People could organize a race, and solicit donations to support the race. People can also run some other charity, like for a cancer, and solicit donations to support that charity. The question is why these two charities are so often combined. Many people would not give money to someone soliciting for a race by itself, or for someone soliciting for a cancer charity by itself, but they do give money to someone soliciting for a cancer run. Why the extra willingness to donate to this combined solicitation? Robin Hanson [EMAIL PROTECTED] http://hanson.gmu.edu Asst.
