If a question is off topic because it belongs on another stackexchange, I think it should be easy to vote to migrate it and I can't see how we would do it now except in a comment to a moderator.
In particular, we have many questions come up that should really be in economics.stackexchange.com. According to
there should be a migration path that perhaps can be an option when we vote to close the question. Is this something that can be easily set up? At present they get put on hold, presumably until a mod moves them. Not efficient.
I apologize if there's currently an obvious option to do this and I am not seeing it. I'm basing my belief partly on the frequency with which I find posts on hold because they belong elsewhere.
