali of each additional lighthouse is 90-Q, and the marginal benefit to Jacob is 40-Q, where Q is the number of lighthouses.a) Explain why we might not expect to find the efficient number of lighthouses along this coast.b) What is the efficient number of lighthouses?What would be the net benefits to Ali and Ahmet if efficient number were provided?

Ans: a) since the marginal cost (100) is greater than marginal benefit(when Q=0) for each individual. When it is left to Ali and Ahmet, they wont demand any lighthouse.b) For public goods efficient quantity is found when market demand equals market supply. To find market demand we add individual demands vertically. (90-Q+40-Q=130-2Q) Then equalize this with MC=100 130-2Q=100Q*=15

When Q=15 Net benefit to Ali is and Veli ia consumer surplus(area of the triangle under market demand line and above MC. (130-100)*15/2 = 225
