For a more academic-economics-oriented article on the same theme by the same authors, see <a href="http://www.utdallas.edu/~liebowit/keys1.html" rel="nofollow">http://www.utdallas.edu/~liebowit/keys1.html</a> , from _Journal of Law and Economics_.<p>Incidentally, I would be very interested in a pointer to a comparably serious/academic rebuttal of Fable of the Keys. It has been a very long time since Fable of the Keys was published, and it has been a long time since I last tuned into the controversy, and at that time my understanding was that a rebuttal had long been promised but never produced.
