Textbook Question
Chapter 12, Problem 44P
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?

A country called Sherwood is very heavily covered with a forest of 50,000 trees. There are proposals to clear some of Sherwood’s forest and grow corn, but obtaining this additional economic output will have an environmental cost from reducing the number of trees. Table shows possible combinations of economic output and environmental protection. a. Sketch a graph of a production possibility frontier with environmental quality on the horizontal axis, measured by the number of trees, and the quantity of economic output, measured in corn, on the vertical axis. b.

2. Efficiency in the presence of externalities
Air horns impose many external costs on society: the risk of being deafened, the annoyance of being awakened in the middle of the night, and so on.
Therefore, the market equilibrium quantity of air horns is not equal to the socially optimal quantity. The following graph shows the demand for air
horns (their private value), the supply of air horns (the private cost of producing them), and the social cost of air horns, including both the private cost
and external costs.
Use the black point (plus symbol) to indicate the market equilibrium quantity. Next, use the purple point (diamond symbol) to indicate the socially
optimal quantity.

9. Efficiency in the presence of externalities
Wildflowers grant many external benefits on society: the benefits they bestow on pollinators and other native species, improving local ecosystems,
and so on. Therefore, the market equilibrium quantity of wildflowers does not equal the socially optimal quantity. The following graph plots the
demand for wildflowers (their private value), the supply of wildflowers (the private cost of producing them), and the social value of wildflowers,
including both the private value and external benefits.
Use the black point (plus symbol) to indicate the market equilibrium quantity. Next, use the purple point (diamond symbol) to indicate the socialy
optimal quantity.

- It’s common to think that reducing pollution is necessarily costly because to reduce pollution we need to tax firms who will then produce less. But can you think of one example in which pollution might not only be unpleasant but might actually reduce production?arrow_forwardPRICE OF CARS 1. Efficiency in the presence of externalities Cars impose many external costs on society: carbon dioxide emissions that contribute to air pollution, congestion on roadways, and so on. Therefore, the market equilibrium quantity of cars is not equal to the socially efficient quantity.

- Explain why zero pollution should not be the goal for a society.arrow_forwardChapter 8 in Tietenberg and Lewis looks at climate change, the most important environmental issue of our time. Economists generally agree that putting a price on carbon is the best approach to reducing climate warming carbon emissions. The two main strategies for doing this are carbon taxes and the cap and trade version of emissions trading. Discuss the pros and cons to these two approaches to pricing carbon. Why do economists favor these kinds of market-based strategies to pollution control over “command and control” approaches such technology standards?arrow_forward3:31 100- 90 80 70 60 50 40 30 20 10 price 30 10 20 30 40 50 60 70 80 90 100 thousands of trees as many as possible MPC=MSC Trees planted in urban areas improve air quality, reduce soil erosion, and moderate temperature in hot cities.

For example, for Firm A to eliminate one unit of pollution, it would cost $54, and for Firm A to eliminate a second unit of pollution it would cost an additional $67. Refer to Table 3. If the government charged a fee of $90 per unit of pollution, how many units of pollution would the arms eliminate altogether? Guess: 11 Question 2: Refer to Figure 5 (Graph 4).

In 2019, there will be 20 tons of emissions produced. The governor’s office has run the calculations and found that the socially optimal level is 14 tons and the marginal damage from each unit of pollution is $150. Imagine there are two types of drivers in California: commuters and non-commuters. Imagine that the marginal cost of reducing pollution for commuters is MCA_C=150Q and the marginal cost of reducing pollution for non-commuters is MCA_N=30Q. Each type initially created ten tons of pollution each. Their total cost of reductions is equal to TCA_C=75Q^2 and TCA_N=15Q^2. How much would each type choose to reduce under the tax? Imagine the governor instead suggested forcing all drivers to reduce their emissions by 30% from their 2019 levels. How would the costs of reduction here compare to the taxation case (please provide actual numbers)? Do you…arrow_forward
- 8.1 Suppose we have an agricultural valley 100 km by 50 km, with a polluting electricity power plant. The power plant causes pollution problems in a narrow strip of land downwind of the plant, and within this valley. 10 km in length and 500 m in width, but no problems outside of that area. The total effect of the pollution is to make crop land less productive. If we were to clean up the pollution, would we expect land prices to increase? Where? Would we expect wages to decline? Would the changes in land prices and/or wages fully reflect the benefits of cleaning up the pollution? Why or why not?arrow_forwardA chemical factory emits waste products into a river. The waste products affect a fishery downstream. Suppose MD- 2E and MAC-60-3E.

What will be the emission level in the cquilibrium? What is the price per unit? Who should pay how much to whom? What are the total gains from trade for the chemical factory? What are the total gains from trade for the fishery? What are the total damages? What are the total abatement costs? c) Suppose the fishery has the property rights to use the river, and the two parties trade on property rights with a single price for all units.

Complete the following table with the action each firm will take at this permit price, the amount of pollution each firm will eliminate, and the amount it costs each firm to reduce pollution to the necessary level. If a firm is willing to buy two permits, assume that it buys one permit from each of the other firms. (Hint: Do not include the prices paid for permits in the cost of reducing pollution.)
