The proposed paper aims at explaining cross-national differences in gendered care/work regimes of modern post-industrial democracies. As analytical frame a configurational model is proposed that links feminist mobilization to the prevailing structures of the welfare regime and the political decision-making context (i.e. the partisan power configuration and the institutional reform capacity of the government). The core hypothesis is that strong feminist mobilization leads to lower care/work-gender-gaps even in familialist welfare regime settings. This effect is contingent on the joint presence of responsive governments (leftist or liberal) and high reform capacities. Methodologically, the paper combines correlational analysis with configurational methods (QCA) for a sample of advanced post-industrial democracies.
