We are concerned with the water quality in the Mississippi River. There are 4 groups of people who use the river: environmentalists, fishermen, sightseers, and wastewater plant executives. The marginal benefit function for an improvement in water quality for each of the groups is:
MBe = 15 - Q , MBf = 10 - Q , MBs = 8 - Q , MBw = 6 - 2Q
while the marginal cost of improving water quality is : MC = 1 + Q
a) Derive the aggregate marginal benefit function, Σ MB.
b) What is the efficient level of water quality?
c) Suppose the government performs a study and finds out that the methods used to increase the water quality have an external cost on the environment since the waste removed from the river isn't removed properly and seeps back into the groundwater of a nearby city. they estimate that the social marginal cost function for water quality is MCs = 5+3Q/
1. What is the socially optimal level of water quality?
2. Given a budget equation and set of indifference curves, explain in no more than two sentences how one would determine the optimal bundle.

Corresponding formulas for marginal benefit-marginal cost
: Suppose you can hire your mechanic for up to six hours. The total benefit and total cost functions are B(H)=420H-40H^2 and C(H)=100H+120H^2. The corresponding formulas for marginal benefit and marginal cost are MB(H)=420-80H and MC(H)=100+240H. What ..

What is your marginal benefit of advertising dollars
: Suppose that in addition to repairing your car, you can also spend money advertising. If you repair your car for hours and spend A dollars advertising, your benefit (the amount you revive when you sell your car) is B(H,A)=220H-H^2+2A. Both H and A ar..
