Textbook Question
Chapter 9, Problem 8P
A city water and waste-water department has a four-year-old sludge pump that was initially purchased for $65,000. This pump can be kept in service for an additional four years, or it can be sold for $35,000 and replaced by a new pump. The purchase price of the replacement pump is $50,000. The projected MVs and operating and maintenance costs over the four-year planning horizon are shown in the table that follows. Assuming the MARR is 10%, (a) determine the economic life of the challenger and (b) determine when the defender should be replaced.

Consider a single firm that manufactures chemicals and generates pollution through its emissions E. Researchers have estimated the MDF and MAC curves for the emissions to be the following: MDF = 4E and MAC = 125 – E Policymakers have decided to implement an emissions tax to control pollution. They are aware that a constant per-unit tax of $100 is an efficient policy. Yet they are also aware that this policy is not politically feasible because of the large tax burden it places on the firm. As a result, policymakers propose a two- part tax: a per unit tax of $75 for the first 15 units of emissions an increase in the per unit tax to $100 for all further units of emissions With an emissions tax, what is the general condition that determines how much pollution the regulated party will emit? What is the efficient level of emissions given the above MDF and MAC curves? What are the firm's total tax payments under the constant $100 per-unit tax? What is the firm's total cost of compliance…arrow_forward

Does the same intuition apply to Nathaniel's decision of when to cut his trees? What condition will hold at the equilibrium level of fishing in an open-access fishery? Use a graph to explain your answer, and show the level of fishing effort. Would this same condition hold if there was only one boat in the fishery? If not, what condition will hold, and why is it different? Use the same graph to show the single boat's level of effort. Suppose you are given authority to solve the open-access problem in the fishery. What is the key problem that you must address with your policy?arrow_forward1.
