Appalachian Coal Mining believes that it can increase labor productivity and, therefore, net revenue by     reducing air pollution in its mines. It estimates that the marginal cost function for reducing pollution by installing additional capital equipment is MC=40P Where P represents a reduction of one unit of pollution in the mines. It also feels that for every unit of pollution reduction the marginal increase in revenue (MR) is MR=1000-10P How much pollution reduction should Appalachian Coal Mining undertake?

Consider an industry with two firms that emit a uniformly mixed air pollutant (e.g., carbon dioxide). The marginal abatement cost functions for Firm 1 and Firm 2 are: MAC1 = 100 - e1 MAC2 = 100 - 4e2 Aggregate emissions for the industry are denoted as E = e1 + e2. 1. In an unregulated environment how many units of emissions does each firm emit?             Firm 1’s unregulated level of emissions ____________             Firm 2’s unregulated level of emissions ____________             Total unregulated level of emissions ______________ Suppose a regulator has a goal of reducing the total level of emissions from the amount from the amount you answered in [1] to 25 units. The regulator would like to achieve the goal of 25 units of total emissions in a cost-effective way. To do so it issues 25 permits, 10 are given to Firm 1 and 15 are given to Firm 2. A firm can only emit a unit of pollution if they have a permit for that unit, otherwise they must abate. After the permits are allocated,…

Example: Question 4a.) Arthur’s demand to reduce electric and magnetic fields (EMFs) is P = 20 – 2 Q, whileRonald’s demand is P = 15 – 3 Q. If the marginal cost of reducing emissions is equal to$15 and is constant, what is the optimal amount of EMF reduction? b.) What Lindahl prices would you charge Arthur and Ronald? What might prevent you fromcollecting these prices?c.) How would your answers change if the marginal cost of reducing emissions was equal to$10 and is constant?d.) What are the consumer surpluses of Arthur and Ronald in c.)?

Firms in a polluting industry can be classified in two groups: newer firms with a cleaner technology that can abate pollution at a lower marginal cost MCLA = (1/2)aL and older firms with dirtier MCHA = aH, where ai is the level of abatement undertaken by firms of type i = L, H. The social marginal benefit of abating pollution from this particular industry is MBA= 120 - A, where A is the aggregate level of abatement in that industry. To design an efficient emissions standard, the government needs to determine which is the efficient abatement allocation (aL, aH). In order to do this, obtain a cost effective abatement allocation (aL, aH)that provides an aggregate abatement level A = aL + aH, and then proceed to determine the efficient level A (Hint: You should obtain that MCA = A=3)

Consider a lake found in the town of Center Barnstead, and then answer the questions that follow. The town has a campground whose visitors use the lake for recreation. The town also has a fish cannery that dumps industrial waste into the lake. This pollutes the lake and makes it a less desirable vacation destination. That is, the fish cannery's waste decreases the campground's economic profit.        Suppose that the fish cannery could use a different production method that involves recycling water. This would reduce the pollution in the lake to levels safe for recreation, and the campground would no longer be affected. If the fish cannery uses the recycling method, then the fish cannery's economic profit is $1,500 per week, and the campground's economic profit is $1,800 per week. If the fish cannery does not use the recycling method, then the fish cannery's economic profit is $2,000 per week, and the campground's economic profit is $1,000 per week. These figures are summarized…

Consider the following table, describing each person's willingness to pay for different levels (units) mosquito control. Mosquito control is a public good for this society. Demand for Mosquito Control Person A Level WTP($) Person B Person C WTP($) WTP($) 10 25 16 15 20 20 14 12 30 15 12 8. 40 10 10 6. 50 5 8 3 The marginal cost of producing one unit of mosquito control is $35 and constant. Assuming there is no Free-Rider issue, the private level of mosquito control supplied would be units. The optimal level of mosquito control however, would be units.

Suppose that a firm's marginal abatement cost function with existing technologies is MAC = 8 - E. If the firm adopts new pollution abatement technologies, then its marginal abatement cost function will become MAC = 4 - 0.5E. With an emissions tax of $2, the benefits of adopting the new technologies equal $_ Please round your final answer to two decimal places if necessary. Answer:

1. A firm's marginal abatement cost function is given by MAC = 200-5E. Suppose that, after adopting new abatement technology, the firms marginal abatement function becomes MAC = 160-4E. Costs are in dollars per tonne and emissions are in tonnes per year. The firm is given 20 tradeable pollution permits (each permit allows it to emit one tonne of pollution) and the current market price per permit is $100. a)Given no change in the permit price how many tonnes of pollution will the firm emit? b)What will be the firms total abatement cost? Will it buy or sell permits and how many? c) What will be the net cost to the firm after trading? What will be the net gain to the firm from adopting the new abatement technology

ADJ Enterprises produces hydrothermocorticoids. The table below shows the costs of producing various quantities of hydrothermocorticoids.   Quantity Total Cost   Average Cost 0 $0 -- 1 $10 $10.00 2 $12 $6.00 3 $15 $5.00 4 $19 $4.75 5 $24 $4.80 6 $30 $5.00 7 $45 $6.43   ADJ sells its hydrothermocorticoids for $5 each (that is the price regardless of the number of hydrothermocorticoids it sells). Use the Profit-Maximizing Rule to explain the quantity that ADJ should produce to maximize its profits. You may use a calculator. You should explain the details of any calculation you perform. You should identify, explain, and apply the concept you use to answer this question. To receive full credit, your explanation must show all steps in any calculations you perform. Your explanation must also incorporate the profit-maximizing rule – state what that rule is and explain how it applies to ADJ’s situation. Note that it is…
