I think they do. Try “The Great Crash” by Galbraith. He mentions how it is better to be wrong using the “correct methods” than being right using the “wrong” methods. BTW, there was a Harvard society which got everything completely wrong during the 1929 crash and dissolved later. Galbraith talks about this. As Galbraith wryly observes “Economics is very useful – as a source of employment for economists”. I’ll have to agree with Fleckensteins comments forwarded by Powayseller on forecasts by economists.
