Specifically, I ask two questions: What is the evidence regarding whether parental socioeconomic status affects child health? And, what is the evidence relating child health to future outcomes? I show that there is now strong evidence of these links, but that it is difficult to say how large the overall effect of health might be or whether it explains a significant amount of the intergenerational transmission of socioeconomic status. 3 When economists think of " human capital, " they often mean education. A large body of literature has established that investments in education pay off in the form of higher future earnings, and that on average, differences in education can explain a significant fraction of the variation in wages and incomes among adults, as well as variation in many other positive outcomes. But what determines a child's educational success? Most studies point to family background as the number one factor. However, this raises a " chicken and egg " problem. We
