In the past three decades, the number of obese adults in the US has doubled and the number of obese children almost tripled. This text provides a strong foundation for evaluating the costs and benefits of various proposals designed to control obesity rates.

"I discuss economic approaches to the demand for harmfully addictive substances and estimate time-series demand functions for the period from 1975 through 2003. My estimates suggest that changes in price can explain a good deal of the observed changes in cigarette smoking, binge alcohol drinking, and marijuana use by high school seniors. For example, the 70 percent increase in the real price of cigarettes since 1997 due to the Medicaid Master Settlement Agreement explains almost all of the 12 percentage point reduction in the cigarette smoking participation rate since that year. The 7 percent increase in the real price of beer between 1990 and 1992 due to the Federal excise tax hike on that beverage in 1991 accounts for almost 90 percent of the 4 percentage point decline in binge drinking in the period at issue. The wide swings in the real price of marijuana explain 70 percent of the reduction in particpation from 1975 to 1992, 60 percent of the subsequent growth to 1997, and almost 60 percent of the decline since that year. I conclude with implications for tax policy and for the lively and contentious debate concerning the legalization of marijuana, cocaine, and heroin"--National Bureau of Economic Research web site.

"I explore the effects of education on nonmarket outcomes from both theoretical and empirical perspectives. Examples of outcomes considered include general consumption patterns at a moment in time, savings and the rate of growth of consumption over time, own (adult) health and inputs into the production of own health, fertility, and child quality or well-being reflected by their health and cognitive development. I pay a good deal of attention to the effects of education on health because they are the two most important sources of human capital: knowledge capital and health capital. There is a large literature addressing the nature of their complementarities. In the conceptual foundation section, I consider models in which education has productive efficiency and allocative efficiency effects. I then modify these frameworks to allow for the endogenous nature of schooling decisions, so that observed schooling effects can be traced in part to omitted "third variables" such as an orientation towards the future. An additional complication is that schooling may contribute to a future orientation. The empirical review provides a good deal of evidence for the proposition that the education effects are causal but is less conclusive with regard to the identification of specific mechanisms"--National Bureau of Economic Research web site.

The purpose of this research is to investigate empirically the determinants of children's health with particular reference to home and local environmental variables such as family income, parents' schooling, preventive medical care, and health manpower availability. Wherever possible, children's health is studied in the context of the nature-nurture controversy. The findings indicate that family characteristics (especially mother's schooling) do have significant impacts on children's health and that preventive care is an important vehicle for this impact in the case of dental health but not in the case of physical health. Similarly, the greater availability of dentists has a positive impact on dental health, but greater availability of pediatricians does not alter the physical health measures.

This volume focuses on human capital and health behavior. Content is based on an International symposium on Human Capital and Health Behavior, held by The Centre for Health Economics at the University of Gothenburg. Content will cover both theoretical and empirical aspects of the topic.

"The purpose of this paper is to examine the role of alcohol policies in reducing the incidence of sexually transmitted diseases among youth. Previous research has shown that risky sexual practices (e.g., unprotected sex and multiple partners) that increase the risk of contracting a STD are highly correlated with alcohol use. If alcohol is a cause of risky sexual behavior, then policies that reduce the consumption of alcohol may also reduce the incidence of STDs. In this paper, we examine the relationship between alcohol policies (e.g., beer taxes and statutes pertaining to alcohol sales and drunk driving) and rates of gonorrhea and AIDS among teenagers and young adults. Results indicate that higher beer taxes are associated with lower rates of gonorrhea for males and are suggestive of lower AIDS rates. Strict drunk driving policies in the form of zero tolerance laws may also lower the gonorrhea rate among males under the legal drinking age"--National Bureau of Economic Research web site.
