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]
Free market In economics, a free market is an idealized system in which the prices for goods and services are determined by the open market and consumers, in which the laws and forces of supply and demand are free from any intervention by a government, price-setting monopoly, or other authority. Proponents of the concept of free market contrast it with a regulated market, in which a government intervenes in supply and demand through various methods such as tariffs used to restrict trade and protect the economy. In an idealized free market economy, prices for goods and services are set freely by the forces of supply and demand and are allowed to reach their point of equilibrium without intervention by government policy.
