In a market without environmental regulations, will the supply curve for a film account for private costs, external costs, both, or neither? Explain.
Assume that the marginal private costs of a film producing fuel-efficient can; is greater than the marginal social costs. Assume that the marginal private benefits of a firm producing fuel efficient cars are the same as the marginal social benefits. Discuss one wags.r that the government cans ï¬‚y to increase production and sales of fuel efficient cars to the socially desirable amount. Hint: the government is flying to affect production through costs, net benefits.
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.
A city currently emits 15 million gallons (MG) of raw sewage into a lake that is beside the city. Table 12.13 shows the total costs (TC) in thousands of dollars of cleaning up the sewage to different levels, together with the total benefits (TB) of doing so. Benefits include environmental, recreational, health, and industrial benefits. Using the information in Table 12.13 calculate the marginal costs and marginal benefits of reducing sewage emissions for this City. What is the optimal level of sewage for this city? How can you tell?
Show the market for cigarettes in equilibrium, assuming that there are no laws banning smoking in public. Label the equilibrium private market price and quantity as Pm and Qm. Add whatever is needed to the model to show the impact of the negative externality from second-hand smoking. (Hint: In this case it is the consumers, not the sellers, who are creating the negative externality.) Label the social optimal output and price as Fe and Qe. On the graph, shade in the deadweight loss at the market output.
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?
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 you want to put a dollar value on the external costs of carbon emissions from a power plant. What information or data would you obtain to measure the external [not social] cost?
Suppose that Sonys R. Is this a private or social benefit?
What is a pollution charge and what incentive does it provide for a firm to take external costs into account?
Table 12.12, shows the supply and demand conditions for a firm that will play trumpets on the streets when requested. QS1 is the quantity supplied without social costs. QS2 is the quantity supplied with social costs. What is the negative externality in this situation? Identify the equilibrium price and quantity when we account only for private costs, and then when we account for social costs. How does accounting for the externality affect the equilibrium price and quantity?
