PROBLEMS Reasons for Reluctance because of benefit, it is difficult to demand that
people in developing countries should give up
economic opportunities for the sake of the
environment. because of individual freedom, governments are
reluctant to tell consumers what to buy and
producers how to produce.

another party has to bear some cost associated with that
action. Negative externality the cost that the other people have to carry. Positive externality without some form of intervention or market adjustment, the
producers in each cases do not pay that cost.

that have negative externalities and subsidizing goods that
have positive externalities.

3. 4. Tax is just as effective as a regulation in reducing the overall
level of pollution. The higher the tax, the larger the reduction in
Tax reduces pollution more efficiently. It places a price on the
right to pollute, which allocates pollution to those factories that
face the highest cost of reducing it.
Tax is better for the environment. Under the command-andcontrol policy of regulation, the factories have no reason to
reduce emission further. By contrast, tax gives the factories an
incentive to develop cleaner technologies, because it would
reduce the amount of tax the factory has to pay.
Conclusion: Unlike other taxes, e.g. income tax, distort
incentives and move the allocation of resources away from the
social optimum. Tax raises revenue for the government, also
