The Gender Pay Gap Beyond Human Capital
研究发现，除了人力资本，非认知技能（如自信和果断）以及家庭、职业偏好能解释82%的性别薪酬差距，其中人力资本变量占一半，非认知技能和偏好占四分之一。
Focused on human capital, economists typically explain about half of the gender earnings gap. For a national sample of MBAs, we account for 82 percent of the gap by incorporating noncognitive skills (for example, confidence and assertiveness) and preferences regarding family, career, and jobs. Those two sources of gender heterogeneity account for a quarter of the “explained” pay gap, with half due to human capital variables and the other quarter due to hours worked and current job characteristics. Female MBAs appear to pay a penalty for “good citizen” behavior (choosing jobs that contribute to society) and characteristics (higher ethical standards).
