Figure 5-9 Figure 5-9   Companies producing toilet paper bleach the paper to make it white. The bleach is discharged into rivers and lakes and causes substantial environmental damage. Figure 5-9 illustrates the situation in the toilet paper market. -Refer to Figure 5-9. An efficient way to get the firm to produce the socially optimal output level is A)  for government to set a quota on the quantity of toilet paper that the toilet paper industry can produce. B)  to impose a tax to make the industry bear the external costs it creates. C)  to grant a subsidy to enable the industry to internalize the external costs of production.

Figure 5-9 illustrates the situation in the toilet paper market. -Refer to Figure 5-9. Let's suppose the government imposes a tax of $50 per unit of toilet paper to bring about the efficient level of production. What happens to the market price of toilet paper? A)  It rises by $50 per unit. B)  It rises by more than $50 per unit. C)  It rises by less than $50 per unit. D)  It remains the same because the tax is imposed on producers who create the externality. Companies producing toilet paper bleach the paper to make it white.

B) would be less than the amount at which the marginal benefit of pollution reduction equaled the marginal cost.
C) would be the same as if it would be if the owners of the smelter were legally liable.

Figure 5-11 Figure 5-11   Coal burning utilities release sulfur dioxide and nitric acid which react with water to produce acid rain. Acid rain damages trees and crops and kills fish. Because the utilities do not bear the cost of the acid rain, they overproduce the quantity of electricity. This is illustrated in Figure 5-11. -Refer to Figure 5-11. S<sub>1</sub> represents the supply curve that reflects the marginal private cost of production and S<sub>2</sub> represents the supply curve that reflects the marginal social cost of production. One way to internalize the external cost generated by utilities is to impose a Pigovian tax on the production of electricity.
