what is a command economy 
a command economy is a key aspect of a political system in which a central governmental authority dictates the levels of production that are permissible and the prices that may be charged for goods and services most industries in command economies are publicly owned the main alternative to a command economy is a free market system in which supply and demand dictate production and prices the command economy is a component of a communist political system while a free market system exists in capitalist societies understanding command economycuba north korea and the former soviet union all have command economies china maintained a command economy until 1978 when it began its transition to a mixed economy that blends communist and capitalist elements 1 its current system has been described as a socialist market economy the command economy also known as a planned economy requires that a nation s central government own and control the means of production private ownership of land and capital is nonexistent or severely limited central planners set prices control production levels and limit or prohibit competition within the private sector in a pure command economy there is no private sector as the central government owns or controls all business in a command economy government officials set national economic priorities including how and when to generate economic growth how to allocate resources and how to distribute the output this often takes the form of a multi year plan capitalists may argue that command economies face at least two major problems first is the incentive problem and second is an information vacuum among the central planners making all the decisions the incentive problemthe incentive problem starts at the top policymakers even in a command economy are all too human political interest groups and the power struggles between them will dominate policymaking in a command economy even more than in capitalist economies because they are not constrained by market based forms of discipline such as sovereign credit ratings or capital flight wages are set centrally for workers and profits are eliminated as an incentive for management there is no apparent reason to produce excellence improve efficiency control costs or contribute effort beyond the minimum required to avoid official sanction getting ahead in a command economy requires pleasing the party bosses and having the right connections rather than maximizing shareholder value or meeting consumer demands corruption tends to be pervasive the incentive problem includes the issue known as the tragedy of the commons on a larger scale than is seen in capitalist societies resources that are commonly owned are effectively unowned all of their users or workers lack any incentive to preserve them things such as housing developments factories and machinery wear out break down and fall apart rapidly in a command economy the information vacuumthe problem of economic calculation in a command economy was first described by austrian economists ludwig von mises and f a hayek central planners must somehow calculate how much of every product and service should be produced and delivered 2in a free market system this is determined in a decentralized manner through the interaction of supply and demand consumers shape demand by the products and services they buy or don t buy producers respond by creating more of the products and services that consumers demand moreover all of these factors are quantifiable at every step of the supply chain someone is keeping count of the number of avocados pairs of blue jeans and lug wrenches that are in demand out there in a command economy central planners should at least initially have a grasp on the basic life or death needs of the population in terms of food clothing and shelter but without the forces of supply and demand to guide them they have no rational method to align the production and distribution of goods with consumer wants and preferences over time the incentive and economic calculation problems of a command economy mean that resources and capital goods are wasted and the society is impoverished arguments in favor of command economiesproponents of command economies argue that they allocate resources to maximize social welfare unlike in free market economies where this goal is secondary to maximizing private profit command economies may have better control of employment levels than free market economies they can create jobs to put people to work when necessary even in the absence of a legitimate need lastly command economies are seen as better able to take decisive coordinated action in the face of a national emergency or crisis such as a war or natural disaster although even market based societies may curtail property rights and greatly expand the emergency powers of their central governments during such events at least temporarily
