This paper examines ways that families use time to shape their children’s health behaviors. Economists who analyze health often draw on the Grossman model, which posits that individuals derive direct utility from health and that they can produce health capital using a household production process that combines market-purchased inputs such as medical care with household time. Our paper emphasizes the need to be motivated to engage in such self-produced human capital. Parents can prepare their children to make health-enhancing choices as adults by engaging them in sports activities as children, in order to help their children identify exercise activities that the children enjoy, and possibly through the example they set in allocating time to exercise themselves and jointly with the children. The paper also examines ways that children manage their time, particularly during young adulthood when they are old enough to make independent decisions about whether they will spend time exercising. Data on television viewing are used to analyze children’s ability to self-regulate so that time is managed in ways that will enhance health and well-being later in life. Such self-regulation can enhance both educational attainment and health capital, producing the often observed strong empirical association between educational attainment and adult health. The empirical research uses time diary data from the Child Development Supplement, data from the PSID core and the PSID's Transition to Adulthood module. Decisions about health and decisions about time use both have implications for well-being. By examining the intergenerational transmission of healthy behaviors, it is possible to better understand decisions individuals make in adulthood.
