Childcare and Long-Term Care: A Tale of Altruism and Strategic Motives within the Family
with Chao Fu and Chamna Yoon
Abstract: We develop and estimate a dynamic model that captures the interactions between grandparents' provision of childcare and their daughters' caregiving for the elderly over the life cycle. Our model accounts for both altruistic and strategic motives underlying the intergenerational time transfers, which we disentangle using data from multiple sources. We use the estimated model to examine the welfare implications of childcare and long-term care policies.
