Pollution Buster, Inc., in considering a pruchase of 10 additional carbon sequesters for $100,000 a piece. The sequesters lasts for only one year until saturated with carbon. Then the carbon is removed and sold.

a) Suppose the government guarantees the price of carbon. At this price, the payoff after 1 year is guaranteed to be $115,000. How would you determine the opportunity cost of capital for this investment?

b) Suppose instead that the sequested carbon has to soldon the London Carbon Exchange. Carbon prices have been extremely volatile, but Pollution Busters' CFO learns that average rates of return from investment on that exchange have been about 20%. She thinks that is reasonable forceast for the furture. What is the opportunity cost of capital in this case? Is the purchase of an additional sequester a worthwhile capital investment if she expects that the price of extracted carbon will be $115,000?

An employer who is considering hiring eva has asked donna, eva’s former supervisor, for a report on eva. in truth, eva’s work for donna has been only average. however, eva is donna’s friend, and donna knows that eva probably will not get the job if she says anything negative about eva, and donna knows that eva desperately needs the job. further, donna knows that if the situation were reversed, she would not want eva to mention her deficiencies. nevertheless, it has been donna’s policy to reveal the deficiencies of employees when she has been asked for references by employers, and she knows that some of eva’s faults may be bothersome to this particular employer. finally, this employer has leveled with donna in the past when donna has asked for a report on people who have worked for him. should donna reveal deficiencies in eva’s past performance? (remember to use one of the three moral theories acceptable for this test to solve this dilemma. any discussion of any personal opinion, religious perspective, or theory other than the moral theories acceptable for this test will result in a score of "0" for this question.)
