The Roots of Health Inequality and the Value of Intrafamily Expertise

Abstract

In the context of Sweden, we show that having a doctor in the family raises preventive health investments throughout the life cycle, improves physical health, and prolongs life. Two quasi-experimental research designs-medical school admission lotteries and variation in the timing of medical degrees-support a causal interpretation of these effects. A hypothetical policy that would bring the same health behavior changes and benefits to all Swedes would close 18 percent of the mortality-income gradient. Our results suggest that socioeconomic differences in exposure to health-related expertise may meaningfully contribute to health inequality.
