We continue the topic of last month's Cool Friends interview with the latest addition. Once again, Behavioral Economics is the subject of discussion with our new Cool Friend, Richard Thaler. Many people say that he invented the discipline. Thaler is Professor of Economics and Behavioral Science at the Graduate School of Business, University of Chicago, and Director of the GSB's Center for Decision Research. Earlier this year, he and coauthor Cass Sunstein wrote Nudge: Improving Decisions about Health, Wealth, and Happiness. Erik interviews Richard to find out the difference between a nudge and a noodge, what a choice architect is, and whether libertarian paternalism is an oxymoron. Thaler wants to help people make better choices. That’s why we think you might want to read his Cool Friends interview. You can also explore the website, Nudges.org, or the blog of the same name.
