Despite substantial evidence that resources and outcomes are transmitted across generations, there has been limited inquiry into the extent to which antipoverty programs actually disrupt the cycle of bad outcomes. We leverage the rollout of the United States’s largest early-childhood program, Head Start, to estimate the effect of early-childhood exposure among mothers on their children’s long-term outcomes. We find evidence of intergenerational transmission of effects in the form of increased educational attainment, reduced teen pregnancy, and reduced criminal engagement in the second generation. These effects correspond to an estimated increase in discounted second-generation wages of 6%–11%, depending on specification. Exploration of earlier outcomes suggests an important role for changes in parenting behavior and potential noncognitive channels.

We provide new evidence that cash transfers following the birth of a first child can have large and long-lasting effects on that child’s outcomes. We take advantage of the January 1 birthdate cutoff for U.S. child-related tax benefits, which results in families of otherwise similar children receiving substantially different refunds during the first year of life. For the average low-income single-child family in our sample, this difference amounts to roughly $1,300, or 10% of income. Using the universe of administrative federal tax data in selected years, we show that this transfer in infancy increases young adult earnings by at least 1%–2%, with larger effects for males. These effects show up at earlier ages in terms of improved math and reading test scores and a higher likelihood of high-school graduation. The observed effects on shorter-run parental outcomes suggest that additional liquidity during the critical window following the birth of a first child leads to persistent increases in family income that likely contribute to the downstream effects on children’s outcomes. The longer-term effects on child earnings alone are large enough that the transfer pays for itself through subsequent increases in federal income tax revenue.
