Hi there,
I am wondering whether/how, if I use a matching estimator with a
command like -nnmatch-, I can check how the effect of a treatment
varies with age?
In a regression I would interact the treatment dummy with the age
variable, but I'm not sure whether something analogous is possible in
matching.
Or will I then need to not include age as a matching variable, and
instead still run a regression after creation of the matched dataset?
Thanks,
J
