Economic Calculation and the "Impossibility" of Socialism
Mises considered the "socialist calculation argument" to be a decisive objection to the economic feasibility of socialism. There are other valid arguments against socialism; indeed, "No judicious man can fail to conclude from the evidence of these considerations that in the market economy the productivity of labor is incomparable higher than under socialism."[25] However, Mises insists, this does not decide the issue:
If no other objections could be raised to the socialist plans than that socialism will lower the standard of living of all or at least of the immense majority, it would be impossible for praxeology to pronounce a final judgment. Men would have to decide the issue between capitalism and socialism on the ground of judgments of value and of judgments of relevance. They would have to choose between the two systems as they choose between many others things... However, the true state of affairs is entirely different... Socialism is not a realizable system of society's economic organization because it lacks any method of economic calculation... Socialism cannot be realized because it is beyond human power to establish it as a social system.[26]
This conclusion is amazing, for Mises repeatedly insists that economic theory gives only qualitative, not quantitative laws? For example, in Human Action, Mises tells us that:
The impracticality of measurement is not due to the lack of technical methods for the establishment of measure. It is due to the absence of constant relations. If it were only caused by technical insufficiency, at least an approximate estimation would be possible in some cases. But the main fact is that there are no constant relations. Economics is not, as ignorant positivists repeat again and again, backward because it is not "quantitative." It is not quantitative because there are no constants. Statistical figures referring to economic events are historical data. They tell us what happened in a nonrepeatable historical case.[27]
If so, then how could he possibly know by economic theory alone that the negative effect of the lack of economic calculation would be severe enough to make socialism infeasible? Granted, the socialist economy would suffer due to the impossibility of economic calculation; but how, on his own theory, could Mises know that this difficulty to so severe that society would collapse?
The strength of this objection becomes even clearer when we consider the economic decision-making of Robinson Crusoe, alone on his island. As Mises explains, "Isolated man can easily decide whether to extend his hunting or cultivation. The processes of production he has to take into account are relatively short. The expenditure they demand and the product they afford can easily be perceived as a whole."[28] Crusoe's runs his one-man economy simply by using "calculation in kind" - mentally weighing his preferences and opportunities to make decisions. Mises concedes that this situation is conceivable, adding only that this method is unworkable for a larger economy. "To suppose that a socialist community could substitute calculations in kind for calculations in terms of money is an illusion. In an economy that does not practice exchange, calculations in kind can never cover more than consumption goods. They break down completely where goods of higher order are concerned."[29]
This suggests some obvious questions. Does Crusoe's one-man socialism become "impossible" when Friday shows up? Hardly. What if 100 people show up? 1000? Mises' distinction between a modern economy and Crusoe's, and why the economic calculation argument applies only to the former, again shows that Mises has underlying quantitative assumptions in spite of his strictures against them. He is making a quantitative judgment that the lack of calculation would not greatly worsen Crusoe's economy, but would devastate a modern economy. Perhaps Mises was right, but pure economic theory did not give him the answer.
Ever since Mises, Austrians have overused the economic calculation argument. In the absence of detailed empirical evidence showing that this particular problem is the most important one, it is just another argument out of hundreds on the list of arguments against socialism. How do we know that the problem of work effort, or innovation, or the underground economy, or any number of other problems were not more important than the calculation problem?
The collapse of Communism has led Austrians to loudly proclaim that "Mises was right." Yes, he was right that socialism was a terrible economic system - and only the collapse of Communism has shown us how bad it really was. However, current events do nothing to show that economic calculation was the insuperable difficulty of socialist economies. There is no natural experiment of a socialist economy that suffered solely from its lack of economic calculation. Thus, economic history as well as pure economic theory fails to establish that the economic calculation problem was a severe challenge for socialism.[30]
