Consider a second hand car market where three types of cars are being sold: High quality (H), medium quality (M) and low quality (L). Sellers value an H at $2000, an M at $1200 and an L at $800, whereas buyers value an H at $1800, an M at $1600 and an L at $1400. As discussed in the "Akerloff's Lemons Market", sellers are able to distinguish between different quality cars but buyers are not and a buyer believes that in this market 40% of the cars is an H, 30% of the cars is an M and 30% of the cars is an L. a) Determine which type of cars will be sold at the efficient allocation. b) Determine which type of cars will be sold at the market equilibrium.

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.)
