本文评估了学校午餐是否会导致儿童肥胖。我采用两种方法来隔离学校午餐对肥胖的因果影响。首先，使用面板数据，我发现，谁消耗学校午餐的儿童更容易肥胖比那些棕色袋他们的午餐，即使他们进入幼儿园与相同的肥胖率。其次，我利用减价午餐资格的急剧不连续性来比较刚刚高于和低于资格截止的儿童。学生们更容易肥胖，如果他们有收入资格享受减价的学校午餐，他们的体重会更重。
This paper assesses whether school lunches contribute to childhood obesity. I employ two methods to isolate the causal impact of school lunches on obesity. First, using panel data, I find that children who consume school lunches are more likely to be obese than those who brown bag their lunches even though they enter kindergarten with the same obesity rates. Second, I leverage the sharp discontinuity in eligibility for reduced-price lunch to compare children just above and just below the eligibility cutoff. Students are more likely to be obese, and weigh more if they are income-eligible for reduced price school lunches.
