Re: st: repeated time unbalanced panel data

[Daniel Lawson <dlawson1@nd.edu>]

Dear Paulo,

I don't find any specific questions in your e-mail, so I don't know  
what you want help with.  You do state that the sort command doesn't  
seem to be having the effect you want.  It appears to me that the data  
you present are already sorted by id and year.  What other effect would  
you want the sort command to have?

What is the variable ``son06'' ?  Do you have a variable for gender?   
If not, how do you plan to perform Oaxaca decomposition on gender?  If  
age2 is supposed to be the square of age, it is coded wrong.

Perhaps the ``decomp'' command might be helpful to you.  When I typed  
``findit Oaxaca'' into Stata, the command came up.

package decomp from http://fmwww.bc.edu/RePEc/bocode/d

TITLE
      'DECOMP': module to compute decompositions of earnings gaps

DESCRIPTION/AUTHOR(S)

      decomp computes Blinder-Oaxaca wage decompositions. It compares
      the results from two regressions, using intermediate commands
      (himod and lomod), and produces a  table of output containing the
      decompositions. These decompositions show how much of  the wage
      gap is due to differing endowments between the two groups, and
      how much is due to discrimination (regarded as the portion of the
      wage gap due to the combined effect of  coefficients and slope
      intercepts for the two groups). decomp is designed for  Stata's
      regress command, but also works with other regression commands,
      such as ivreg.  heck option allows decomp to be used with Stata's
      heckman command.
