Work Effort and Work Requirements for Food Assistance among U.S. Adults
研究美国补充营养援助计划（SNAP）的工作要求对低教育低收入成年人工作努力的影响，发现年龄超过50岁后脱离工作要求会减少就业和工作时间，但整体影响有限。
We investigate the effect of Supplemental Nutrition Assistance Program (SNAP) work requirements on work effort for a particularly disadvantaged subgroup of potential SNAP participants. Individuals age out of SNAP work requirements at age fifty and requirements are occasionally waived in certain areas. We leverage this policy variation in a regression discontinuity research design and find that, for adults with low income and low education, aging out of work requirements decreases employment, hours worked, and the probability of working over twenty hours per week only when requirements are in effect. This drop in work effort is not apparent among low‐income adults in general and is driven by individuals leaving the labor force because they report being unable to work or because they retire. The drop is smaller when states do not provide qualifying work opportunities. Overall, although we find meaningful effects consistent with theory for a subset of low‐income adults, it is not clear that the overall number affected is sufficiently large to translate to noticeable labor market effects among low‐income adults without dependents in general.
