In this analysis, we examine the effect of wages on obesity by constructing pseudo-panels to conduct a dynamic estimation of Grossman's human capital model. The results indicate that wages have an increasing effect on obesity status. After accounting for past health status, the protective effect of wages commonly disseminated in the literature reverses on obesity status. The results may also indicate possible asymmetric consumption behavior between foods/nutrients that improve diet quality versus those that degrade it. Individuals may be more keen to adhere to prophylactic diet strategies that abate consumption of unhealthy food/nutrients rather than measures which increase healthy nutrient consumption. Additionally, wages have an increasing effect on overall total calories consumed. These findings suggest that higher wage earners may focus their diet efforts on reducing consumption of specific nutrients but compensate by overconsuming other types of nutrients increasing overall calorie intake.

在本分析中,我们通过构建伪面板来动态估计格罗斯曼的人力资本模型,从而研究工资对肥胖的影响。结果表明,工资对肥胖状况有增强效应。在考虑过去的健康状况后,文献中普遍提及的工资对健康的保护作用在肥胖状况上发生了逆转。研究结果还可能表明,在改善饮食质量的食物/营养素与降低饮食质量的食物/营养素之间,可能存在不对称的消费行为。个体可能更热衷于坚持预防性饮食策略,即减少不健康食物/营养素的消费,而不是增加健康营养素消费的措施。此外,工资对总体卡路里摄入量有增强效应。这些发现表明,高收入者可能将饮食方面的努力集中在减少特定营养素的消费上,但会通过过度消费其他类型的营养素来进行补偿,从而增加总体卡路里摄入量。版权所有© 2017约翰·威利父子有限公司。
