The Effect of Income on Child Development
估计了父母收入对儿童认知、社交和情感发展的影响，发现当前收入影响很小，永久收入影响较大但相对政策变化仍较小，家庭背景比收入更重要。
This study presents estimates of the effect of parental income on children's cognitive, social, and emotional development. The effect of current income is small, especially when income is treated as endogenous. The effect of “permanent” income is substantially larger, but relatively small when compared to the magnitude of recent policy-induced changes in income. Family background characteristics play a more important role than income in determining child outcomes. Policies that affect family income will have little direct impact on child development unless they result in very large and permanent changes in income. © 1999 by the President and Fellows of Harvard College and the Massachusetts Institute of Technology
