We examine the role that an exogenous increase in household income due to a government transfer unrelated to household characteristics plays in children's long run outcomes. Children in affected households have higher levels of education in their young adulthood and a lower incidence of criminality for minor offenses. Effects differ by initial household poverty status. An additional $4000 per year for the poorest households increases educational attainment by one year at age 21 and reduces having ever committed a minor crime by 22% at ages 16−17. Our evidence suggests that improved parental quality is a likely mechanism for the change.

Despite clear evidence of a sharp income gradient in voting participation, it remains unclear whether income truly causes voting. In this article, we investigate how exogenous increases in unearned income affect voting in U.S. elections for two generations (parents and children) from the same household. In contrast to predictions made by current models of voting, we find the income shock had no effect on parents' voting behaviors. However, we also find that increasing household income has heterogeneous effects on the civic participation of children from different socioeconomic backgrounds. It increases children's voting propensity among those raised in initially poorer families—resulting in substantially narrowed participatory gaps. Our results are consistent with a more nuanced view of how individual resources affect patterns of voting than the dominant theoretical framework of voting—the resource model—allows. Voting is fundamentally shaped by the human capital accrued long before citizens are eligible to vote.

We examine the effects of a quasi-experimental unconditional household income transfer on child emotional and behavioral health and personality traits. Using longitudinal data, we find that there are large beneficial effects on children's emotional and behavioral health and personality traits during adolescence. We find evidence that these effects are most pronounced for children who start out with the lowest initial endowments. The income intervention also results in improvements in parental relationships which we interpret as a potential mechanism behind our findings. (JEL D14, I12, I26, I31, I38, J13, J15)

Identifying the effect of parental incomes on child outcomes is difficult due to the correlation of unobserved ability, education levels and income. Previous research has relied on the use of instrumental variables to identify the effect of a change in household income on the young adult outcomes of the household´s children. In this research, we examine the role that an exogenous increase in household incomes due to a government transfer unrelated to household characteristics plays in the long run outcomes for children in affected households. We find that children who are in households affected by the cash transfer program have higher levels of education in their young adulthood and a lower incidence of criminality for minor offenses. These effects differ by initial household poverty status as is expected. Second, we explore two possible mechanisms through which this exogenous increase in household income affects the long run outcomes of children - parental time (quantity) and parental quality. Parental quality and child interactions show a marked improvement while changes in parental time with child does not appear to matter.

AbstractCan positive transitions into young adulthood at age 25 prevent problematic substance use at age 31, even in the context of childhood adverse family environments, conduct problems, and adolescent substance use? We lean on John Schulenberg's developmental framework to examine this question, focusing on the potential young adult milestones of high school and college graduation, employment, residential independence, romantic partnership, and parenthood. Data came from a prospective‐longitudinal multi‐method study with N = 1199 participants who were first assessed at age 5 years old and followed to age 31. An accumulation of positive transitions in young adulthood (age 25) was associated with lower likelihood of age 31 problematic cannabis use. The protective effect for problematic cannabis use remained even when adjusting for childhood adverse family environments and was primarily driven by successful college graduation and/or home ownership. The accumulation of positive transitions protected individuals at modest to somewhat elevated risk due to childhood adverse family environments from experiencing age 31 cannabis use problems. However, for other individuals with very high numbers of conduct problems, or with high levels of adolescent substance use, the protective effects of accumulated positive transitions to young adulthood were less strong or nonexistent. Moreover, individuals who completed college or obtained full‐time employment by 25 were more likely to report problematic age 31 alcohol use. These findings highlight the central tenets of John Schulenberg's developmental framework, including the examination of ontogenetic continuity and discontinuity, the interplay of developmentally distal and proximal effects, and the identification of developmental protective factors that may sway people toward or away from substance use.

Recent research links disparities in children's language-related brain function to poverty and its correlates. Such disparities are hypothesized to underlie achievement gaps between students from low-income families and more advantaged peers. Interventions that improve language-related brain function in low-income students exist, but evaluations of their implementation within high-poverty elementary schools do not. This comparison-group study evaluates whether implementation within high-poverty elementary schools of Harmony Project music-based mentoring, previously shown in randomized controlled research to improve language-related brain function and literacy in low-income students, might be associated with academic improvement for participants compared with non-participating peers. Standardized academic achievement scores were evaluated retrospectively for 2nd graders who opted into or out of Harmony Project (HP) at baseline (nHP = 218; nnon-HP = 862) for weekly music-based mentoring over 2 years. Adjusting for baseline scores, HP participation was associated with higher standardized scores for math (+17 points; ß = .06, p = .02) and English language arts (+26 points; ß = .08, p = .002). Importantly, students with the lowest prior achievement scores showed the greatest gains for both math (+33 points; ß =.13, p =.02) and English language arts (+39 points; ß =.14, p =.02). Implementation within high-poverty elementary schools of a program previously found to improve language-related brain function in low-income students was associated with significant academic improvement for participants, particularly those with the lowest prior levels of achievement. Findings support the hypothesis that disparities in children's language-related brain function linked to poverty and its correlates may underlie achievement gaps.

The importance of including developmental and environmental measures in genetic studies of human pathology is widely acknowledged, but few empirical studies have been published. Barriers include the need for longitudinal studies that cover relevant developmental stages and for samples large enough to deal with the challenge of testing gene–environment–development interaction. A solution to some of these problems is to bring together existing data sets that have the necessary characteristics. As part of the National Institute on Drug Abuse-funded Gene-Environment-Development Initiative, our goal is to identify exactly which genes, which environments, and which developmental transitions together predict the development of drug use and misuse. Four data sets were used of which common characteristics include (1) general population samples, including males and females; (2) repeated measures across adolescence and young adulthood; (3) assessment of nicotine, alcohol, and cannabis use and addiction; (4) measures of family and environmental risk; and (5) consent for genotyping DNA from blood or saliva. After quality controls, 2,962 individuals provided over 15,000 total observations. In the first gene–environment analyses, of alcohol misuse and stressful life events, some significant gene–environment and gene–development effects were identified. We conclude that in some circumstances, already collected data sets can be combined for gene–environment and gene–development analyses. This greatly reduces the cost and time needed for this type of research. However, care must be taken to ensure careful matching across studies and variables.
