Answer to Question 1

A cap-and-trade scheme is a market-based approach to setting the quantity of pollution to the socially optimal level. Polluting firms are given a number of permits for pollution, usually based on their historical levels of pollution. Firms that find it relatively cheaper to reduce pollution would do so and sell their extra permits to firms that find it expensive to reduce pollution. Becausethe number of permits is fixed, total emissions cannot exceed a certain level. Under cap-and-trade schemes, the marginal cost of pollution abatement is equalized across firms.

Answer to Question 2

The statement is false. If the provision of public goods was left to private firms, the public goods would generally not be produced. If these goods have any value to households, this outcome would not be efficient at all. On the other hand, if the government is able to tax households and then provide the goods, a more efficient situation may result.
