School meals provide nourishment to a large portion of US schoolchildren. Research has examined the relationship between the consumption of school meals and the quality of schoolchildren's diets, with little emphasis on studying spillovers at the household level. Using National Food Acquisition and Purchase Survey data and unconditional quantile regression, we study the relationship between a household's quality of food-at-home acquisitions and the number of school meals acquired, subsampling households by their Supplemental Nutrition Assistance Program participation status. We do not find strong evidence supporting beneficial spillovers of school meals on a household's quality of food-at-home acquisitions.

学校膳食和家庭食品采购质量

学校供餐为大部分美国学童提供营养。研究检查了学校膳食消费与学童饮食质量之间的关系，很少强调研究家庭层面的溢出效应。使用全国食品采购调查数据和无条件分位数回归，我们研究了家庭的家庭食品采购质量与获得的学校膳食数量之间的关系，并根据补充营养援助计划的参与状况对家庭进行了二次抽样。我们没有发现有力的证据支持学校供餐对家庭购买食物质量的有益溢出。
