Different forms of economic planning have been featured in various models of socialism. These range from decentralized-planning systems which are based on collective decision-making and disaggregated information to centralized systems of planning conducted by technical experts who use aggregated information to formulate plans of production. In a fully developed socialist economy, engineers and technical specialists, overseen or appointed in a democratic manner, would coordinate the economy in terms of physical units without any need or use for financial-based calculation. The economy of the Soviet Union never reached this stage of development, so planned its economy in financial terms throughout the duration of its existence. Nonetheless, a number of alternative metrics were developed for assessing the performance of non-financial economies in terms of physical output (i.e.
net material product versus
gross domestic product). In general, the various models of socialist economic planning such as a
socialist mode of production exist as theoretical constructs that have not been implemented fully by any economy, partially because they depend on vast changes on a global scale. In the context of mainstream economics and the field of
comparative economic systems, socialist planning usually refers to the
Soviet-style command economy, regardless of whether or not this economic system actually constituted a type of
socialism or
state capitalism or a third, non-socialist and non-capitalist type of system. In some models of socialism, economic planning completely substitutes the market mechanism, supposedly rendering monetary relations and the price system obsolete. In other models, planning is utilized as a complement to markets.
Concept of socialist planning The classical conception of socialist economic planning held by
Marxists involved an economic system where goods and services were valued, demanded and produced directly for their
use-value as opposed to being produced as a by-product of the pursuit of profit by business enterprises. This idea of
production for use is a fundamental aspect of a socialist economy. This involves social control over the allocation of the
surplus product and in its most extensive theoretical form
calculation-in-kind in place of financial calculation. For Marxists in particular, planning entails control of the surplus product (profit) by the associated producers in a
democratic manner. This differs from planning within the framework of capitalism which is based on the planned
accumulation of capital in order to either stabilize the business cycle (when undertaken by governments) or to maximize profits (when undertaken by firms) as opposed to the socialist concept of planned production for use. In such a socialist society based on economic planning, the primary function of the state apparatus changes from one of political rule over people (via the creation and enforcement of laws) into a technical administration of production, distribution and organization; that is, the state would become a coordinating economic entity rather than a mechanism of political and class-based control and thereby ceasing to be a state in the Marxist sense. " In the May 1949 issue of the
Monthly Review titled "
Why Socialism?",
Albert Einstein wrote: I am convinced there is only one way to eliminate (the) grave evils (of capitalism), namely through the establishment of a socialist economy, accompanied by an educational system which would be oriented toward social goals. In such an economy, the means of production are owned by society itself and are utilized in a planned fashion. A planned economy, which adjusts production to the needs of the community, would distribute the work to be done among all those able to work and would guarantee a livelihood to every man, woman, and child. The education of the individual, in addition to promoting his own innate abilities, would attempt to develop in him a sense of responsibility for his fellow-men in place of the glorification of power and success in our present society.
Administrative-command system The concept of a
command economy is differentiated from the concepts of a
planned economy and economic planning, especially by socialists and Marxists who liken command economies (such as that of the former Soviet Union) to that of a single capitalist firm, organized in a top-down administrative fashion based on bureaucratic organization akin to that of a capitalist corporation. Economic analysts have argued that the
economy of the Soviet Union actually represented an administrative or command economy as opposed to a planned economy because planning did not play an operational role in the allocation of resources among productive units in the economy since in actuality the main allocation mechanism was a system of command-and-control. The term
administrative-command economy gained currency as a more accurate descriptor of Soviet-type economies.
Decentralized planning Decentralized economic planning is a planning process that starts at the user-level in a bottom-up flow of information. Decentralized planning often appears as a complement to the idea of
socialist self-management, most notably by
democratic socialists and
libertarian socialists. The theoretical postulates for models of decentralized socialist planning stem from the thought of
Karl Kautsky,
Rosa Luxemburg,
Nikolai Bukharin and
Oskar R. Lange. This model involves economic decision-making based on self-governance from the bottom-up (by employees and consumers) without any directing central authority. This often contrasts with the doctrine of orthodox
Marxism–Leninism which advocates directive administrative planning where directives are passed down from higher authorities (planning agencies) to agents (enterprise managers), who in turn give orders to workers. Two contemporary models of decentralized planning are
participatory economics, developed by the economist
Michael Albert; and negotiated coordination, developed by the economist
Pat Devine.
Lange–Lerner–Taylor model The economic models developed in the 1920s and 1930s by American economists
Fred M. Taylor and
Abba Lerner and by Polish economist
Oskar R. Lange involved a form of planning based on marginal cost pricing. In Lange's model, a central planning board would set prices for producer goods through a trial-and-error method, adjusting until the price matched the marginal cost, with the aim of achieving
Pareto-efficient outcomes. Although these models were often described as
market socialism, they actually represented a form of market simulation planning.
Material balances Material balance planning was the type of economic planning employed by Soviet-type economies. This system emerged in a haphazard manner during the collectivization drive under
Joseph Stalin and emphasized rapid growth and industrialization. Eventually, this method became an established part of the Soviet conception of socialism in the post-war period and other socialist states emulated it in the latter half of the 20th century. Material balancing involves a planning agency taking a survey of available inputs and raw materials and using a balance-sheet to balance them with output targets specified by industry, thereby achieving a balance of supply and demand. In the case of the Soviet Union, this task fell on
Gosplan and its subsidiaries: the industrial ministries and (under
Khrushchev) the regional
sovnarkhozy. The ministries in turn were subdivided into Chief Industrial Administrations (
glavki), under which each enterprise was finally subordinated.
Input-Output Models Input-Output models, developed by
Wassily Leontief, take advantage of
linear programming and
matrices by dividing the economy into interdependent sectors that produce products for both themselves and other sectors; the production in one sector relies in the input of goods from another. The flow of goods strictly between sectors is modelled by a Leontief closed model where the resultant expression takes the form of (I-A)X=0 where X as a variable may represent the optimal payment for each instance of production encoded in the matrix A. More sophisticated methods include open models where production satisfies exterior demand, and generally takes the form X=(I-A)^{-1}D, where D is the demand matrix. This is a modelling method proposed by some socialist economists such as
Paul Cockshott, who argue that the advent of modern computer technology since the times of
Victor Glushkov negates the computational difficulty faced by 20th-century attempts at economic planning (See
OGAS and
Cybersyn). == In capitalism ==
