For example, the (repeated) theorem on full employment ignores the fact that there must be some unemployment in order to allow people to shift jobs. Full employment is thermodynamically analogous to absolute zero, or to the band-level population of electrons in a perfect insulator. You can't get there from here. Other analyses ignore the effects of phase-shifted feedback, which can lead to oscillations (and even chaotic behaviour) under conditions in which the equilibrium solutions are stable. Time matters. Information matters, and most of the analyses require the underlying assumption that the individual performers (workers, capitalists, unemployed ...) have full knowledge of what might happen as a consequence of their individual decisions. When someone suggested that each individual farmer might not be totally aware of the effect of price changes (in reference to the cobweb effect), this suggestion was roundly denounced as slighting the intelligence of farmers. But it was really an assertion that it takes an infinite amount of time to gather all information, and by the time you have gathered it, the situation is different anyway. The analyses put forward by DKMcK are fun to read, but I seldom feel they have much to do with the real world, or even with a contrived world that contains real people and real information systems. -- Martin Taylor {allegra,linus,ihnp4,floyd,ubc-vision}!utzoo!dciem!mmt {uw-beaver,qucis,watmath}!utcsri!dciem!mmt
