Abstract:
The Supplemental Nutrition Assistance Program (SNAP) plays a key role in the US food system. As Congress considers major changes to it under the 2025 One Big Beautiful Bill Act and states propose restrictions on what benefits may be used to purchase food, SNAP sits at the intersection of food security, labour market policy and public health. Drawing on historical experience and empirical economic evidence, we assess the impact of the proposed changes on SNAP, showing that specific policy solutions could improve outcomes without increasing programme costs, while simplified enrolment procedures could increase programme participation and reduce food insecurity.
