Low-Skilled Immigration and Parenting Investments of College-Educated Mothers in the United States: Evidence from Time-Use Data
利用美国时间日记调查数据，发现低技能移民通过降低商业育儿成本，显著减少了大学学历母亲对非学龄儿童的基本照料时间，但未减少教育娱乐活动时间。
This paper uses several decades of U.S. time-diary surveys to assess the impact of low-skilled immigration, through lower prices for commercial childcare, on parental time investments. Using an instrumental variables approach that accounts for the endogenous location of immigrants, we find that low-skilled immigration to the United States has contributed to substantial reductions in the time allocated to basic childcare by college-educated mothers of nonschool-aged children. However, these mothers have not reduced the time allocated to more stimulating educational and recreational activities with their children. Understanding the factors driving parental-time investments on children is crucial from a child-development perspective.
