The Supplemental Nutrition Assistance Program (SNAP) was modified to mitigate food insecurity faced by low-income families during the pandemic. These changes included enhancement of SNAP benefits via 2020 emergency allotments (EA). Despite the high food price inflation in 2022, 17 states ceased providing EA benefits by end of 2022. The objective of this research is to examine the impact of EA discontinuation on food insufficiency.
Using Household Pulse Survey data from December 2021-January 2023, SNAP participants (n = 57,556) from states that discontinued EA at some point during the study period and those from states that did not discontinue EA were included. The main analyses examined the impact of EA discontinuation on food insufficiency via staggered difference-in-difference models using two-way fixed effects (TWFE) regression. Additional analyses examined this association using Callaway-Sant'Anna approach for difference-in-difference analyses.
Using TWFE, EA discontinuation was significantly associated with increased food insufficiency in the overall sample, as well as in individuals who were non-Hispanic White and Hispanic, and who had annual family incomes of less than $25,000. Investigation of time-varying association of EA termination with food insufficiency suggested that EA discontinuation was significantly associated with greater food insufficiency in the second week following rollback. DiD analyses using Callaway-Sant'Anna approach suggested that states' rollback of EA was significantly associated with higher food insufficiency in non-Hispanic White individuals.
Findings imply that EA discontinuation, amidst the corresponding surge in inflation, could have contributed to increased rates of household food insufficiency.
补充营养援助计划(SNAP)进行了修改,以减轻大流行期间低收入家庭面临的粮食不安全问题。这些变化包括通过 2020 年的紧急拨款(EA)增加 SNAP 福利。尽管 2022 年食品价格大幅通胀,但截至 2022 年底,有 17 个州停止提供 EA 福利。本研究的目的是检验 EA 终止对食物不足的影响。
使用 2021 年 12 月至 2023 年 1 月期间的家庭脉搏调查数据,纳入了在研究期间的某个时间点停止 EA 的州的 SNAP 参与者(n=57556)和没有停止 EA 的州的 SNAP 参与者。主要分析使用双向固定效应(TWFE)回归的交错差分差异模型检验 EA 终止对食物不足的影响。额外的分析使用差分差异分析的 Callaway-Sant'Anna 方法检验了这种关联。
使用 TWFE,EA 终止与总体样本中食物不足的增加显著相关,也与非西班牙裔白人、西班牙裔、年收入低于 25000 美元的个体相关。对 EA 终止与食物不足的时变关联的调查表明,在回溯后的第二周,EA 终止与更大的食物不足显著相关。使用 Callaway-Sant'Anna 方法的差异分析表明,各州的 EA 回溯与非西班牙裔白人群体更高的食物不足显著相关。
研究结果表明,在通胀相应飙升的情况下,EA 终止可能导致家庭食物不足率上升。
