Markets and Partial Controls
Utilitarianism can answer some of the difficulties with Blackstone’s theory. Utilitarians see
environmental problems as market defects, arguing that pollution should be avoided
because it harms society’s welfare.
To make this position clear, it is helpful to distinguish between private costs and social
costs. Private costs are the actual private costs that a firm incurs to produce a commodity.
Social costs include the private costs plus the external costs that the firm does not pay–
the costs of pollution and medical care that result from the manufacture of the commodities.
The divergence of private and social costs is problematic because the divergence means
that price no longer accurately reflects all of the costs of a commodity. This means that
resources are not being allocated efficiently, and society’s welfare consequently declines.
When markets do not take all costs into account, more of a commodity will be produced
than society would demand if it could measure what it is actually paying for the commodity.
In addition, producers ignore these costs and do not try to minimize them. Since goods are
no longer efficiently distributed to consumers, pollution violates the utilitarian principles that
underlie the market system. Third, when the production of a commodity imposes external
costs on third parties, goods are no longer efficiently distributed to consumer. External
costs introduce effective price differentials into the markets and everyone does not pay
equal prices for the same commodities.
In a well-functioning competitive market the value of what buyers and sellers on average
receive from their market exchanges equals the value of what they contribute.
Pollution violates the kind of justice or fairness that characterizes a free competitive market.
When a market generates pollution, there are external costs that some people have to pay
in addition to what they pay for the goods they receive. We also recognize that pollution
violates the rights that characterize a free competitive market.
The remedy for external costs, according to utilitarians, is to internalize external costs to
ensure that the producer pays all of the real costs of production and uses these costs to
determine the price of the commodity. To internalize the costs of pollution, a firm may be
required to pay all those harmed by pollution. A problem with this way of internalizing the
costs of pollution, however, is that when several polluters are involved, it is not always clear
just who is being harmed and by whom. Alternatively, the firm might install pollution control
devices and stop the harm at its source.
This way of dealing with pollution is consistent with the requirements of distributive justice.
Since pollution’s external costs are largely borne by the poor, pollution produces a net flow
of benefits away from the poor and towards the rich. Internalizing these costs can reverse
this flow. However, if a firm makes basic goods, such as food, then internalizing costs may
place a heavier burden on poorer people.
Internalizing external costs is also consistent with retributive and compensatory justice,
because those who are responsible for pollution bear the burden of rectifying it and
compensating those who have been harmed. Taken together, these requirements imply that
(a) the costs of pollution control should be borne by those who cause pollution and who
have benefited from pollution activities, whereas (b) the benefits of pollution control should
flow to those who have had to bear the external costs of pollution. Internalizing external
costs seems to meet these two requirements: (a) The costs of pollution control are borne by
