Pete, I humbly suggest that most economists do use models (of their own design of course) and that has been part of the circular 'proofs' fallacy of the field. I posted the abstract and .pdf of a debunking paper on this yesterday. non-equilibrium economics deals with unknown future wild cards which cannot always be imagined in model design. Plus, as Korzybski said: "the map is not the territory."
