Thaler is an American economist. He is perhaps best known as a theorist in behavioral finance, and for his collaboration with Daniel Kahneman and others in further defining that field. He currently teaches at the University of Chicago Booth School of Business, and is an associate at the National Bureau of Economic Research, and has organized a series of behavioral finance seminars along with Robert Shiller, another behavioral finance expert at the Yale School of Management. Previously he taught at Cornell University and the MIT Sloan School of Management Thaler has written a number of books intended for a lay reader on the subject of behavioral finance, including "Quasi-rational Economics" and "The Winner's Curse," the latter of which contains many of his Anomalies columns revised and adapted for a popular audience. Most recently Thaler is coauthor, with Cass R. Sunstein, of "Nudge: Improving Decisions About Health, Wealth, and Happiness" (Yale University Press, 2008). ---------------------------------------------------------------------------------- TRANSCRIPT: Question: What is a “nudge”? Richard Thaler: Let me give you an illustration of a nudge. It’s funny, it’s one paragraph in our book, but it’s by far the most famous example from the book. It turns out some genius who, an economist in fact, allegedly at least, an economist who works for the Amsterdam International Airport Schipol, got the brilliant idea to etch the image of a housefly in the urinals in the men’s bathrooms at the airport. This image of a housefly, it looks extremely realistic. You can see a picture of it on our website nudges.org. It’s located just near the drain. It turns out, that men, when they’re taking care of their business, they’re not fully attending to the task at hand, but, I’m sure there’s an evolutionary explanation for this, if you give them a target, they will aim. According to the people who run the airport, spillage has been reduced by 80%. That housefly has become my favorite illustration of a nudge. So, what’s a nudge? A nudge is some small feature of the environment that attracts our attention and alters our behavior. Question: What is the difference between a nudge and a push? Richard Thaler: It comes down to values. When should we nudge and when should we shove, I think, it’s a political judgment. Obviously in some situations we need shoves, we need laws. Fraud is against the law, murder is against the law, drunk-driving is against the law. We don’t need just nudges. On the other hand, sometimes we can combine the two. So for example, in some states if you’ve been convicted of DWI, Driving While Intoxicated, after you serve your sentence and you get your license back, you also have to equip your car with some device that requires you to pass some sobriety test before you turn the car on. I think that’s probably a good rule. So we can push the two but. Where we’re going to go on various public policy issues will be a political decision, where of course, people will differ. Question: How can we identify and allocate risk better? Richard Thaler: I think the people who’ve been the most overconfident in our business in the last decade have been the people that called themselves risk managers. And the reason is they failed to learned the primary lesson we should have learned from when Long Term Capital Management went belly up ten years ago. That is, investments that seem uncorrelated can be correlated simply because we’re interested in it. LTCM lost money when Russia defaulted on a certain class of bonds, and then they had other investments like on the spread between two different kinds of shares of Royal Dutch Shell Oil Company. Now that seems completely unrelated to Russian bonds. But they were related because other hedge funds saw similar discrepancies and they were all making similar bets. So the world is much more correlated than we give credit to. And so we see more of what Nassim Taleb calls “black swan events”-- rare events happen more often than they should because the world is more correlated. I think one lesson we have to learn is that there’s a lot more risk than we’re giving credit to, a lot more what economist calls systematic risk...
