> Romer's textbook of course gave him total mainstream cred You might be thinking of David Romer's textbook. As far as I know, Paul Romer never wrote one. Paul Romer had tons of mainstream cred from his two classic publications. He left the profession and really didn't have anything to do with it for many years, even becoming a startup founder. Then he showed up to coin the term mathiness while criticizing his advisor, and later wrote a critique of modern macro.
