From Wikipedia: Criticism of socialism.
Distorted or absent price signals
The economic calculation problem is a criticism of central economic planning. It was first proposed in 1854 by the Prussian economist Hermann Heinrich Gossen. It was subsequently expounded in 1902 by the Dutch economist Nicolaas Pierson, in 1920 by Ludwig von Mises, and later by Friedrich Hayek. The problem referred to is that of how to distribute resources rationally in an economy. The free market relies on the price mechanism, wherein people individually have the ability to decide how resources should be distributed based on their willingness to give money for specific goods or services. The price conveys embedded information about the abundance of resources as well as their desirability which in turn allows—on the basis of individual consensual decisions—corrections that prevent shortages and surpluses. Mises and Hayek argued that this is the only possible solution and without the information provided by market prices socialism lacks a method to rationally allocate resources. Those who agree with this criticism argue it is a refutation of socialism and that it shows that a socialist planned economy could never work. The debate raged in the 1920s and 1930s and that specific period of the debate has come to be known by economic historians as “the Socialist Calculation Debate”.
Ludwig von Mises argued in a famous 1930 [actually 1920] article “Economic Calculation in the Socialist Commonwealth” that the pricing systems in socialist economies were necessarily deficient because if government owned the means of production, then no prices could be obtained for capital goods as they were merely internal transfers of goods in a socialist system and not “objects of exchange”, unlike final goods, therefore they were unpriced and hence the system would be necessarily inefficient since the central planners would not know how to allocate the available resources efficiently. This led him to declare “that rational economic activity is impossible in a socialist commonwealth“. Mises developed his critique of socialism more completely in his 1922 book Socialism, an Economic and Sociological Analysis.
Friedrich Hayek argued in 1977 that “prices are an instrument of communication and guidance which embody more information than we directly have” and therefore “the whole idea that you can bring about the same order based on the division of labor by simple direction falls to the ground”. He further argued that “if you need prices, including the prices of labor, to direct people to go where they are needed, you cannot have another distribution except the one from the market principle”.
Ludwig von Mises argued that a socialist system based upon a planned economy would not be able to allocate resources effectively due to the lack of price signals. Because the means of production would be controlled by a single entity, approximating prices for capital goods in a planned economy would be impossible. His argument was that socialism must fail economically because of the economic calculation problem—the impossibility of a socialist government being able to make the economic calculations required to organize a complex economy. Mises projected that without a market economy there would be no functional price system, which he held essential for achieving rational and efficient allocation of capital goods to their most productive uses. According to Mises, socialism would fail as demand cannot be known without prices.
The socialist planner, therefore, is left trying to steer the collectivist economy blindfolded. He cannot know what products to produce, the relative quantities to produce, and the most economically appropriate way to produce them with the resources and labor at his central command. This leads to “planned chaos” or to the “planned anarchy” to which Pravda referred…. Even if we ignore the fact that the rulers of socialist countries have cared very little for the welfare of their own subjects; even if we discount the lack of personal incentives in socialist economies; and even if we disregard the total lack of concern for the consumer under socialism; the basic problem remains the same: the most well-intentioned socialist planner just does not know what to do.
The heart of Mises’ argument against socialism is that central planning by the government destroys the essential tool – competitively formed market prices – by which people in a society make rational economic decisions.
The anarcho-capitalist economist Hans-Hermann Hoppe argues that in the absence of prices for the means of production, there is no cost-accounting which would direct labor and resources to the most valuable uses. Hungarian economist Janos Kornai has written that “the attempt to realize market socialism […] produces an incoherent system, in which there are elements that repel each other: the dominance of public ownership and the operation of the market are not compatible”.
Proponents of laissez-faire capitalism argue that although private monopolies do not have any actual competition, there are many potential competitors watching them and if they were delivering inadequate service, or charging an excessive amount for a good or service, investors would start a competing enterprise.
In her book How We Survived Communism and Even Laughed, Slavenka Drakulić claims that a major contributor to the fall of socialist planned economies in the former Soviet bloc was the failure to produce the basic consumer goods that its people desired. She argues that because of the makeup of the leadership of these regimes, the concerns of women got particularly short shrift. She illustrates this in particular by the system’s failure to produce washing machines. If a state-owned industry is able to keep operating with losses, it may continue operating indefinitely producing things that are not in high consumer demand. If consumer demand is too low to sustain the industry with voluntary payments by consumers, then it is tax-subsidized. This prevents resources (capital and labor) from being applied to satisfying more urgent consumer demands. According to economist Milton Friedman: “The loss part is just as important as the profit part. What distinguishes the private system from a government socialist system is the loss part. If an entrepreneur’s project doesn’t work, he closes it down. If it had been a government project, it would have been expanded, because there is not the discipline of the profit and loss element”.
Pierre-Joseph Proudhon raises similar calculational issues in his General Idea of the Revolution in the 19th Century, but also proposes certain voluntary arrangements, which would also require economic calculation.
Leon Trotsky, a fierce proponent of decentralized economic planning, argued that centralized economic planning would be “insoluble without the daily experience of millions, without their critical review of their own collective experience, without their expression of their needs and demands and could not be carried out within the confines of the official sanctums” and “[e]ven if the Politburo consisted of seven universal geniuses, of seven Marxes, or seven Lenins, it will still be unable, all on its own, with all its creative imagination, to assert command over the economy of 170 million people”.
Mises argued that real-world implementation of free market and socialist principles provided empirical evidence for which economic system leads to greatest success:
The only certain fact about Russian affairs under the Soviet regime with regard to which all people agree is: that the standard of living of the Russian masses is much lower than that of the masses in the country which is universally considered as the paragon of capitalism, the United States of America. If we were to regard the Soviet regime as an experiment, we would have to say that the experiment has clearly demonstrated the superiority of capitalism and the inferiority of socialism.
According to Tibor R. Machan: “Without a market in which allocations can be made in obedience to the law of supply and demand, it is difficult or impossible to funnel resources with respect to actual human preferences and goals”.
