Income and food insecurity among SNAP recipients: a consideration of the SNAP benefit formula
利用2018年调查数据，研究SNAP受助者中食物不安全与总收入及扣除项的关系，发现总收入与食物不安全负相关，扣除项正相关，尤其对有老人或残疾人的家庭影响显著。
Abstract The Supplemental Nutrition Assistance Program (SNAP) has substantially reduced food insecurity in the USA, but almost half of the participants remain food insecure. We use the 2018 Survey of Income and Program Participation to examine the relationship between food insecurity and two components of benefit determination—gross income and deductions. For all SNAP recipients, in most specifications, gross income is inversely related to food insecurity, and deductions are positively correlated with food insecurity. When examining policy-relevant sub-categories, households with a senior or someone with a disability have positive associations between food insecurity and deductions, suggesting possible changes in benefit construction.
