This paper tests for income-related reporting heterogeneity in self-assessed health (SAH). It also constructs a synthetic measure of clinical health to decompose the effect of income on SAH into an effect on clinical health (which is called a health production effect) and a reporting heterogeneity effect. We find health production effects essentially for low-income individuals, and reporting heterogeneity for the choice between the medium labels, i.e. 'fair' vs 'good' and for high-income individuals. As such, SAH should be used cautiously for the assessment of income-related health inequalities in France. It is however possible to minimize the reporting heterogeneity bias by converting SAH into a binary variable for poor health vs other health statuses.
本文检验了自我评估健康（SAH）中与收入相关的报告异质性。它还构建了一个临床健康的综合指标，以将收入对SAH的影响分解为对临床健康的影响（称为健康生产效应）和报告异质性效应。我们发现，低收入个体主要存在健康生产效应，而中等标签（即“一般”与“良好”）之间的选择存在报告异质性，高收入个体也存在报告异质性。因此，在法国，应谨慎使用SAH来评估与收入相关的健康不平等。然而，通过将SAH转换为健康状况不佳与其他健康状况的二元变量，可以将报告异质性偏差降至最低。
