中文摘要
既有研究发现，食品支出在退休时下降，这表明家庭储蓄不足。相反，其他证据显示，食品摄入的直接衡量指标并不受退出劳动力市场的影响。利用广泛的数据来源和方法，我们发现食品摄入在退休时下降，具体表现为：在跨越40年的横截面数据集中，热量和营养摄入下降；利用纵向数据发现热量摄入减少；以及一个将饮食构成与永久收入联系起来的食品摄入指数下降。我们在消费生命周期模型的背景下讨论了这些结果的含义。(JEL D15, G51, I12, J26)
Abstract
Prior research finds food expenditure decreases at retirement, which suggests households are inadequately saving. In contrast, other evidence shows that direct measures of food intake are unaffected by exiting the labor force. Using a wide array of data sources and methodologies, we find that food intake falls at retirement, including: declines in caloric and nutrient intake in cross-sectional datasets spanning 40 years, a decrease in caloric intake using longitudinal data, and a drop in a food intake index that relates diet composition to permanent income. We discuss the implications of these results in the context of life-cycle models of consumption. (JEL D15, G51, I12, J26)
