Suppose the government has determined that the socially optimal quantity of sulfur dioxide emissions is 175 million tons per day. 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 $ per ton of sulfur dioxide 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 sulfur dioxide per day. To achieve the socially optimal quantity of pollution, the government auctions off 175 million pollution permits. Given this quantity of permits, the price for each permit in the market for pollution rights will be $ .

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?
