In What Was I Thinking, the New Yorker reviews two books on behavioral economics: “Predictably Irrational: The Hidden Forces That Shape Our Decisions” by Dan Ariely and “Nudge: Improving Decisions About Health, Wealth, and Happiness” by Richard H. Thaler and Cass R. Sunstein.
The New York Times also discusses Nudge and the idea of soft paternalism the book supports in A Nudge (or Is it a Shove?) To the Unwise: “For the case against nudges, see “Paternalism and Psychology,” (PDF) an essay by the Harvard economist Edward Glaeser. For the case in favor, see “Nudge” or this essay by Mr. Sunstein and Dr. Thaler.”
Another article in the New York Times, Are We Ready to Track Carbon Footprints?, discusses Nudge in relation to climate change. Here is an extract:
“The authors of “Nudge,” Cass Sunstein and Richard Thaler of the University of Chicago, agree with economists who’d like to reduce greenhouse gas emissions by imposing carbon taxes or a cap-and-trade system, but they think people need extra guidance. Getting the prices right will not create the right behavior if people do not associate their behavior with the relevant costs,” says Dr. Thaler, a professor of behavioral science and economics. “When I turn the thermostat down on my A-C, I only vaguely know how much that costs me. If the thermostat were programmed to tell you immediately how much you are spending, the effect would be much more powerful. It would be still more powerful, he and Mr. Sunstein suggest, if you knew how your energy consumption compared with the social norm.” read more
