Combined Difference in Difference

[Hossein Kavand]

Hello,
I was wondering if there is any recently developed, ora new command in Stata for Combined Difference in Difference approach that is the combination of matching and DiD.
If there is not, is there any suggestion for doing CDiD in a straightforward way in Stata?

Thanks for your help.

I have not seen any CDiD command in Stata.
Perhaps you might want to take a look at this article (from page 77) and this presentation.
