one simple possibility is to switch 0s to 1s and 1s to 0s. if that really
won't work for you, then you could match with (a lot of) replacement.

Hi everyone,
Is there a paper that talks about matching when the sample has more
treatment observations than control observations? Is there an algorithm
that works better for this case? Can somebody explain to me why optimal
matching does not work at all in this case?
Thanks,
Ignacio
