Question: In October 2001, Barry Bonds of the San Francisco Giants hit his record-setting 700th home run. After fan Alex Popov caught the ball, another fan, Patrick Hayashi, bumped him and grabbed the ball when he dropped it. The ball ultimately sold for $450,000 and Popov and Hayashi went to court, where they were ordered to split the money. If you were interested in efficiency, how would you decide the case? Why, if at all, would your exact decision matter?
