----------------- HES POSTING ----------------- I discussed this topic in the relevant chapters of my _History of Modern Economic Analysis_ (1985), and provide a short bibliography. If anyone wants to look it up, its on the web at web.bham.ac.uk/r.e.backhouse/hmea. I came to much the same conclusions as those expressed so far on the list.
