Suppose a city releases 16 million gallons of raw sewage into a nearby lake. Table 12.8 shows the total costs of cleaning up the sewage to different levels, together with the total benefits of doing so. (Benefits include environmental, recreational, health, and industrial benefits.) Using the information in Table 12.8, calculate the marginal costs and marginal benefits of reducing sewage emissions for this city. See Production, Costs and Industry Structure if you need a refresher on how to calculate marginal costs. What is the optimal level of sewage for this city? Why not just pass a law that films can emit zero sewage? After all, the total benefits of zero emissions exceed the total costs.
What is a marketable permit and what incentive does it provide for a firm to account for external costs?
An emissions tax on a quantity of emissions from a film is not a command-and-control approach to reducing pollution. Why?
What is the free rider problem?
In a market without environmental regulations, will the supply curve for a film account for private costs, external costs, both, or neither? Explain.
Refer to Table 12.2. The externality created by the refrigerator production was 100. However, once we accounted for both the private and additional external costs, the market price increased by only 50. If the external costs were 100 why did the price only increase by 50 when we accounted for all costs?
What is a pollution charge and what incentive does it provide for a firm to take external costs into account?
Suppose that Sonys R. Is this a private or social benefit?
Consider the case of global environmental problems that spill across international borders as a prisoners dilemma of the sort studied in Monopolistic Competition and Oligopoly. Say that there are two countries, A and B. Each country can cheese whether to protect the environment, at a cost of 10, or not to protect it, at a cost of zero. If one country decides to protect the environment, there is a benefit of 16, but the benefit is divided equally between the two countries. If both countries decide to protect the environment, there is a benefit of 32, which is divided equally between the two centuries. In Table 12.10, fill in the costs, benefits, and total payoffs to the countries of the following decisions. Explain why, without some international agreement, they are likely to end up with neither country acting to protect the environment.
In the Land of Purity, there is only one form of pollution, called gunk. Table 12.14 shows possible combinations of economic output and reduction of gunk, depending on what kinds of environmental regulations you choose. Sketch a graph of a production possibility frontier with environmental quality on the horizontal axis, measured by the percentage reduction of gunk, and with the quantity of economic output on the vertical axis. Which choices display productive efficiency? How can you tell? Which choices show allocative efficiency? How can you tell? In the choice between K and L, can you say which one is better and why? In the choice between K. and N, can you say which one is better, and why? If you had to guess, which choice would you think is move likely to represent a command-and-control environmental policy and which choice is more likely to represent a market-oriented environmental policy, choice L or M? Why?
What is an externality?
(External Costs with Variable Technology) Think of an industry that pollutes the water and has access to variable technology for reducing that pollution. Graphically illustrate and explain the impact of each of the following, other things constant, on the optimal level of water quality: a. New evidence is discovered about a greater risk of cancer from water pollution. b. The cost of pollution-control equipment increases. c. A technological improvement reduces the cost of pollution control.
