will the OLS estimation of the population wage equation
Log(W age) = a + B2 Educ + B3 Exper + B4IQ + u , tend to yield biased estimates ?
O Excluding High wage individuals from your sample
Education and IQ are correlated with each other
Including in the regression an additional gender dummy even though you are not sure whether gender
affects log(wage) or not.
O The data have some (randomly) missing values on IQ
