You can always supply arbitrary identifiers by
bysort firm : gen newid = _n
and then use -i(firm newid)- in the -reshape- call.
You just have to remember that they are arbitrary.
I can't see where -duplicates drop- would come in here. You don't have
duplicates and even if you did they would be extra information.
