What informs their human capital?
Even though Eileen and Becky were born in the same country, attended the same university, and studied in the same graduate program, there might be differences in their human capital that settles the wage disparity.
Human capital includes factors like skills, knowledge, work experience, and any additional qualifications. Eileen, being a recent law school graduate, may possess specific skills, achievements, or experiences that set her apart from Becky, justifying a higher starting salary. This difference in human capital is likely the primary reason for the wage gap in this scenario.
