are the any main elements of a command economy?

Answer 1

A planned economy is an economic system in which a single agency makes all decisions about the production and allocation of goods and services. The term is used most often to refer to a centrally-planned economy (or command economy), in which the state or government controls the factors of production and makes all decisions about their use and about the distribution of income.[1] In a centrally-planned economy, the planners decide what should be produced and direct enterprises to produce those goods.[2] A planned economy is usually contrasted with a market economy, where production, distribution, and pricing decisions are made by the private owners of the factors of production and influenced by market forces. A planned economy may either consist of state owned enterprises, private enterprises who are directed by the state, or a combination of both. Though planned economies are usually defined in contrast to market economies, it is not necessary for an economy to be either market-based or centrally-planned; other systems also exist.

Important planned economies that existed in the past include the Economy of the Soviet Union, which was for a time the world's second-largest economy. Beginning in the 1980s and 1990s, many governments presiding over planned economies began deregulating and moving toward market based economies by introducing market forces to determine pricing, distribution, and production. Although most economies today are market economies or mixed economies, planned economies exist in some countries such as Cuba and North Korea.[3]

While the term planned economy usually refers to centrally-planned economies, it may also be used to refer to decentralized systems of planning such as participatory economics

Answer 2

Economy planned and directed by government, where resources are allocated to factories by the state through central planning(refer my source).although there are many upsides in this(that's some thing capitalists wouldn't agree).most of the communist countries have this model.and government subsidies and cooperative systems are part of this economy.
