B) the tax is less than the external cost associated with the product.

C) the company should advertise the product more.

D) the company should increase the production of the product.

.

32) The marginal cost to society of reducing pollution increases with the increased use of

pollution abatement because

A) of the diminishing marginal utility of abatement.

B) of the reduced demand for abatement.

C) of the diminishing returns from abatement.

D) of the high cost of abatement.

33) All of the following are choices for the polluter when faced with additional costs to abate the

externality EXCEPT

A) ignore the government regulations.

B) install pollution abatement equipment.

C) reduce the pollution-causing activity.

D) pay the price to pollute.

34) The government is considering levying a tax on the pollution generated from two electric

power plants (Plant A and Plant B). Plant A is located in a city with a high density of

population, and Plant B is located in the rural area with a low density of population. The

government should

A) levy the same tax per unit of pollution on both plants.

B) levy a higher tax per unit of pollution on Plant A because of its higher economic damage.

C) levy a higher tax per unit of pollution on Plant B because of its lower economic damage.

D) tax only Plant A but not Plant B because Plant B generates less revenue.

35) To correct for the social impact of pollution, the government should levy a per-unit tax

A) that is the same for all polluters regardless of their locations or sizes.

B) according to the economic damage of the pollution.

C) according to the business activity of the polluter.

D) only to those polluters that can afford to pay for the tax.

36) Suppose that the nation wide average cost of air pollution generated by a car is $1,000.

Would a tax of $1,000 on every car induce people to take external costs into consideration and

bring about the optimal price and output for autos? Explain.

37) Using a graph, show the effects of a negative externality. Where is the socially optimum

point of output? How can it be achieved?

Answer: No. The concept of externality is about the economic costs rather than the amount of

externality. The economic costs or damages can vary across different locations so that the

optimal tax on pollution should also vary from location to location, depending on the size of

economic damages.
