2009年，近15%的美国家庭和40%的近乎贫困的家庭处于食品不安全状态。补充营养援助计划（SNAP）是联邦食品援助计划的基石，是抵御食品相关困难的第一道防线。本文使用工具变量方法来控制选择，测量SNAP在减少粮食不安全方面的有效性。我们的研究结果表明，接受SNAP福利将粮食不安全的可能性降低了大约30%，将非常粮食不安全的可能性降低了20%。
Nearly 15% of all U.S. households and 40% of near-poor households were food insecure in 2009. The Supplemental Nutrition Assistance Program (SNAP) is the cornerstone of federal food assistance programs and serves as the first line of defense against food-related hardship. This paper measures the effectiveness of SNAP in reducing food insecurity using an instrumental variables approach to control for selection. Our results suggest that receipt of SNAP benefits reduces the likelihood of being food insecure by roughly 30% and reduces the likelihood of being very food insecure by 20%.
