Suppose years of schooling, s, is the only variable that affects earnings. The equations for the weekly salaries of male and female workers are given by wm = 500 + 100s and wf = 300 + 75s.
On average, men have 14 years of schooling and women have 12 years of schooling.
(a) What is the male-female wage differential in the labour market?
(b) Calculate how much of this wage differential is due to discrimination and how much is due to difference in skills.
