Family income is a positive predictor of children's health, human capital, and later-life earnings, but determining the extent to which these associations reflect causal effects is challenging. A recent wave of natural and randomized experiments, together with increased accessibility of large-scale administrative data, are allowing us to gain new perspectives about the importance of families' monetary resources in the U.S. and other high-income countries. This review pulls the emerging literature together to provide deeper insights into what we know, and what we don't know, about the extent to which policies that provide more generous income transfers could make a difference to children's life chances. My reading of the evidence suggests that policies providing financial resources to economically vulnerable families have the potential to improve children's outcomes. The magnitude of predicted impacts varies considerably across studies, however, and may be related to specific features of the income-generating event that researchers' leverage.

We examine multi-generational impacts of positive in utero health interventions using a new research design that exploits sharp increases in prenatal Medicaid eligibility that occurred in some states. Our analyses are based on U.S. Vital Statistics Natality files, which enables linkages between individuals' early life Medicaid exposure and the next generation's health at birth. We find evidence that the health benefits associated with treated generations' early life program exposure extend to later offspring. Our results suggest that the returns on early life health investments may be substantively underestimated.
