Two firms are ordered by the Government to reduce their pollution levels. Firm A’s marginal costs associated with pollution reduction are MC = 20 + 4Q. Firm B’s marginal costs associated with pollution reduction are MC = 10 + 8Q. The marginal benefit of pollution reduction is MB = 400 – 4Q. Compare the social efficiency of the three possible outcomes: (1) require both firms to reduce pollution by the same amount; (2) charge a common tax per unit of pollution; (3) require both firms to reduce pollution by the same amount but allow pollution permits to be bought and sold.

The following table shows the current level of toxic waste dumped by two firms and the marginal cost of cleaning up additional 10 lbs increments of waste. Suppose the government has imposed a pollution tax of $7 per 10 lbs of waste. Calculate the reduction in total pollution and the total cost to the firms of doing so?

Two identical firms save money from polluting. A firm’s marginal savings from emitting an amount e are given by 10 − 2e. The two firms differ in their impact on ambient pollution concentrations. Two units of emissions from firm 1 result in one unit of ambient pollution, while one unit of emissions from firm 2 results in one unit of ambient pollution. a) Initially the policy-maker decides to institute a standard cap and trade program instead of regulating ambient pollution. If each firm is initially given three emission permits, how many permits will each firm end up with and what will be the price? b) The policy-maker realizes the differences between the firms and de- cides to institute ambient pollution permit trading. What are the transfer coefficients for each of the firms? If instead each firm is given two ambient pollution permits and trading takes place, how much will each firm end up emitting, and what will be the price?
Suppose the United States has two utilities, Commonweath Utilities and Consolidated Electric. Both produce 20 million tons of sulfur dioxide pollution per year. However, the marginal cost of reducing a ton of pollution for Commonwealth Utilities is $200 per ton and the marginal cost of reducing a ton of pollution for Consolidated Electric is $225 per ton. The government's goal is to cut sulfur dioxide pollution in half (by 20 million tons per year). If the government issues 10 million tradable pollution permits to each utility, what will be the cost of eliminating half of the pollution to society? million per year. Using a cap-and-trade system of tradable emission allowances will eliminate half of the sulfur dioxide pollution at a cost of $
The following table shows the marginal costs for each of the four firms (A, B, C, and D) to eliminate units of pollution from their production processes. For example, for Firm A to eliminate one unit of pollution, it would cost $ 54, and for Firm A to eliminate a second unit of pollution it would cost an additional$67. Refer to Table 10-5. Suppose the government wants to reduce pollution from 16 units to 8 units and auctions off 8 pollution permits to achieve this goal. Which of the following is a likely auction price for the permits? a.$69b.$97c.$81d. 583
Problem 5 refers to the following setup: The demand curve in a market is Q = 6-P. Firm A and B are the only sellers, their marginal costs are constant at 2 and 3 respectively, and there is no fixed cost. They produce identical goods. 5. a) What is the socially efficient outcome? (Specify the quantity for each firm.) b) Find the quantity produced by each firm and the price under Cournot competition. c) What is each firm's profit under Cournot competition?
The following table shows the total costs for each of four firms (A,B,C, and D) to eliminate units of pollution from their production processes. For example, for Firm A to eliminate one unit of pollution, it would cost $40, and for Firm A to eliminate two units it would cost a total of $105. If the government charged a tax of $74 per unit of pollution, how many units of pollution would the firms eliminate altogether?

Two firms are ordered by the federal government to reduce their pollution levels. Firm A’s marginal costs associated with pollution reduction are MC = 150 + 3Q. Firm B’s marginal costs associated with pollution reduction is MC = 9Q. The marginal benefit of pollution reduction is MB = 250-4Q. A.What is the socially optimal level of each firm’s pollution reduction? B. Compare the social efficiency of three possible outcomes: Require all firms to reduce pollution by the same amount (half of the total calculated in part a); Charge a common tax per unit of pollution; Require all firms to reduce pollution by the same amount, but allow pollution permits to be bought and sold
Suppose a municipality votes to reduce the combined pollution introduced by three local companies. Presently, each firm cre the area, for a total of 12 pollution units. The government can reduce total pollution in the area to 6 units by choosing between the following two methods: Methods to Reduce Pollution 1. The government imposes pollution standards using regulation. 2. The government issues tradable pollution permits. The costs faced by each firm are different, so it is more difficult for some firms to reduce pollution than others. The following table shows the cost faced by each firm to eliminate each unit of pollution. Assume that the cost of eliminating all 4 units of pollution (that is, reducing pollution to zero) is prohibitively expensive for all three firms.

Power stations emit sulfur dioxide as a waste product. This generates a cost to society that is not paid for by the firm; therefore, pollution is a negative externality of power production. Suppose the U.S. government wants to correct this market failure by getting firms to internalize the cost of pollution. To do this, the government can charge firms for pollution rights (the right to emit a given quantity of sulfur dioxide). The following graph shows the daily demand for pollution rights. 1) Suppose the government has determined that the socially optimal quantity of sulfur dioxide emissions is 350 million tons per day. One way governments can charge firms for pollution rights is by imposing a per-unit tax on emissions. A tax (or price in this case) of $............per ton of sulfur dioxide emitted will achieve the desired level of pollution. 2) Now suppose the U.S. government does not know the demand curve for pollution and, therefore, cannot determine the optimal tax to…
The primary source of air pollution in the small town of Smokey, Nevada is a nearby steel mill. The local environmental agency has decided that the mill needs to reduce its emissions because the town's population is located directly downwind from it. Currently the agency is considering three different approaches to reducing pollution from the mill: a technology standard, an emission standard and an emission tax. Why might the owner of the mill prefer an emission standard to a technology standard that would produce the same level of emissions? a Because with emission standards the polluter is more flexible in selecting the technology that will minimize her abatement cost Ob. Because polluters usually try to stick to their existing technology O C. Because it has been proven to be easier to implement O d. Because polluters, as all producers are suspicious about new technologies
