The government allows sulphur dioxide emissions of 4 parts per billion and has a tradable permits program. The 2 firms in the market pollute at a rate of 5 parts per billion and 6 parts per billion respectively. The 2 firms have the following costs to reduce emissions. The least expensive way to reach the government’s mandate is: Reduction of Sulphur Dioxide Cost - Firm 1 Cost - Firm 2 By 1 part per billion $200,000/year $80,000/year By 2 parts per billion $420,000/year $200,000/year By 3 parts per billion $700,000/year $340,000/year By 4 parts per billion $1,200,000/year $650,000/year Group of answer choices $400,000. $200,000. $340,000.

Under emission standards, the amount of compliance cost faced by a polluter is ___________________________? The total abatement costs Zero The sum of the compensation and abatement costs The compensation based on damages caused by the polluter

A firm has a marginal emissions benefit of 100-0.5*E in each of 2 years, where E measures emissions in tons. The marginal cost of emissions to society is 75/ton. The discount rate is 10% and the marginal cost of emissions also grows at 10% per year. The government decides to give the firm permits to emit 50 tons of emissions per year, but allows the firm to "bank" or "borrow" permits across the two years so that this effectively acts as a 100 ton cap on emissions over 2 years. How much will the firm emit in each year? If all firms are identical to the one you analyze here, is the government issuing too many or too few emission permits relative to the efficient level? How do you know?

Two firms, Kegareta Incorporated and Sucio Enterprises, have access to five production processes, each one of which has a different cost and gives off a different amount of pollution. The daily costs of the processes and the corresponding number of tons of smoke emitted are shown in the accompanying table. Kegareta Incorporated Sucio Enterprises A B D E C 4 tons/day 3 tons/day 2 tons/day 1 tons/day 0 tons/day $ 40 120 $ 85 175 $ 135 250 $ 190 345 $ 250 460 If the government requires each firm to cut its emissions by 25 percent, the total cost of this policy to the society is $

Describe the key symmetry between a pollution emissions tax and an emissions trading scheme. Outline some reasons you might wish to choose one approach in favour of the other when dealing with an emissions-reduction problem.

Bower likes to plant trees in his front year. His neighbors also derive pleasure form the trees in his front year. That is, Bower's trees provide a positive externality for the neighborhood. His marginal private benefit and the marginal social benefit (his and that received by his neighbors combined) are represented on the graph below, along with the marginal cost of planting a tree.

d. What is the socially optimal level of emissions for the industry per month? What would be the resulting total abatement cost per month? Total damage per month? Total social cost per month? e. If environmental authorities wished to control pollution in the industry by imposing an emission tax on pollution, what would be the optimal tax rate per ton of emissions? At this rate, how many tons of pollutants would the industry emit per month? What is the total tax bill to be collected per month? What would be the resulting total abatement cost per month?
