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.

A Randomized Trial of Cognitive vs. Behavioral Incentives to Induce Sustained Healthy Oral Hygiene Habits and Improve Oral Health

Principal Investigators: Alison Buttenheim, PhD, MBA and Iwan Barankay, PhD

Designing cost-effective, time-limited interventions that lead to persistent healthy habits is a pressing public health challenge. In this planned randomized controlled study, we propose to test and compare the effectiveness of two types of financial incentives-behavioral vs. cognitive-for creating better toothbrushing habits and improving the gingival index, an important measure of oral health.

Project LIFT: Lifestyle intervention to promote fitness in transplantation

Principal Investigators: Marina Serper, MD, MS; Iwan Barankay, PhD; Peter Reese, MD

Objectives: 1) To determine whether use of an accelerometer device (Misfit tracker) and financial loss-incentives paired with health trivia information vs. the accelerometer use alone increases walking among kidney and liver transplant recipients, and 2) To evaluate whether the interventions are associated with lower weight and changes in body fat composition.

Testing Behavioral Economic Interventions to Improve Statin Use and Reduce CVD Risk

Principal Investigators: Kevin Volpp, Iwan Barankay, Peter Reese

The application of conceptual approaches from behavioral economics offers considerable promise in advancing health and health care. In patients with suboptimal cholesterol control who are at high risk for CVD, this study will test the effectiveness and cost-effectiveness of different behavioral economic techniques to improve statin adherence following discontinuation of the intervention. Investigative team leaders Iwan Barankay, Kevin Volpp and Peter Reese will use a 4-arm randomized controlled trial to compare the effectiveness and cost effectiveness of alternative approaches to inducing habit formation among CVD patients with poorly controlled cholesterol who have been prescribed statins.

Rankings and Social Tournaments: Evidence from a Field Experiment

Principal Investigator: Barankay 

Exploration of whether telling how individuals rank in terms of performance compared to their peers affects productivity in a context where ranking has no impact on monetary compensation.
