  1. A drug is being produced by competitive markets at a constant marginal cost of 10 cents per dose. The demand for the drug is Q= 1,000,000 -10,000P, where Q indicates the number of doses and P is the price per dose in cents.
  
  a. What is the market equilibrium price and quantity? Sketch your answer as well as calculate it numerically.
  
  The companies that produce this product also discharge chemical wastes as a byproduct of production. The damage to the economy due to the pollution is estimated at 1 cent per dose.
  
  b. An economist testifies that this drug, despite its value to society, is being overproduced. What price and quantity would the economist advocate instead? Sketch your answer. Calculate and illustrate in your graph the dead weight loss of the market equilibrium.
  
  c. The economist suggests that a tax should be place on every dose produced. What size tax per unit of output should be imposed? What is the economic incidence of this Piguovian tax?
  
  
  
  
  
  
  
  
  
  
  
  
  
  2. A modest sized city is currently considering ways of providing broad band internet service to its citizens which is not currently available. Based on analyses from other cities, they estimate that market demand in their city is P = 20 - .1Q, where Q is measured in thousands of households served and P is the price of monthly service in 10s of dollars. The marginal cost of supplying the service is P = 1 + .001Q.
  
  A group of city counselors believes the city should own and operate the system for the purpose of making a profit. Thus, the city would be the monopoly provider.
  
  a. If these city counselors get their way, what will be the price and output of broad band service in the city? Sketch your answer as well as calculate it numerically. What is the city’s mark-up over marginal cost?
  b. What is the price elasticity of demand at this outcome? How is this number related to the mark-up you calculated in part1?
  
  c. If instead the city instead decides to provide the service at the efficient level, what would be the price and output? Compare the monopolist vs. the efficient outcome, what is the DWL involved in allowing the city to act as a monopolist? Again, provide a sketch of your answer in addition to the calculations.
  
  d. If the city counselors who want the city to act as the broad band internet monopoly find that basically no senior citizens take advantage of service but everyone else does, what would be the profit-maximizing lower price that they could offer to the senior citizens? How many senior citizen households would now also buy the service? What is the DWL now?
  
  e. If instead of supplying broadband, the monopolist was producing a product that generated substantial pollution as a byproduct of production but was currently unregulated, would the dead weight loss you calculated in part c be as large? Why or why not? Use a new graph to illustrate your answer.
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  3. Vaccinations reduce other people’s exposure to communicable diseases. Suppose the market demand for vaccinations is Q = 100-10P where Q is millions of vaccinations and P is the price per vaccination. The market is competitive and the supply function is Q = 2P – 8.
  
  a. What is the market equilibrium? Calculate and sketch your answer. Do you think the market allocation is efficient? Why or why not? If not, what type of market failure is this? Be as precise as you can.
  
  b. Suppose the marginal external benefit of vaccinations are MEB = 8 - .15Q. What is the efficient price and quantity? Calculate and sketch your answer.
  
  c. What is the DWL of the market allocation? Calculate and Illustrate.
  
  d. What is the optimal Piguovian subsidy? What is the incidence of the subsidy?
