Résumé
*Health shocks generate consequences that extend beyond affected individuals to their families. This paper examines how parental cancer diagnosis affects family formation decisions among adult children in the Netherlands. Using administrative data and an event-study design, we estimate effects on fertility and couple formation for individuals aged 26 to 35 at the time of the parental shock. Results show that parental cancer diagnosis reduces fertility primarily among individuals already in partnerships at the time of shock. In contrast, we find no effects on partnership formation or marriage timing. These findings suggest that even in institutional contexts with comprehensive social insurance, parental health shocks can alter adult children's family formation trajectories, with implications for demographic patterns in aging societies.
**This paper investigates how addictive behaviors are shaped by social network structures. It analyzes the consumption dynamics of four addictive products (tobacco, alcohol, cannabis, and cocaine) and social network formation. The aim is to identify which network measures best predict future addictive consumption.
I use a stochastic actor-based model to disentangle two effects. First, how network dynamics influence addiction. Second, how addictive behavior influences network dynamics. This allows me to identify network measures that are not biased by addictive consumption. Then, I use these measures to assess their effect on addictive consumption.
