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. Your roommate is a smoker, but you are a nonsmoker.
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?
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?
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?
What is a pollution charge and what incentive does it provide for a firm to take external costs into account?
