本文利用自然实验估计了收入对美国老年人体重和临床体重分类的影响，该实验导致其他相同的退休人员根据出生年份获得显着不同的社会保障金。我们使用全国健康访谈调查的数据估计工具变量模型，发现收入对体重没有显着影响。置信区间甚至排除了收入对体重以及体重过轻或肥胖的可能性的中等影响，尤其是对于男性而言。例如，他们指出，体重指数的收入弹性绝对值不大于男性0.06或女性0.14。版权所有 (C) 2009 John Wiley & Sons, Ltd.
This paper estimates the impact of income on the body weight and clinical weight classification of elderly Americans using a natural experiment that led otherwise identical retirees to receive significantly different Social Security payments based on their year of birth. We estimate models of instrumental variables using data from the National Health Interview Surveys and find no significant effect of income on weight. The confidence intervals rule out even moderate effects of income on weight and on the probability of being underweight or obese, especially for men. For example, they indicate that the income elasticity of body mass index is not greater in absolute value than 0.06 for men or 0.14 for women. Copyright (C) 2009 John Wiley & Sons, Ltd.
