If families strongly prefer male tutors, the difference in male and female tutor wages will eventually disappear due to increased demand for male tutors.
In this scenario:
a. The difference in male and female tutor wages will eventually disappear
If families strongly prefer their children to be tutored by male tutors, the demand for male tutors would increase. As a result, the biased tutoring centers that only hire male tutors would face a higher demand for their services. This increased demand would drive up the wages for male tutors.
As the wages for male tutors rise, it becomes more costly for the biased tutoring centers to hire only male tutors. Eventually, this higher cost would incentivize these centers to consider hiring female tutors as well, aiming to reduce their overall labor costs.
Thus, over time, the increased demand for male tutors and the associated rise in wages would lead biased tutoring centers to reconsider their hiring practices, aiming to level out the difference in wages between male and female tutors.
