The optimal quantity of air pollution is
found by equating the marginal benefits from further reductions in pollution and the
marginal costs of further reductions in pollution.
whatever amount of pollution is produced by the profit maximizing firm.
found by setting the quantity of air pollution equal to the quantity of water pollution.
a meaningless concept since monetary values cannot be attached to problems associated with
pollution.
Suppose there are two firms on a river and the production processes of both require clean water.
The upstream firm’s process dirties the water, which it dumps back into the river. The downstream
firm must clean the water before using it in its production process. If the two firms would merge
the external costs of the upstream firm are private costs after the merger.
the internal costs of the downstream firm become external costs of the merged firm.
the total costs of production fall since the external costs disappear.
the external costs of the merged firm would equal the external costs of the upstream firm,
which would then be passed on to its customers.
The idea that it takes 90 percent of your time to clean up the last 10 percent of your house illustrates
that
the marginal cost of cleaning up slopes upward.
the marginal cost of cleaning up slopes downward.
the marginal benefit of cleaning up is constant.
the marginal benefit of cleaning up slopes upward.
If pollutants from smoke stacks in a city such as Newark causes people to paint their homes and
cars more frequently, this implies
internal cost to home and car owners.
external benefits to the home and car owners.
external costs on home and car owners.
