Refer to Fig. 7.4 and Example 7.4 - 'The Effect of Effluent Fees on Input Choices'.How should the manager of a steel plant respond to an EPA-imposed effluent fee of $10 per gallon of wastewater dumped in the river?

1) People who live on the edge of small lakes sometimes have break walls constructed on their property by the shore. A break wall is typically a vertical column of wood or concrete that prevents high water levels from covering part of the owner's property, reducing the size of the beach, and/or eroding the yard. However, several communities have restricted property owners from building break walls. What is one reason for that? Hint: Think about potential externalities of building a break wall. (Short answer) 2)When are quantity restrictions not the same as price restrictions (via taxes)? Describe one situation in which the government would be better off imposing quantity restrictions than setting a tax and explain why quantity restrictions are better in that case. (Short answer)

Corrective taxes Tradable permits One way governments can charge firms for pollution rights is by imposing a per-unit tax on emissions. A tax (or price in this case) of S of chemicals emitted will achieve the desired level of pollution. (?) Now suppose the U.S. government does not know the demand curve for pollution and, therefore, cannot determine the optimal tax to achieve the desired level of pollution. Instead, it auctions off tradable pollution permits. Each permit entitles its owner to emit one ton of chemicals per day. To achieve the socially optimal quantity of pollution, the government auctions off 140…
