Suppose that Sonys R. Is this a private or social benefit?
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.
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 marketable permit and what incentive does it provide for a firm to account for external costs?
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?
Identify the following situations as an example of a negative or a positive externality: You are a birder (bird watcher), and your neighbor has put up several birdhouses in the yard as well as planting trees and flowers that attract birds. Your neighbor paints his house a hideous color. Investments in private education raise your countrys standard of living. Trash dumped upstream flows downstream right past your home.

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?
Name two public goods and explain why they are public goods.
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.
Consider two approaches to reducing emissions of CO2 into the environment from manufacturing industries in the United States. In the first approach, the U.S. government makes it a policy to use only predetermined technologies. In the second approach, the U.S. government determines which technologies are cleaner and subsidizes their use. Of the two approaches, which is the command-and-control policy?
