Economics Saves Lives — sometimes in overt fashion, like this donor-pairing program by economist Alvin Roth:
Becky Borchert, a Wisconsin nurse, was eager to donate a kidney to her gravely ill friend in New York, but she had type A blood and her friend had type B. Richard Krafton, a school administrator in Massachusetts with advanced kidney disease, had the opposite problem: The friend who wanted to give him a kidney had type B blood, not a match for Krafton’s type A.But last week, Borchert saved her friend’s life by giving a kidney to Krafton, a man she did not know, in the first test of a system that brings together strangers to exchange organs for transplant. At the same moment that surgeons at Massachusetts General Hospital began removing Borchert’s kidney for Krafton, another surgical team at New York Presbyterian Hospital started taking a kidney from Krafton’s friend, Steve Proulx, to implant in Borchert’s friend, who asked to remain anonymous.
