Distorted or absent price signals chart: political intervention in the creation of prices on a
free market through
supply and demand leads to a deviation from the
equilibrium price, according to socialism's critics, causing a multitude of undesirable side effects. The
economic calculation problem is a criticism of
central economic planning which exists in some forms of socialism. 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 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 (
supply and demand) 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". Mises argued in a famous 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. 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. These arguments were elaborated by subsequent Austrian economists such as Hayek Hungarian economist
János 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. 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. According to
Tibor Machan, "[w]ithout 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". 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". Proponents of
chaos theory argue that it is impossible to make accurate long-term predictions for highly complex systems such as an economy.
Pierre-Joseph Proudhon raises similar calculational issues in his
General Idea of the Revolution in the 19th Century, but he 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". In contrast to the lack of a marketplace,
market socialism can be viewed as an alternative to the traditional socialist model. Theoretically, the fundamental difference between a traditional socialist economy and a market socialist economy is the existence of a market for the means of production and capital goods. Socialist
market abolitionists reply that while advocates of capitalism and the Austrian School in particular recognize
equilibrium prices do not exist, they nonetheless claim that these prices can be used as a rational basis when this is not the case, hence markets are not efficient. According to market abolitionists socialists, decentralized planning allows for a spontaneously self-regulating system of stock control (relying solely on
calculation in kind) to come about and that in turn decisively overcomes the objections raised by the economic calculation argument that any large scale economy must necessarily resort to a system of market prices.
Suppression of economic democracy and self-management Central planning is also criticized by elements of the radical left. Libertarian socialist economist
Robin Hahnel notes that even if central planning overcame its inherent inhibitions of incentives and innovation, it would nevertheless be unable to maximize economic democracy and self-management, which he believes are concepts that are more intellectually coherent, consistent and just than mainstream notions of economic freedom. As Hahnel explains: "Combined with a more democratic political system, and redone to closer approximate a best-case version, centrally planned economies no doubt would have performed better. But they could never have delivered economic self-management, they would always have been slow to innovate as apathy and frustration took their inevitable toll, and they would always have been susceptible to growing inequities and inefficiencies as the effects of differential economic power grew. Under central planning neither planners, managers, nor workers had incentives to promote the social economic interest. Nor did impending markets for final goods to the planning system enfranchise consumers in meaningful ways. But central planning would have been incompatible with economic democracy even if it had overcome its information and incentive liabilities. And the truth is that it survived as long as it did only because it was propped up by unprecedented totalitarian political power". == Critique of public enterprise ==
