The Impact of Welfare Benefits on Single Motherhood and Headship of Young Women: Evidence from the Census
利用1970、1980和1990年人口普查数据，研究美国都市统计区福利补助水平对年轻女性成为单亲母亲或户主的影响，发现对白人和黑人单亲母亲无影响，仅对黑人户主身份有正向作用。
This paper uses data from the 1970, 1980 and 1990 Censuses to investigate the impact of welfare benefits across Metropolitan Statistical Areas (MSAs) on the incidence of single motherhood and headship for young women. A contribution of the paper is the inclusion of both MSA fixed effects and MSA-specific time trends to account for fixed and trending unmeasured factors that could influence both welfare benefit levels and family formation. In such a model, we find no effect of welfare benefits on single motherhood for whites or blacks, and a positive effect of welfare benefits on single headship only for blacks.
