st: Calculating income effects associated with migration using PSMATCH2

[Bruce Newbold <newbold@mcmaster.ca>]

I am using Stata and the psmatch2 command to evaluate the income effects 
of  migration between regions, as in the following command:

. psmatch2 mig_into_to male married a2024 hs2 degree2 ch_deg 
kworker2  newkwork latinc42_2 panel2 panel3 atl que pra bc, out(atincdiff) 
logit com

where mig_into_to is the dependent variable (1/0) that represents 
migrants/stayers in this case. The balance of variables are hypothesized to
related to the migration decision, such as educational degree, marital 
status, origin region, and so on. The out(atincdiff) variable represents
the income effect (difference in after tax income between start and end 
period of the data).  I have also used the pstest command to look at the
pairing effects.

I would like to have Stata calculate the average effect for migrants and 
stayers based on the psmatch2 results (or I guess its mean wage of 
matched  treated / matched controls), but am unsure how to do this.

Suggestions? With thanks.
