Market economy

Modern Market Economies
Every economy in the modern world falls somewhere along a continuum running from pure market to fully planned. Most developed nations are technically mixed economies because they blend free markets with some government interference. However, they are often said to have market economies because they allow market forces to drive the vast majority of activities, typically engaging in government intervention only to the extent it is needed to provide stability.
Market economies may still engage in some government interventions, such as price-fixing, licensing, quotas, and industrial subsidies. Most commonly, market economies feature government production of public goods, often as a government monopoly. But overall, market economies are characterized by decentralized economic decision making by buyers and sellers transacting everyday business. In particular, market economies can be distinguished by having functional markets for corporate control, which allow for the transfer and reorganization of the economic means of production among entrepreneurs.
Although the market economy is clearly the popular system of choice, there is significant debate regarding the amount of government intervention considered optimal for efficient economic operations. Economists mostly believe that more market oriented economies will be rather successful at generating wealth, economic growth, and rising living standards, but often differ on the precise scope, scale, and specific roles for government intervention that are necessarily to provide the fundamental legal and institutional framework that markets might need in order to function well.
A market economy is an economic system in which the decisions regarding investment, production and distribution to the consumers are guided by the price signals created by the forces of supply and demand, where all suppliers and consumers are unimpeded by price controls or restrictions on contract freedom. 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]
Market economies range from minimally regulated free-market and laissez-faire systems where state activity is restricted to providing public goods and services and safeguarding private ownership,^[3] to interventionist forms where the government plays an active role in serving special interests and promoting social welfare. State intervention can happen at the production, distribution, trade and consumption areas in the economy. The distribution of basic need services and goods like health care may be entirely regulated by an egalitarian public health care policy, while at the same time having the production provided by private enterprise, effectively eliminating the forces of supply and demand. These economies are not market economies and display market failure of a market economy for basic needs and anti-competitive practices with respect to individual private customers.
State-directed or dirigist economies are those where the state plays a directive role in guiding the overall development of the market through industrial policies or indicative planning—which guides yet does not substitute the market for economic planning—a form sometimes referred to as a mixed economy.^[4][5]
Market economies are contrasted with planned economies where investment and production decisions are embodied in an integrated economy-wide economic plan. In a centrally planned economy, economic planning is the principal allocation mechanism between firms rather than markets, with the economy's means of production being owned and operated by a single organizational body.^{[6][better source needed]}
