3. The effect of negative externalities on the optimal quantityof consumption Consider the market for electric cars. Suppose that a electric car manufacturing facility dumps sludge into a nearby river, creating a negative externality for those living downstream from the facility. Producing additional electric cars imposes a constant per-unit external cost of $210. The following graph shows the demand (private value) curve and the supply (private cost) curve for electric cars. Use the purple points (diamond symbol) to plot the social cost curve when the external cost is $210 per unit.

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?
(Negative Externalities) Suppose you wish to reduce a negative externality by imposing a tax on the activity that creates that externality. When the amount of the externality produced per unit of output increases as output increases, the correct tax can be determined by using a demand-supply diagram; show this. Assume that the marginal private cost curve slopes upward. Negative Externalities: The Market for Electricity in the Midwest:
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?
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.
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?
Do market demand curves reflect positive externalities? Why or why not?
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.
What is a pollution charge and what incentive does it provide for a firm to take external costs into account?
Draw a standard supply and demand diagram for televisions, and indicate the equilibrium price and output. a. Assuming that the production of televisions generates external costs, illustrate the effect of the producers being forced to pay a tax equal to the external costs generated, and indicate the equilibrium output. b. If instead of generating external costs, television production generates external benefits, illustrate the effect of the producers being given a subsidy equal to the external benefits generated, and indicate the equilibrium output.
