A country called Sherwood is very heavily covered with a forest of 50,000 trees. There are proposals to clear some of Sherwoods forest and grow com, but obtaining this additional economic output will have an environmental cost from reducing the number of trees. Table 12.11 shows possible combinations of economic output and environmental protection. 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. Which choices display productive efficiency? How can you tell? Which choices show allocative efficiency? How can you tell? In the choice between T and R, decide which one is better. Why? In the choice between T and S, can you say which one is better, and why? If you had to guess, which choice would you think is more likely to represent a command-and-control environmental policy and which choice is more likely to represent a market-oriented environmental policy, choice Q or S? Why?

Figure 5-4Suppose there are several paper mills producing paper for a market. These mills, located upstream from a fishing village, discharge a large amount of wastewater into the river. The waste material affects the number of fish in the river and the use of the river for recreation and as a public water supply source. Figure 5-4 shows the paper market. Use this Figure to answer the following question(s).Refer to Figure 5-4. What does S1 represent? Question 4 options: A) the market supply curve that reflects social cost B) the market supply curve that reflects only external cost C) the market supply curve that reflects only private benefit D) the market supply curve that reflects private cost
Consider two ways of protecting elephants from poachers in African countries. In one approach, the government sets up enormous national parks that have sufficient habitat for elephants to thrive and forbids all local people to enter the parks or to injure either the elephants or their habitat in any way. In a second approach, the government sets up national parks and designates 10 villages around the edges of the park as official tourist centers that become places where tourists can stay and bases for guided tours inside the national park. Consider the different incentives of local villagers-who often are very poor-in each of these plans. Which plan seems more likely to help the elephant population?

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?
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.
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?

Within the dorm room, is the showing of a moviea public good? Why or why not?b. If it costs $8 to stream a movie, how many moviesshould the roommates stream to maximize totalsurplus?c. If they choose the optimal number from part (b)and then split the cost of streaming the moviesequally, how much surplus does each personobtain from watching the movies?d. Is there any way to split the cost to ensure thateveryone benefits? What practical problems doesthis solution raise?e. Suppose they agree in advance to choose theefficient number and to split the cost of the moviesequally. When Dwayne is asked his willingness topay, will he have an incentive to tell the truth?

Quèstion 10 2'sweswwwewewE 2 Answer OXAGON is an industrial city that will be built in NEOM. One of the factories interested to join there has been producing a dependable product used by farmers, municipalities, and suburbanites alike to co mdl grass in fields and gardens. Contributions to NEOM revenue have been minimized by international dumping of generic glyphosate, as announced in mid-2021 due to Pandemic of COVID-19. The factory sales price was decreased from $4,072 to $60,308 per gallon to compete with the highly competitive pricing, and it is expected that the international price will be around $6,968 per gallon. Assume when the price was set at $4,072 per gallon, there was a prediction that in 5 years the price would inflate to $9,853 per gallon. Determine the interest adjusted rate for inflation, if the inflation is 11% and the interest is 3% per year real return is expected by the factory.
