A recent study by Prof. Jessica Reyes at Amherst College finds that female gynecologists charge a standard fee for a basic patient visit that is $4.81 (on average) higher than male gynecologists charge. Furthermore, she finds that waiting lists to see female gynecologists are 1.14 weeks longer than waiting lists to see male gynecologists.

• Give two possible explanations for Prof. Reyes's findings. One explanation should focus on the demand side of the market for gynecologists; the other should focus on the supply side.

A further question that I do not understand is: Does the supply curve for a female doc lie to the left or right of a male doc? What should a female doc do to reduce wait times?
