Question 20 One of your classmates suggests that you run the following specification: wage=B+Bimale + Basouth+Bawhite + Bieduc +8s female educ+ Benorth educ + Binonwhite educ + p 3 pts Note that for every individual it must always hold that male + female 1, north + south 1, and white + nonwhite - 1. Can you run this specification? No, because the model is not linear. O No, because it has a problem of perfect multicollinearity. No, because the independent variables are correlated with the error term. Yes, we can run this specification.
