The high and rapidly increasing prevalence of mental illnesses underscores the importance of understanding their causal origins. This paper analyzes one factor at a critical stage of human development: exposure to maternal stress from family ruptures during the fetal period. We find that in...

Social insurance is often linked to marriage. I model how such linkage affects the marriage market, and exploit Sweden’s elimination of survivors insurance to demonstrate economically important responses along several behavioral margins in this market. Entry into marriage reflects a demand for...

This paper examines the long-term impacts of in-utero and early childhood exposure to ambient air pollution on adult labor market outcomes. We take advantage of a new administrative data set that is uniquely suited for addressing this question because it combines information on individuals'...
