. He also interviewed some other people, including Ruthann Leishman who now manages one of the active kidney exchanges, at UNOS, but who I met when she helped launch the New England Program for Kidney Exchange. You'll also hear from an incompatible patient-donor pair who quickly found a match, and the nondirected donor who started the chain that worked for them.. We end the conversation over dinner...

Our latest Freakonomics Radio episode is called “Make Me a Match.” (You can subscribe to the podcast at iTunes or elsewhere, get the RSS feed, or listen via the media player above. You can also read the transcript, which includes credits for the music you’ll hear in the episode.)
The gist of the episode: Sure, markets generally work well. But for some transactions — like school admissions and organ transplants — money alone can’t solve the problem. That’s when you need a market-design wizard like Al Roth.
ROTH: I was, you know, a poor ungrateful student who didn’t appreciate what my teachers were trying to do for me. You should tell all your listeners they should complete high school.
Roth has also just published a very fine new book that is a great survey of his work — and his worldview, which is just as impressive. It’s called
Who Gets What—and Why: The New Economics of Matchmaking and Market Design
In the podcast, I visit Stanford to speak with Roth about market design, what’s it’s like to get that middle-of-the-night Nobel phone call, and why the world needs an economist-engineer like him in the first place:
ROTH: Matching markets are markets where money, prices don’t do all the work. And some of the markets I’ve studied, we don’t let prices do any of the work. And I like to think of matching markets as markets where you can’t just choose what you want even if you can afford it — you also have to be chosen. So job markets are like that; getting into college is like that. Those things cost money, but money doesn’t decide who gets into Stanford. Stanford doesn’t raise the tuition until supply equals demand and just enough freshmen want to come to fill the seats. Stanford is expensive but it’s cheap enough that a lot of people would like to come to Stanford, and so Stanford has this whole other set of market institutions. Applications and admissions and you can’t just come to Stanford, you have to be admitted.
You’ll hear how Roth and others have revolutionized the organ-donor market, and we hear the amazing story of how one
particularly selfless woman kicked off a donor chain that gave life to many others. And you’ll also hear
Ruthanne Leishman, from the United Network For Organ Sharing, talk about the organ-donor algorithm developed by Roth and his colleagues:
LEISHMAN: It’s saving a lot of lives. We have about 600 kidney-paired donation transplants a year right now in the United States. In 2000, we had 2. … We would have stayed doing 2 or 4 or 6 a year without the algorithm.
The next time you hear someone say that economists are a bunch of selfish good-for-nothings, feel free to counter by telling them about the fine work of Al Roth.
