[영문]The Food Stamp Program (FSP) and Supplemental Security Income (SSI) are important parts of national public assistance policy, and there is considerable overlap in the populations that the programs serve. This article investigates FSP participation by households that include SSI recipients and assesses the importance of various provisions of the Food Stamp Program that favor SSI recipients. The overlap between the FSP and SSI is significant and that the FSP benefit contributes substantially to the resources of the households of about half of all SSI recipients. The authors argue that measures of FSP take-up by eligible households that include SSI recipients overstate participation and, as a result, may be misleading as a basis for predicting the payoff to renewed agency efforts to raise FSP participation.
