英文文献摘要：
The main goal of this paper is to provide current information on the impacts of Supplemental Nutrition Assistant Program (SNAP) on food spending across two food subgroups: food at home (FAH) and food away from home (FAFH). Data was obtained from the BLS?s Consumer Expenditure Survey and Detailed Monthly Consumer Price Indices from years 1998 to 2009. Censoring of expenditures and the endogeneity of the SNAP participation variable are accounted for with the use of specialized econometric procedures. We found that SNAP participation increases FAH by $25 and decreases expenditures on food away from home by $32. Since the average SNAP benefits received by participants in the program is $80, the marginal propensity to consume of food at home out of SNAP benefits is 0.31.

本文的主要目的是提供关于补充营养助理计划(SNAP)对两个食品亚群的食品支出影响的最新信息:在家食品(FAH)和在外食品(FAFH)。数据来源于1998年至2009年劳工统计局的消费者支出调查和详细的月度消费者价格指数。支出的审查和SNAP参与变量的内生性是用专门的计量经济学程序来解释的。我们发现，SNAP参与增加了25美元的FAH，减少了32美元的外出食品支出。由于该计划参与者获得的SNAP福利平均为80美元，扣除SNAP福利后的家庭边际食品消费倾向为0.31。
