Household skills and low wages
研究发现，当工作与家务技能相似时，从事这类工作的个人会接受低于传统人力资本理论预测的工资，而家庭技能较低的人更倾向于接受高等教育。
Household skills provide job skills when tasks in jobs and household production are similar and jobs produce substitutes for home-made services. Opportunity costs of higher education are foregone earnings during schooling and foregone household production while studying and later in life. I show that individuals in jobs requiring household skills accept lower wage rates than traditional human capital theory predicts, and that individuals with low household skills tend to enter higher education. According to these results, declining household skills may have contributed to the observed increasing demand for higher education by women.
