This study investigates how female employment and family formation trajectories jointly intersect with welfare regimes to shape later life health outcomes. Using a machine learning-based g-computation framework, it estimates the effects of typical employment and family trajectories across Scandinavian, Mediterranean, and Corporatist welfare regimes. The results show that health advantages and disadvantages are shaped less by roles themselves than by the institutional contexts in which women combine and sustain them across the life course.

This study examines how armed conflict influences population size and growth using an agent-based model situated in Nepal during the 1996-2006 armed conflict. Contrary to intuitive expectations, the analysis finds that conflict can increase population size and growth during the conflict period, largely through sharp increases in marriage and marital fertility, with effects that persist long after the violence ends.

This manuscript examines whether the educational attainment polygenic index shapes years of schooling and first-job socioeconomic status directly or primarily through the social mechanisms highlighted in classic status-attainment research. Using Wisconsin Longitudinal Study data and structural equation modeling, it shows that most of the association between EA-PGI and educational attainment is indirect, operating through family background, school rank, aspirations, and encouragement from significant others.
