| That argument, commonly associated with Hayek, quite trivially does not make sense. If the information is unknowable, then it cannot play any role economically. If it is unknowable, the market itself cannot act upon it either. The idea lurking here is of inarticulable knowledge or inexpressible information -- and it is a contradiction in terms. Hayek's big point -- in 'The Use of Knowledge in Society' -- is really this: an economic system is a cooperative system, a cooperative system requires networking/sharing information, and money and markets are a way to convey and share information. Hayek does not prove that centralisation is impossible, nor does he prove that money and markets are the only means to run an economy. An argument based on information is not going to get you there -- rather the opposite in fact. Later in that article, Hayek says -- about gathering dispersed knowledge etc. -- (not) "likely" rather than "never", and also says "it is just conceptually possible". That is the sensible view: if the market is performing a computation, then any sufficiently powerful general computer could emulate it and any sufficiently good network could transmit the relevant information around. Indeed, with enough power you could process more information than the money-market system. And that is actually where we are now. When there is a pocketable networked computer for every human on the planet, that rather blows away the idea that we need money to solve the 'economic calculation' problem. The money-market system is already obsolete, it will just take some time to evolve away from it. |
