If the power plant had to pay a price that re ected the harm it causes to others both to individuals and to other rms by converting clean air and water into dirty air and water, then the allocation of power, air, and water would be socially optimal.

Just as in the case of smoking in a restaurant, establishing a property right to either clean air and water or a property right giving the power plant the right to pollute the air and water would in principle work to produce a socially optimal allocation of both power and the degree of pollution of air and water. It is worth pointing out that social optimality is unlikely to mean there would be no pollution. Instead, it simply requires that the amount of pollution, like the amount of all other goods, is determined so that there is no reallocation that improves welfare.

But also, just as in the case of the restaurant, the transaction costs involved in negotiation between the power plant and all those affected by its activities may be prohibitive. Mechanisms for Determining Socially Optimal Allocations. One dif culty with using property rights and mutually agreeable compensation to determine the socially optimal allocation in our power plant example is the following: how do we discover the true amount of harm created by the pollution If we simply ask people how much harm they suffer from pollution, and attempt to use this information to decide whether or not to allow the pollution, then each person who is harmed has an incentive to overstate the amount of harm.

Similarly, the rm creating the pollution has an incentive to overstate the cost of reducing its pollution. However, there is a procedure that can be used to address this incentive problem and we have already analyzed a special case of it. In 15, we demonstrated that the Vickrey Clark Groves (VCG) mechanism results in an ef cient matching of sellers to buyers in a matching market (in the speci c context of advertising slots and advertisers), even when the buyers valuations for items are not known.

This occurs because VCG pricing makes truth-telling a dominant strategy for buyers. A similar mechanism can be used to induce truth-telling for polluters and for those who suffer the harm created by pollution. The pollution setting is a bit more complex because the valuations of both the buyers (polluters) and the sellers (affected individuals) are unknown.

Here we might imagine the government running the mechanism, collecting revenue from the polluter and providing compensation to individuals harmed by the pollution. The goal of this mechanism is to determine the socially optimal amount of pollution; it is not to use the money collected from the polluter to fully compensate those who are harmed by the pollution. In fact, individuals may be better or worse off once the mechanism is run and the payments occur.

In addition, the amount of revenue collected may not equal the amount of compensation, so the government may run either a surplus or a de cit.2 Actually running the VCG mechanism to determine the optimal amount of pollution would be dif cult and costly. The rst problem is to determine who is potentially harmed by the pollution and thus who should be included in the mechanism.

Next, the mechanism would have to be rerun every time the group of affected individuals changes.
