Document Summary

Public goods: not a rival in consumption: you using it does not affect others" use of it, non-excludable; something of value has no price attached to it. Private decisions about consumption & production can lead to inefficiency. Role of government: public policy can raise economic well-being: difficult for private markets to provide because of the free-rider problem firms cannot prevent non-payers from consuming the good positive externality. Person who benefits from a good but avoids paying for it usually with non-excludable goods. Result: not produced, even if buyers collectively value the good more than cost of providing it. Cannot prevent free riders from using it. Role of government is to see that these resources are provided. Little incentive for firms to provide it: problem: rival in consumption each person"s use reduces other"s ability to use. Role of government: ensuring they are not overused. Important common resources: clean air and water, congested roads, fish, whales, and other wildlife.

PART A

1. In which of the following situations is the Coase theorem likely to apply? Explain.

a. The neighbor who lives below you in the apartment building loves to play old John Denver records at loud volume early in the morning. In fact, his favorite song seems to be âThank God Iâm a Country Boy.â You hate old John Denver songs and this one in particular.

b. You have just moved to Beijing and quickly discover that you are allergic to smog. It causes you great pain in breathing and limits your ability to work. Furthermore, you have medical expenses related to treatment for its health effects on you.

c. Medical research in the 1990s has revealed a specific cause of birth defects related to a certain drug prescribed for pregnant women in the 1960s (thalidomide).

d. The water in the huge underground Ogalalla aquifer in the Great Plains region of the United States is being nitrate contaminated due to agricultural fertilizer use throughout the region. As a homeowner in this region, you find that your water must be treated in order to be safe for drinking.

2. One of the most striking aspects of cities in the former Soviet Union is the poor condition of public places. Streets, parks, libraries, museums, concert halls, and public gathering places of every description are all in very poor condition, revealing years of neglect and lack of maintenance.

Explain this phenomenon in light of the definition of property rights and the transition from socialism to a market economy.

3. Suppose that the marginal benefit associated with corn production is MB = 2.5. The marginal private cost of production is MPC = 2 + 0.1Q, where Q measures bushels of corn produced in thousands. The marginal damages caused by pollution in corn production are given by MD = 0.05Q.

a. Compute the privately optimal output and the socially optimal output.

b. Compute new solutions for an increase in MB to MB = 3. Explain what has happened and why. c. Demonstrate the effects of an increase in MD to MD = 0.075 compared to the solutions in part a.

4. Policy analysts in the Department of Natural Resources have estimated that the marginal benefits from water pollution abatement are given by the function MB Â¼ 0.90 Ã 0.03A, where A is a measure of the abatement intensity. Industry experts have estimated that the marginal cost of abatement activity is MC = 0.30 + 0.09A.

a. Determine the optimal level of abatement activity.

b. Explain what happens when new technology reduces the marginal cost of abatement to MC = 0.25 + 0.06A. 5. Consider the pollution reduction mechanism known as emissions trading. a. What is the economic rationale for permitting emissions trading?

b. If the objective is to minimize the cost of emissions reductions, explain what economic principle should be followed in allocating emissions reductions between two countries.

c. Suppose the marginal cost curves for emissions reductions in countries A and B are MCA = 10 + 0.04qA and MCB = 5 + 0.02qB. What is the most efficient allocation of an emission reduction of q0 between the two countries? (Assume that the emissions reductions of the two countries must add up to the total emissions reduction: q0 = qA = qB.)

PART B

1. Which of the following do you consider pure public goods? Private goods? Why?

a. Wilderness areas

b. Satellite television

c. Medical school education

d. Public television programs

e. Automated teller machine (ATM)

2. Indicate whether each of the following statements is true, false, or uncertain, and justify your answer.

a. Efficient provision of a public good occurs at the level at which each member of society places the same value on the last unit.

b. If a good is nonrival and excludable, it will never be produced by the private sector.

c. A road is nonrival because one personâs use of it does not reduce another personâs use of it.

d. Larger communities tend to consume greater quantities of a nonrival good than smaller communities.

3. Tarzan and Jane live alone in the jungle and have trained Cheetah both to patrol the perimeter of their clearing and to harvest tropical fruits. Cheetah can collect 3 pounds of fruit an hour and currently spends 6 hours patrolling, 8 hours picking, and 10 hours sleeping.

a. What are the public and private goods in this example?

b. If Tarzan and Jane are each currently willing to give up one hour of patrol for 2 pounds of fruit, is the current allocation of Cheetahâs time Pareto efficient? Should he patrol more or less?

4. The aircraft company Airbus receives much of its funding from European governments. Airbus recently decided to build a new 550-seat mega-jetliner, with duty-free shopping courts and restaurants on board. The project has experienced production delays as well as cost overruns, and it now appears that there will be very few buyers. An industry expert says the idea from the start was ânonsenseâ

Is public sector production of aircrafts ever justified?

Explain why it could lead to the apparently ill-advised decision to build the mega-jetliner.

5. Suppose that there are only two fishermen, Zach and Jacob, 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 Zach of each additional lighthouse is 90 â Q, and the marginal benefit to Jacob is 40 â Q, where Q equals 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 Zach and Jacob if the efficient number were provided?
