AFDC and the Formation of Subfamilies
分析AFDC福利对单身母亲是否选择住在子家庭（即寄居在别人家而非独立居住）的影响，发现部分州对子家庭支付较低福利，但影响较小，总体福利水平无显著作用。
This paper analyzes the relationship between AFDC benefits and a single mother's propensity to reside in a subfamily-i.e., within another family rather than in her own independent household. We find that some states pay lower benefits to mothers living in subfamilies. In those states, a single mother may forego a substantial amount of AFDC benefits if she chooses to reside in a subfamily rather than establish her own household. Using data from the 1984 Current Population Survey, we address the question of whether differences in AFDC benefits affect the probability that a mother will reside in a subfamily. We find that the lower benefits paid to subfamilies have discernible but small effects, and that the overall level of AFDC benefits has no effect.
