Mortality, family and lifestyles

Abstract

While there is a large empirical literature on the intergenerational transmission of health and survival outcomes in relation to lifestyles, little theoretical work exists on the long-run prevalence of (un)healthy lifestyles induced by mortality patterns. To examine that issue, this paper develops an overlapping generations model where a healthy lifestyle and an unhealthy lifestyle are transmitted vertically or obliquely across generations. It is shown that there must exist a locally stable heterogeneous equilibrium involving a majority of healthy agents, as a result of the larger parental gains from socialization efforts under a higher life expectancy. Wealso examine the robustness of our results to the introduction of parental altruistic concerns for children's health and of asymmetric socialization costs.altruism ; family ; lifestyle ; longevity ; socialization
