Feminist research on the welfare state has improved our understanding of th
e nature, origins, and consequences of social policy regimes. Efforts to ev
aluate welfare states through the lens of gender have pinned down how socia
l policy regimes affect men and women differently, usually to the disadvant
age of women. The extent and nature of this disadvantage varies markedly ac
ross OECD countries. Class relations, religion, and political institutions
are three variables that help explain differences in the gender dimensions
of welfare states. While gender should be a factor in any analysis of socia
l policy, this research agenda is weakened by larger unresolved debates amo
ng feminists over what forms of social policy best address the needs and pr
eferences of women.
