Here’s a great idea from Al Roth, the 2012 Economics Nobel Prize winner.
Al got his prize for developing his theoretical matching ideas into a computerized kidney exchange - so if you want to donate a kidney to a family member but you aren’t the right match, you can find another pair of people in the same situation from a different city and criss-cross the pairing, so both kidney transplants can go ahead.
"Mr. Roth, however, wants to go further. The larger the database, the more lifesaving exchanges can be found. So why not open U.S. transplants to the world? Imagine that A and A´ are Nigerian while B and B´ are American. Nigeria has virtually no transplant surgery or dialysis available, so in Nigeria patient A’ will die for certain. But if we offered a free transplant to him, and received a kidney for an American patient in return, two lives would be saved.
The plan sounds noble but expensive. Yet remember, Mr. Roth says, “removing an American patient from dialysis saves Medicare a quarter of a million dollars. That’s more than enough to finance two kidney transplants.” So offering a free transplant to the Nigerian patient can save money and lives. It’s hard to think of a better example of gains from trade (or a better PR coup for the U.S. on the world stage). Better matching with computerized markets is saving lives, but more than 100,000 people are still waiting for kidneys in the United States alone."
