Professor David R. Just uses the tools of psychology and economics to examine how individuals approach choices ranging from whether to complete a costly business merger to what to have for lunch. As the director of the Cornell Center for Behavioral Economics in Child Nutrition Programs, David has conducted dozens of field and laboratory experiments identifying the subtle factors in the environment that can lead both children and adults to make the healthy choice. His work on behavioral economics and the school lunch program has shown how low cost solutions—like moving the salad bar closer to the checkout line—can lead school children to make healthier choices without reducing overall availability of choices, or breaking the school budget. Other work has examined how individuals or corporations use information to inform risky investments, and how this information can be used to ones advantage.
David's award winning research has been published in scores of research articles, winning wide recognition both among academics and within the popular press. His work has been reported in numerous media outlets including the NPR, Wall Street Journal, New York Times, US News and World Reports, Newsweek, Washington Post among many others.
