We review existing research and policy evidence about income as an essential component to meeting children's basic needs-that is, income represented as the purest monetary transfer for increasing the purchasing power of low income families. Social scientists have made great methodological strides in establishing whether income has independent effects on the cognitive development of low-income children. Our review of that research suggests that a $1,000 increase in income has positive, but small, effects on children, rarely exceeding 1/10(th) of a standard deviation change in outcomes for children. We argue that researchers are well-positioned for more rigorous investigations about how and why income affects children, but only first with thoughtful and creative regard for conceptual clarity, and on understanding income's potentially inter-related influences on socio-emotional development, mental, and physical health. We also argue for more focus on the effects of income transfers, including when conditional on employment, as compared to more targeted direct investments in children. We end with a description of two-generation and cafeteria-style programs as the frontiers of the next generation in income-enhancement policies, and with the promise of insights from behavioral economics.
我们回顾了现有关于收入作为满足儿童基本需求的重要组成部分的研究和政策证据,即收入表现为用于提高低收入家庭购买力的最纯粹货币转移。社会科学家在确定收入是否对低收入儿童的认知发展有独立影响方面取得了巨大的方法学进展。我们对该研究的回顾表明,收入增加1000美元对儿童有积极但微小的影响,很少超过儿童结果标准差变化的十分之一。我们认为,研究人员有能力对收入如何以及为何影响儿童进行更严格的调查,但首先要对概念清晰度进行深思熟虑和富有创造性的思考,并理解收入对社会情感发展、心理和身体健康的潜在相互关联影响。我们还主张更多地关注收入转移的影响,包括以就业为条件时的影响,与对儿童更有针对性的直接投资相比。我们最后描述了两代人计划和自助式计划,它们是下一代收入增强政策的前沿领域,并有望从行为经济学中获得见解。
