who is primarily responsible for making economic decisions in a market economy
Market economy A market economy is an economic system in which the decisions regarding investment, production, and distribution are guided by the price signals created by the forces of supply and demand. The major characteristic of a market economy is the existence of factor markets that play a dominant role in the allocation of capital and the factors of production.[1][2]
Planned economy Planned economies are held in contrast with command economies, where a planned economy is "an economic system in which the government controls and regulates production, distribution, prices, etc."[11] but a command economy, while also having this type of regulation, necessarily has substantial public ownership of industry.[12] Therefore, command economies are planned economies, but not necessarily the reverse.
