The Institute on Health Economics, Health Behaviors and Disparities (HEHBAD) supports and strengthens the intellectual community at Cornell studying health economics, in particular the economics of health behaviors such as smoking, alcohol abuse, drug use, risky sex, diets and sedentary lifestyles that contribute to obesity. Activities of the Institute include a weekly lunchtime research seminar, course sequences at both the Ph.D. and advanced undergraduate levels, and hosting visiting scholars. The Institute, co-directed by John Cawley and Don Kenkel, is operationally housed within Policy Analysis and Management.
