Center for Health Incentives and Behavioral Economics Research

CHIBE researchers apply concepts from the field of behavioral economics to design, implement, and evaluate interventions that improve health and build knowledge about efficacy, cost and effectiveness. 

Basic Science Core Request for Applications

The Basic Science Core aims to support laboratory or low-cost field studies that will shed light on mechanisms that can generate behavior change.  In contrast to previous large-scale field studies, which have often combined multiple mechanisms into one intervention in order to maximize impact on behavior, basic science projects supported by the Core focus on disentangling and precisely identifying the impacts of individual mechanisms.  CHIBE researchers interested in applying for project support can click here for more information.

Making Calories Count: Information Format and Food Choice

Principal Investigators:  Downs / Loewenstein

Government policy aimed at promoting healthy eating habits has tended toward strategies based on information provision, though there is little evidence that this strategy is maximally effective. This pilot study involves a cross-sectional test of the impact of calorie labeling and a heuristic cue on customers' choice of lunch item on-site at a chain restaurant, as well as a cohort study which assesses lunch item choices over time based on real-time nutritional feedback.
