Willard Manning, Ph.D.
Willard G. Manning is a Professor Emeritus in the Harris School of Public Policy and in the Department of Health Studies in the Division of the Biological Sciences. Manning’s primary area of interest has been the effects of health insurance. He has studied the demand for various health services under both fee-for-service cost-sharing and prepaid insurance, as well as the impact on the appropriateness of care and health status. He was one of the senior investigators on the RAND Health Insurance Experiment, a randomized trial of alternative insurance plans conducted from 1974-1982. He has examined the health effects of insuring the formerly uninsured when the near-elderly become Medicare-eligible at age 65. In recent work, he has examined the optimal insurance coverage for preventive care and treatment, considering the trade-off between the costs from moral hazard and the gains from risk-pooling across medical services and over time in health insurance.
Manning has also examined statistical, measurement, and economic issues in modeling the use of health services and health care expenditures. Recently he has been developing a robust method for dealing with cost data in the presence of right censoring in time, as well as distinguishing overfitting from misspecification of the model estimated. His past research interests further include the economics of poor health habits, such as smoking and heavy drinking.
Dr. Manning has received the award for best article of the year from the Association for Health Services Research in 1990 for his article on the external costs of smoking and drinking (Manning, et al., JAMA 1989) and in 1993 for two articles from the Medical Outcome Study on differences in costs across medical specialties (Greenfield et al., JAMA 1992; and Kravitz et al, JAMA 1992). He received the Kenneth Arrow Prize for best health economics article for 2001 for his paper on alternative estimators for health care costs (Manning and Mullahy, Journal of Health Economics, 2001). In 2009, he received the Distinguished Investigator Award at the annual meeting of Academy Health, the professional society for health services research in the United States. In 2010, he received the Victor Fuchs Lifetime Achievement Award from the American Society of Health Economists.
Manning is a member of the Institute of Medicine. He has served on IOM committees addressing the lack of insurance, health care at the end of life. He is currently serving on a National Academy of Science panel considering adding measures of medical risk to new poverty measures.
He received his BS in 1968 from the California Institute of Technology, MA in 1971 from Stanford University, and PhD in 1973 from Stanford University.
