st: Outcome effect calculation with Propensity Score matching

[Bruce Newbold <newbold@mcmaster.ca>]

I am using 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.
