The School Breakfast Program (SBP) and National School Lunch Program (NSLP) are two federally assisted school meal programs that currently serve over 31.7 million children each day. Most of the existing literature examines the nutritional quality of school meals with a handful studying the impacts on child weight. A couple of studies also examine whether SBP has impacts on academic performance, and, to our knowledge, no studies examine the direct or indirect effects of NSLP participation on performance. Using full-information maximum likelihood, we simultaneously estimate the child weight and academic performance production functions along with child choice equations and program participation equations to examine potential spillover effects of SBP and NSLP on academic performance through the mediator of child weight. Results do show spillover effects on 8th grade math and English scores with particularly large impacts on FRP eligible participants: negative impacts of NSLP participation and positive impacts of SBP participation on achievement.

学校早餐计划(SBP)和国家学校午餐计划(NSLP)是两个由联邦政府资助的学校膳食计划，目前每天为3170多万儿童提供服务。大多数现有的文献调查了学校膳食的营养质量和少数研究对儿童体重的影响。有几项研究也考察了SBP是否对学习成绩有影响，据我们所知，没有研究考察NSLP参与对学习成绩的直接或间接影响。利用全信息最大似然，我们同时估计了儿童体重和学习成绩产生函数以及儿童选择方程和项目参与方程，以通过儿童体重这一中介来检验SBP和NSLP对学习成绩的潜在溢出效应。结果显示，八年级数学和英语成绩的溢出效应对FRP合格参与者的影响尤其大:NSLP参与的负影响和SBP参与对成绩的正影响。
