The example you listed above is actually readily solvable through central planning. Basically production possibility curves are drawn up and then the efficient point is found by solving the relevant simultaneous equations. Furthermore market socialism DOES concede the use of money to determine prices for goods so the ratio to which one consumer good is preferred to another is known. For precisely these reasons it was at first considered that Lange won the calculation debate. If the market really is just one big equation solving device, then it would be quite easy for a super computer to do exactly that.
It was actually the work of Kirzner and his insights into the market process as described by Hayek and Mises that put a temporary end to the debate. He declared that even if the socialist economy can allocate capital goods along these lines, it can’t facilitate the discovery process of entrepreneurship.
However, as this article (and do read that article) points out even the market process can be emulated by a central list of non-consumer prices published every second in order to bring markets toward equilibrium by reducing surplus and shortages. This of course allows market socialism to use a single unit of account in a very similar manner to how a capitalist market does.
Now there are two ways of viewing that a) you can see it as “groping in the dark” but then you’d have to concede that entrepreneurs do the same or b) you can see that while the socialist economy can lets say produce a certain set of previously produced goods efficiently it can’t decide where a new factory should be opened or what kind of new product should be made or how many resources should go into making it in the same way a market does.
I think unless the socialism debate is to hit a brick wall, it needs to delve deeper into this “decision” aspect. Simply claiming that the socialist planner cannot add up apples and oranges because he cannot use a single unit of account is not true, it is also not true that he can’t account for trade-offs. He very much so and very easily can.
Where the debate can be won on the side of capitalism is in looking at decisions and recognizing that part of the information contained within a price is unrestricted decision. The capitalist entrepreneur bids up prices because of his personal anticipation of the future, he decides how these resources are to be employed with no restrictions. This is impossible if he is just an overseer of a given production process.
In the capitalist economy the price reflects the opportunity cost of the last entrepreneur’s anticipation of the future, and his appraisal of the good in question. In market socialism the price embodies the opportunity cost of the forgone yield of another already existing production process.
It is this key difference, that might be able to finally win the calculation debate in my mind. However I am not sure how.
The socialist could say that in socialism there might be a group devoted to market research which acts like the entrepreneur in coming up with a new product and then the socialist planners could divert resources in order to produce this new good. Where how and why can be calculated the same way as in a market by comparing expected costs in money price to expected revenues in money terms.
I personally do not yet know how to respond to this. To me the socialist debate is far from over. It is obvious that practically it is almost nigh impossible for socialism to ever work. However I can see how a socialist system can solve some of the problems attributed to it. Maybe I am not yet proficient enough in my readings of Hayek or Mises. I would appreciate any thoughts on some of the issues I have raised
