This paper examines how changes in tax policy, welfare programs, public health insurance, and economic conditions during the 1990s affected welfare use and employment among single mothers. Drawing on panel data from the Survey of Income and Program Participation, I give new estimates of the effects of specific policy changes and use those estimates to explain changes in economic behavior. The results suggest that Welfare Reform policies, the EITC, and improved economic conditions, in that order, were the primary determinants of changes in welfare use and employment between 1993 and 1999. | Finance and Economics Discussion Series by Adam Looney, Paperback | Indigo Chapters
