Abstract

Supplemental Nutrition Assistance Program (SNAP) is the cornerstone food assistance program in the United States and has been shown to reduce the risk of food insecurity. Most research on the causal effect of SNAP on food insecurity relies on the 12-month food insecurity scale along with usage of SNAP at any point during the year. However, recent social surveys ask about experiences with food insecurity in the 30 days prior to the survey. In this paper, we examine whether similar protective effects of SNAP against food insecurity are obtained whether using the 30-day or 12-month food insecurity scale using the December Supplement of the Current Population Survey for 2002–2019. Results indicate comparable average treatment effects of SNAP in mitigating food insecurity across both 30-day and 12-month reference periods.

在评估 SNAP 对粮食不安全的影响时,参照期是否重要?
补充营养援助计划(SNAP)是美国的基础食品援助计划,已被证明可以降低食品不安全的风险。关于 SNAP 对粮食不安全的因果影响的大多数研究都依赖于 12 个月的粮食不安全量表以及一年中任何时候 SNAP 的使用情况。然而,最近的社会调查会询问调查前 30 天内的粮食不安全经历。在本文中,我们使用 2002-2019 年《当前人口调查》的 12 月补充资料,研究了无论是使用 30 天还是 12 个月的粮食不安全量表,SNAP 对粮食不安全的保护效果是否相似。结果表明,在 30 天和 12 个月的参照期内,SNAP 在缓解粮食不安全方面的平均治疗效果具有可比性。
