An auto-part manufacturing company is considering the purchase of an industrial robot to do spot welding, which is currently done by skilled labor. The initial cost of the robot is $250,000, and the annual labor savings are projected to be $125,000. Ifpurchased, the robot will be depreciated under MACRS as aseven-year recovery property. This robot will be used for five years after which the firm expects to sell it for $50,000. Thecompany's marginal tax rate is 25% over the project period. Suppose that the project requires a $30,000 investment in working capital at the beginning of the project and the entire amount will be recovered at the end of project life. Determine the net after-tax cash flows for each period over the project life. Assume MARR equals= 15%

4. suppose that pollution in a neighborhood comes from two factories, with marginal benefit curves given by mb1 = 12 – p1 and mb2 = 8 – p2. the level of pollution in the neighborhood is given by p = p1 + p2. the government wants to limit pollution by instituting a pollution-rights market. the government’s desired level of p is 10, so it prints 10 pollution rights and offers them for sale to the firms.a)find the equilibrium selling price of a pollution right, as well as the allocation of rights (and hence pollution levels) across the two factories. b)repeat part (a) for the case where the government’s desired level of pollution equals 14. c)comment on the usefulness of a pollution rights market in achieving efficient levels of pollution abatement.

2. which of the following statements about interest is true? a. interest is a one-time fee that you pay for lending money. b. interest is expressed as a percentage of the amount you are borrowing. c. because interest rates tend to be small numbers, they typically don't have much effect on the price of the goods you're purchasing. d. interest is a penalty that you pay when you don't pay your bills on time.

The new york times (nov. 30, 1993) reported that “the inability of opec to agree last week to cut production has sent the oil market into turmoil . . [leading to] the lowest price for domestic crude oil since june 1990.” why were the members of opec trying to agree to cut production? so they could save more oil for future consumption so they could lower the price so they could raise the price why do you suppose opec was unable to agree on cutting production? because each country has a different production capacity because each country experiences different production costs because each country has an incentive to cheat on any agreement the newspaper also noted opec’s view “that producing nations outside the organization, like norway and britain, should do their share and cut production.” what does the phrase “do their share” suggest about opec’s desired relationship with norway and britain? opec would like norway and britain to keep their production levels high. opec would like norway and britain to act competitively. opec would like norway and britain to join the cartel.
