Use MROZ.RAW for this exercise.
(i) Reestimate the labor supply function in Example, using log(Zzours) as the dependent variable. Compare the estimated elasticity (which is now constant) to the estimate obtained from equation at the average hours worked.
(ii) In the labor supply equation from part (i), allow educ to be endogenous because of omitted ability. Use motheduc and fatheduc as IVs for educ. Remember, you now have two endogenous variables in the equation.
(iii) Test the overidentifying restrictions in the 2SLS estimation from part (ii). Do the IVs pass the test
