Allocative efficiency is an economic concept regarding efficiency at the social or societal level. It refers to producing the optimal quantity of some output, the quantity where the marginal benefit to society of one more unit just equals the marginal cost. The rule of profit maximization in a world of perfect competition was for each firm to produce the quantity of output where P = MC, where the price (P) is a measure of how much buyers value the good and the marginal cost (MC) is a measure of what marginal units cost society to produce. A monopolist...

Has no motivation to operate at an output level where P=MC, once a barrier is in place and no longer has to worry about competition.

If Illinois cleans the lake, it will cost them 700 and generate social benefits of 900 - however, Illinois will receive only 600 of those benefits, Wisconsin will receive the remaining 300. If a state does not clean the lake, it experiences a cost of $0. If both states clean the lake, the payoffs will be
