(a) What would be the economically efficient number of wells? (Solve to the nearest multiple 10 wells.) Explain why social benefits (profits) are maximized at this level of output. [Hint: Calculate the total revenue and marginal revenue for each number of wells.] (b) If each well is privately owned by a different farmer without any regulations, how many wells will operate? (Solve to the nearest multiple 10 wells, or for example, you could say between 10 and 20 wells.) Is this number of wells economically efficiency? Also, is this number of wells ecologically sustainable in the long-term? [Hint: Calculate the average revenue for each number of wells.]e (c) Suppose a new technology is adapted that reduces the cost of operating a well from 600 to 400 pesos. Now what is socially efficient (i.e. profit maximizing) number of wells with the new technology? How has the introduction of this new technology affected environmental sustainability?

1. Suppose that a polluting activity has marginal damage and marginal abatement costs given by MD=2E and MAC = 210 - 3E, respectively. Suppose that the polluter(s) are held liable for damages. (a) What level of emissions will be chosen by polluters. (b) Compute the amount of damages (compensation) that will be paid by polluters and the total of all costs paid by polluters. (c) Compute the social gains from instituting legal liability, relative to the no-abatement outcome.

1. Suppose Brazos County is considering preserving certain miles of Navasota River, but they have no clue how many miles of the river they should preserve. The county officials are seeking advice from a bright environmental economist. They contacted you for help. Suppose marginal benefit for preserving the river is given by P = 10 - ½ q and marginal costs are 2 + ½ q. You are asked to answer the following questions for the country office. Show the work. a) What is the net benefit of preserving six miles of the river? b) What is the benefit/cost ratio of preserving six miles of the river? c) How many miles of Navasota River should the Brazos County preserve? Why?
