Considering Y^M = 40, 000 and Y^F = 28, 000

Considering Y^M = 40, 000 and Y^F = 28, 000, Y^M and Y^F are average earnings for males and females respectively. The following are estimated simple human capital earning functions: ln Y^M = 9.2 + 0.1S^M, S^M = 14; ln Y^F = 9.4 + 0.07SF; S^F = 12; S^M and S^F are average school years for male and female respectively.
