 Although computers cannot solve the problem, Hayek thought radically dispersed decision making by buyers and sellers can and does solve the problem, so far as it can be solved. Sellers who charge too much end up without customers; they learn to be more efficient or else find some other line of work.  [4]  Buyers who want x but consider it overpriced stay home for a while, waiting for the price to fall, but when they see x flying off the shelves, some of them learn something about themselves: that they would rather have the product at that price than not have it at all. To Hayek, only a price mechanism can process changing information almost instantaneously. Ironically, the most efficient thing a central planner could possibly do would be to set a price right where it would have been without the planner’s intervention.
