Does Money Matter?
研究美国和英国的家庭收入对儿童认知、行为和社会评估得分的影响，发现收入虽有显著正向作用，但效应大小相对于其他家庭背景变量较小。
Abstract In this paper, we examine the effect of income on child development in the United States and the United Kingdom, as measured by scores on cognitive, behavioral, and social assessments. In line with previous results for the United States, we find that for both countries income generally has an effect on child development that is positive and significant, but whose size is small relative to other family background variables.
