It is believed that income affects health directly but it is argued that indirect income effects due to relative deprivation may be equally important. This paper investigates these relationships using parametric and semiparametric panel data models which ameliorate problems of mis-specification and unobservable heterogeneity. By allowing for a flexible functional form of income we ensure that coefficients on relative deprivation variables are not an artefact of a highly non-linear relationship between health and income. The results provide strong evidence for the impact of income on self-reported measures of health for men and women. These results are robust across a range of techniques and are resilient to the inclusion of measures of relative deprivation. The parametric results for relative deprivation largely reject its influence on health, although there is some evidence of an effect in the semiparametric models.
人们认为收入直接影响健康，但也有人认为，由于相对剥夺造成的间接收入影响可能同样重要。本文使用参数和半参数面板数据模型研究这些关系，这些模型改善了错误设定和不可观测的异质性问题。通过允许收入采用灵活的函数形式，我们确保相对剥夺变量的系数不是健康与收入之间高度非线性关系的人为产物。结果为收入对男性和女性自我报告的健康指标的影响提供了有力证据。这些结果在一系列技术中都很稳健，并且对纳入相对剥夺指标具有弹性。相对剥夺的参数结果在很大程度上否定了其对健康的影响，尽管在半参数模型中有一些影响的证据。
