Unlike earlier work in medical economics, which has focused on medical care, these ten papers stress the production and consequences of health itself. They reveal a serious concern with real-world health problems in their investigation of such subjects as infant mortality, life expectancy, morbidity, and disability. These papers are unusual, as well, in bringing to bear on these problems new and powerful theoretical and statistical tools. They draw on, and in some cases are, original sources for new bodies of data. As such, Economic Aspects of Health comprises a useful blend of relevance and rigor.
