Toward the end of Lange’s classic essay on market socialism, he argues that a socialist government must socialize the means of production “at one stroke” or give up the goals of socialism altogether.
This is not market socialism for the timid!
The Calculation Debate
This essay is Lange’s to answer the “calculation problem” raised by Ludwig von Mises. Mises claimed that without markets, socialist society would not be able to correctly estimate the value of the inputs of the production process. Shortage and poor quality would inevitably follow.
Lange predicts that a future socialist government will erect statues to von Mises for helping to identify and solve this problem of socialism. He attempts to show that a socialist Central Planning Board could set and adjust prices in much the same way as a competitive market — through the successive correction of prices by trial and error until supply and demand meet.
I think Lange’s central insight — that a socialist society must use the price system and supply and demand to maximize the use of its productive resources — is correct.
In order for Lange's plan to work, production managers must make every effort to economize their use of inputs, and use the prices set by the Central Planning Board in all accounting. But Lange does not say how planners would enforce these requirements. There are really only two methods: one is the method of Soviet central planners — impose control and strict accounting from above, however imperfectly. The other is to have a market for capital goods themselves.
Lange is silent on which he would endorse, but he does show that his method could work without an actual market for consumer goods, if the Central Planning Board diligently tracks shortages and over-production and adjusts prices by supply and demand.
I see three difficulties here: one is of course the sheer diversity of production inputs — from different grades of raw materials, to tools and spare parts.
Another difficulty is how to determine when an equilibrium price has been reached. Detecting over-production is easy — there’s too much of a particular product. But how is a Central Planning Board to detect shortage? In the case of shortage, the price (which is too low) would clear the market of the good even though many more producers would be willing to buy it at that price. I think the only way to detect and eliminate a shortage would be to — by trial and error — raise the price of products until a slight surplus appears.
And there is a final difficulty. Without a market for producer goods, producers may be forced to use low-quality inputs even if they would prefer — and pay more for — higher-quality inputs. This was the situation in the Soviet Union, where for example, makers of heavy equipment did not provide installation, maintenance, or spare parts for the machinery they produced. Nove points out that central planning can work best for commodities that are uniform in quality — like water or electricity — or that require national centralization in order to function properly — like national rail networks.
Lange says that the Central Planning Board would allow supply and demand to set the price and production levels of consumer goods. The experience of the USSR shows the pitfalls of not following this practice. There were often multiple prices for consumer goods — an official, lower price, and then the actual price at which they were sold. Officials often lowered the official prices in a bid to win popular support. Chronic shortage was the result.
“At one stroke"
I have often associated market socialism with a gradual transition to socialism. Lange blows that idea to shreds — and for a simple reason: any industry that expects it can or will be next to be socialized will be ruined by its owner long before socialization happens. The experience in Chile, where a revolt of owners and professionals created chaos and set the stage for the coup, certainly bears out his prediction.
Even the Bolsheviks embraced nationalization and socialization months after the October Revolution, once it became clear that capitalists were intent on sabotaging production. Lange says that socialization must be the first step of any socialist government that wants to succeed.
This does not mean everything will be nationalized. Lange prefers to leave production in areas where there are many competing producers — and supply and demand still sets prices — alone. If there are certain sectors — like small agriculture or small tradespeople — that the government intends to leave in private hands, it must say so up front. Otherwise these sectors would be thrown into chaos too.
That does not mean that we should only take power when we have a mass movement behind us that can carry through a thorough socialization of the economy. Lange says that socialists can and should seek to win office on “a labor platform” of taking on capital to restart a depressed economy and protect working people. But when the time is right to embark on socialization, we must not hesitate. Socialist politics “is not for the timid” Lange says.
Conclusion
Lange’s key insight — that a socialist system must use supply and demand to set the price of production inputs — is correct. There may be some instances where this could happen inside a central plan. But I believe that we will have to go further — socialized industries will have to buy their inputs on a market, from other socialized industries, and sell on a market to consumers and other producers. That is the only way — short of a massive, top-down bureaucracy, to enforce accounting rules, maximize our use of scarce resources, and ensure a good life for all.
