Research Summary

I am nationally and internationally recognized as an expert on the economics of tobacco and have been conducting studies related to costs of smoking and secondhand smoke exposure for over 25 years. My research team was one of the first groups to develop econometric models of smoking-attributable costs, and these models represent the state-of-the-art today. We have refined and improved these models and have used them to study lifetime smoking-attributable costs, smoking-attributable costs to Medicaid and Medicare, costs to each of the states and to each of California's counties, costs to Hispanics and Blacks, and the impact of tobacco control expenditures on healthcare expenditures in California. I am involved in ongoing research studying the economic cost of secondhand smoke exposure in California, the US, and China. I am also currently working on the development of economic cost models for other tobacco products. I served as an expert witness for 12 states in litigation that the Attorneys General brought against the tobacco industry to recover Medicaid costs. I was also an expert witness for similar litigation on behalf of Blue Cross Blue Shield. I regularly present my research on the economics of tobacco at national and international conferences and at tobacco control forums, and I have testified before the California legislature. I have also conducted research related to economic effects of tobacco use on health and healthcare costs in India and China. I have mentored a number of postdoctoral fellows, including Dr. John, who studied the cost of smoking in India, Dr. Yao, who has worked with me on the economic impact of secondhand smoke in rural China and tobacco purchasing behavior in China, Dr. Lindsay who worked with me on secondhand exposure of smokers, and Dr. Chambers, who is working with me on the economic impact of tobacco policies within the context of healthcare utilization among vulnerable populations with chronic disease. I have co-authored papers with all of my fellows.
