在父母收入对子女成就的因果影响的大小和性质上,社会科学家们意见不一。我们通过在20世纪90年代进行的一系列福利和反贫困实验来重新审视这一问题。我们利用工具变量策略来利用随机分配给治疗组所产生的收入和成就的差异来估计收入对儿童成就的因果影响。我们的估计表明,年收入每增加1,000美元,幼儿的成绩就会增加5%-6%的标准差。因此,我们的结果表明,家庭收入对学龄前儿童最终的学业成绩具有政策相关的积极影响。
Social scientists do not agree on the size and nature of the causal impacts of parental income on children's achievement. We revisit this issue using a set of welfare and antipoverty experiments conducted in the 1990s. We utilize an instrumental variables strategy to leverage the variation in income and achievement that arises from random assignment to the treatment group to estimate the causal effect of income on child achievement. Our estimates suggest that a $1,000 increase in annual income increases young children's achievement by 5%–6% of a standard deviation. As such, our results suggest that family income has a policy-relevant, positive impact on the eventual school achievement of preschool children.
