st: Update to decomp (Blinder-Oaxaca wage decompositions)
Thanks to Kit Baum, the latest version (1.5) of decomp is now on
SSC archives. To update, just type:
ssc install decomp, replace
The latest version has been rewritten for Stata 8.2 (though it
will work under Version 7, see the help file). It now supports
Stata's heckman command and the help file has been expanded.
To summarise the ssc description:
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.
The heck option allows decomp to be used with Stata's heckman command.
