3. You suspect that women may have a different return to work experience and to college education than men, so you estimate the following regression. Note that "Col" and "Fem" are binary variables. Wage=7.10―1.75Fem+2.50Co+0.15Exp+0. 10Fem∗Exp+1.50Fem∗Coa) How much does each additional year of experience add to the hourly wage of a male worker? A female worker? b) Consider a male and a female who have the same level of education. At what level of experience would you predict them to have the same wage? c) Find the expression for the wage gap by taking the derivative of wage with respect to being female. What is the wage gap for a woman with no college degree and 5 years of experience? What is the wage gap for a woman with a college degree and 5 years of experience?
