The demand for health and health concerns after 30 years.

Michael Grossman's seminal model stressed that health production requires both goods and time. Yet recent empirical health research focuses primarily on personal medical care to the exclusion of other inputs to health. Future research should place greater emphasis on the roles of non-medical consumption goods, population level inputs and time in producing health capital. Improved information technology will allow researchers to dissect how education promotes efficiency in combining goods and time to produce health. Economic analyses of child health, which is the antecedent of adult health, must proceed in tandem with medical advances in understanding health development in childhood.
