Needs or obligations? The influence of childcare infrastructure and support norms on grandparents' labour market participation

This study investigates how institutional and normative characteristics affect grandparents' labour market participation. Previous studies indicate that providing regular grandchild care reduces labour market participation, and this linkage varies between European welfare states. Yet the underlying mechanisms remain unclear, and no study has systematically disentangled cultural from institutional influence when investigating grandparents' work-care reconciliation. Based on two mechanisms, needs and obligations, we investigate how (grandparental) support norms and childcare infrastructure jointly shape the labour market participation of active grandparents. We use six waves from the Survey of Health, Aging and Retirement in Europe (SHARE), investigating variation across 91 subnational regions in 18 countries. The results indicate that the regular provision of grandchild care increases the risk of exiting the labour market for both men and women. This linkage is stronger in contexts with stronger support norms, but also depends on the childcare infrastructure in contexts where norms are weaker.
