This study uses data from the Survey of Income and Program Participation (SIPP) to address these research gaps by analyzing the dynamics of participation and recidivism for two key components of the income maintenance system -- the Aid to Families with Dependent Children (AFDC) and Food Stamp (FSP) Programs. Specifically, we examine the factors associated with moves between participation in a single program and participation in both programs, as well as moves between program participation and periods of self-sufficiency.
