摘要 关于减少劳动供给的长期财务成本的信息是否会提高母亲的工作时长？我们以描述性证据表明，母亲在决定其就业水平时，长期财务因素并非首要考虑。此外，相当大比例的女性对兼职工作下的养老金领取和工资增长持有过于乐观的预期。在瑞士开展的一项大规模实地实验中，我们将兼职担任教师的母亲随机分配至接受关于减少劳动供给的长期成本的客观信息的处理组。该处理既提高了对财务信息的需求，也提升了未来的劳动供给计划，尤其是在低估兼职工作成本的女性中。利用干预一年后关联的雇主行政数据，我们发现这一母亲群体将工作时长提高了 7%。这些发现凸显出，减少劳动供给决策中信息摩擦的政策可能有助于缩小劳动力市场中仍然存在的性别差距。
Abstract
Abstract Does information about the long-run financial costs of reduced labor supply increase mothers’ working hours? We document descriptively that long-term financial factors are not top of mind when mothers decide on their employment level. Moreover, a substantial share of women holds overly optimistic expectations about pension receipt and wage growth under part-time work. In a large-scale field experiment in Switzerland, we randomly assign mothers working part-time as teachers to receive objective information about the long-run costs of reduced labor supply. The treatment increases both demand for financial information and future labor supply plans, in particular among women who underestimate the costs of part-time work. Leveraging linked employer administrative data one year post-intervention, we find that this group of mothers increases working hours by 7%. These findings underscore that policies reducing information frictions in labor supply decisions may help address remaining gender gaps in the labor market.
