What is a nudge and how long do they last?

Walgreen Distinguished Service Professor of Behavioral Science and Economics at the University of Chicago Booth School of Business. He is the New York Times bestselling co-author of Nudge: Improving Decisions About Health, Wealth, and Happiness and the author of Misbehaving: The Making of Behavioral Economics. His new book is The Winner's Curse: Behavioral Economics Anomalies, Then and Now.
