Refer to your text MROZ data set (see "Course Resources" in "Modules" -> "Welcome to Class: Your Journey Begins Here!") and use Excel’s regression data analysis tool or Stata to compute the answers to the questions asked. Consider the following model: log(wage) = \beta 0 + \beta 1educ + u (1), where wage is hourly wage and educ is years of schooling. Assume that educ is endogenous (correlated with u). Further assume that motheduc (mother’s education) is uncorrelated with u. Assume that educ and motheduc are correlated. Estimate (1) using motheduc as an IV for educ (using only the working women in the sample). You find that the IV estimate of the return to education is 3.85 %, while the OLS estimate of the return to education is 10.86 %.
