112 <strong>Prices</strong> <strong>and</strong> <strong>knowledge</strong>Markets <strong>and</strong> decentralized bureaucraciesNelson pointed out once that even though comprehensive centralplanning might be impossible to carry out successfully because ofbounded-rationality considerations, this is not a sufficient argumentfor turning over to <strong>market</strong>s for a solution. There is still anotheralternative to consider: decentralized bureaucracies. In Nelson’swords,[Hayek] argued that…simulated socialist <strong>market</strong>s were likely tooperate much more sluggishly than real capitalist <strong>market</strong>s. Whilehe did not spell out in any detailed way why this should be the case,obviously he did not believe that bureaucratic decentralizationwould be effective. It is apparent that many contemporaryeconomists agree with him.(1977:134)In spite of this apparent agreement among economists, Nelson states,it is not ‘clear that it is impossible to devise responsive decentralizedsystems without going to the unregulated <strong>market</strong>, <strong>and</strong> there may begood reasons for trying’ (ibid.: 141).This is a reasonable argument from a <strong>perspective</strong> emphasizingbounded rationality as the main constraint on a central planner.After all, Simon (1979:501) mentions the division of ‘thedecision-making task among many specialists, coordinating theirwork by means of a structure of communications <strong>and</strong> authorityrelations’ as a procedure already widely used by organizations to‘transform intractable decision problems into tractable ones’. 19 Infact, Simon criticizes the economics literature for treatingorganizations ‘as highly centralized structures in which all theimportant decisions are made at the center’, without noticing that‘real-world organizations behave quite differently’ (1981:48).Although the context of this specific argument suggests thatNelson has in mind decentralized government bureaucracies <strong>and</strong>that he is using the term ‘<strong>market</strong>s’ to include privateorganizations, this is just one instance of the absence, in thebounded-rationality approach, of differentiation between pricemediatedtransacting <strong>and</strong> decentralized organizations.This absence is also noticeable in Simon’s writings. Businessorganizations, Simon believes, ‘like <strong>market</strong> economies, are vast,distributed computers whose final choice <strong>process</strong>es are substantiallydecentralized’ (ibid.: 49; emphasis added).
