To Grandmother's House We Go: Informal Childcare and Female Labor Mobility
研究了美国女性因育儿需求而返乡迁移的现象，发现靠近父母居住能降低育儿对收入的负面影响，并评估了育儿补贴对女性收入和流动性的提升作用。
ABSTRACT We document how childcare costs and the location of extended family influence the labor supply and mobility of US women. Women return to their home locations immediately before fertility events, suggesting that informal childcare needs may motivate home migration. Women who live near their parents have lower child earnings penalties. We then build a model of labor supply and migration to assess the impacts of childcare subsidies. Childcare subsidies increase earnings and mobility among US women and ignoring migration can understate the welfare benefits of these policies, especially for college‐educated women and those whose parents' locations have poor amenities.
