A positive relationship between income and child outcomes has been observed in data from numerous countries. A key question concerns the extent to which this association represents a causal relationship as opposed to unobserved heterogeneity. We use data from the National Longitudinal Survey of Children and Youth to implement a series of empirical strategies for estimating the existence and size of the effect of income on behavioural-emotional outcomes. We also examine the role of parenting style. Our results indicate that there is little evidence of an effect of income on behavioural-emotional scores. The exclusion of parenting style from the models was found to not bias the estimated income effect, but parenting style was found to have a consistent impact on child outcomes.
在许多国家的数据中都观察到了收入与儿童成长结果之间的正相关关系。一个关键问题是，这种关联在多大程度上代表因果关系，而非未观察到的异质性。我们使用来自全国儿童和青少年纵向调查的数据，实施了一系列实证策略，以估计收入对行为-情绪结果的影响的存在与否及大小。我们还研究了养育方式的作用。我们的结果表明，几乎没有证据表明收入对行为-情绪得分有影响。研究发现，从模型中排除养育方式并不会使估计的收入效应产生偏差，但养育方式对儿童成长结果有持续影响。
