If you ran the analysis in -psmatch2- there is an accompanying program
called -pstest- (findit pstest)

This is the easiest approach since you don't have to rename the variables
needed for the program to run

- -pbalchk- by Mark Lunt "findit" also checks balancing.

Misspecification problems have nothing to do with bootstraping. Bootstraping
is required when the sample is too small and you do not rely on the closed
form for computing the SE of the ATT.
Moreover, as far as I can see from your output the ATT is not significant
and it will not become significant by simply bootstraping.
Finally, beware when using psmatch2 because it does not check for the
balancing to hold, that means that the balancing must be checked by the
Ichino and friend's routine, pscore.
