(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?

(i)
Re-estimating the labor supply function using
as the dependent variable and 
as the independent variable such that 
are the set of instrument variables, the result is:
The estimated elasticity of 
with respect to 
is 1.994349
When the labor supply function is estimated using 
as the dependent variable and 
as the independent variable such that 
are the set of instrument variables, the result is:
The coefficient of 
is 1639.56
The estimated elasticity of 
with respect to 
is given by:
Hence, it implies that at the average value of 
which is 1303, the estimated elasticity of 
with respect to 
is:
Hence, the estimated elasticity of 
with respect to 
is 1.994349 of the model in which
is the dependent variable, which is higher than 1.26 of the model in which 
is the dependent variable
