There are three industrial firms in a town Firm Initial Pollution Level Cost of Reducing Pollution by 1 Unit A 30 units $20 40 units 20 units B с $30 $10 The government wants to reduce pollution to 60 units, so it gives each firm 20 tradable pollution permits. 1. Who sells permits and how many do they sell? Who buys permits and how many do they buy? Briefly explain why the sellers and buyers are each willing to do so. What is the total cost of pollution reduction in this situation? 2. How much higher would the costs of pollution reduction be if the permits could not be traded?
The table below shows the demand for pollution permits to emit hydrocarbons in a particular industrial park. Each permit allows the owner to release one tonne of pollutants into the atmosphere.

If no fee for a pollution permit were charged, how many tonnes of pollutants would be discharged into the atmosphere, assuming a straight-line demand curve? Quantity: tonnesb. Suppose government were to set a fee of $3,500 per pollution permit. How many tonnes of pollutants would now be dumped? What is the total revenue received by government? Quantity: tonnes Total revenue: $ c. Suppose that a new technology allows for a significant reduction in hydrocarbons at a relatively low cost so that the demand for pollution permits in the industrial park drops by 150 tonnes. Assuming that government holds the permit fee at $3,500, how many tonnes of…

The following table shows the marginal 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 $54, and for Firm A to eliminate a second unit of pollution it would cost an additional $67. Firm Unit to be eliminated A B C D First unit 54 57 54 62 Second unit 67 68 66 73 Third unit 82 86 82 91 Fourth unit 107 108 107 111 Refer to Table 5.

cap-and-trade and windfall profitsA city called Seoul is suffering from high concentrations of mercury in the air, caused by burningcoal in power plants. There are two of these plants close to the city. The city’s mayor wants touse cap-and-trade to reduce emissions to a reportedly “safe” level of 60 tons. The two firms havethe following marginal benefits of emissions: MB1 = 100 – 2e1, MB2 = 25 – 0.5e2.a. How much mercury will each firm emit? What allowance price will prevail in themarket?Firm 2 hires a smart lobbyist who convinces the government that its profits are relatively low andthat it therefore deserves a generous allowance allocation. The government agrees and allocatesa1 = 20 allowances to firm 1 (for free) and a2 = 40 allowances to firm 2 (for free).b. What are the firms’ profits? Do any of the firms earn windfall profits? [Hint: compareprofits with and without regulation.] Windfall profits have been sharply criticized by consumer advocacy groups and politicians.c. What can…
wo firms, A and B, each currently dump 50 tonnes of chemicals into the local river. The government has decided to reduce the pollution and from now on will require a pollution permit for each tonne of pollution dumped into the river. It costs Firm A $100 for each tonne of pollution that it eliminates before it reaches the river, and it costs Firm B $50 for each tonne of pollution that it eliminates before it reaches the river. The government gives each firm 20 pollution permits. Government officials are not sure whether to allow the firms to buy or sell the pollution permits to each other. What is the total cost of reducing pollution if the firms are NOT allowed to buy and sell pollution permits from each other, and what is the total cost of reducing pollution if the firms ARE allowed to buy and sell permits from each other? A. $4500; $2500 B. $3000; $1500 C. $4500; $3500 D. $4500; $4000
The figure below shows the marginal benefit (demand) of polluting for two firms: Alpha and Beta. Before the introduction of a pollution tax, pollution is free, that is, MC = $0 per ton of emissions. Marginal Benefit (MB) to Firm Tax = $100 0 MB BETA MBALPHA 25 50 75 100 Emissions (tons) The government decides to impose a tax on pollution of $100 per ton of emissions. That is, the per-unit the tax is the marginal cost of polluting. Which of the follow are true? (Select all that are true.) a. As a result of the tax, the total emissions will decrease by 50 units b. The tax was intended to decrease production by 50 units for each firm. c. As a result of the tax, both firms will decrease emissions by the same amount d. After the tax is imposed, Firm Beta will emit 50 tons more pollution than Firm Alpha e. Before the tax is imposed, Firm Beta emitted more pollution than Firm Alpha f. As a result of the tax, total emissions from the two firms will be cut in half g. The amount of tax collected…
