You've completely lost me here. Care to rephrase?

This is from a rather different discussion, of the suppy side of
investments rather than the demand side you and I've been discussing.
There is a literature where people estimate these sorts of returns,
and I conveyed the results I recall. I'm not up on it enough to
give you much more detail how they got their estimates; you'll
have to go read that stuff yourself to find that out. I do know
enough about those researchers, however, to grant them the benefit
of the doubt.
