Trihn,
I have taken advantage of PSMATCH2 from Sianesi and Leuven to identify
the comparison group. You can install it from within STATA using ssc.

Generally I implement a DoD model using regress with the appropriate
fixed effects.

Dear Listers
I'm trying to combine propensity score matching with difference in
differences (as suggested by Blundell and Dias, 2000). I was wondering
if any of you have tried this before and if you would mind sharing
your
Stata code with me?
Thanks
Trinh
