Free market

In economics, a free market is an economic system in which the prices of goods and services are determined by supply and demand expressed by sellers and buyers. Such markets, as modeled, operate without the intervention of government or any other external authority. Proponents of the free market as a normative ideal contrast it with a regulated market, in which a government intervenes in supply and demand by means of various methods such as taxes or regulations. In an idealized free market economy, prices for goods and services are set solely by the bids and offers of the participants.

Scholars contrast the concept of a free market with the concept of a coordinated market in fields of study such as political economy, new institutional economics, economic sociology, and political science. All of these fields emphasize the importance in currently existing market systems of rule-making institutions external to the simple forces of supply and demand which create space for those forces to operate to control productive output and distribution. Although free markets are commonly associated with capitalism in contemporary usage and popular culture, free markets have also been components in some forms of market socialism.

Historically, free market has also been used synonymously with other economic policies. For instance proponents of laissez-faire capitalism may refer to it as free market capitalism because they claim it achieves the most economic freedom. In practice, governments usually intervene to reduce externalities such as greenhouse gas emissions; although they may use markets to do so, such as carbon emission trading.

Capitalism is an economic system based on the private ownership of the means of production and their operation for profit. Central characteristics of capitalism include capital accumulation, competitive markets, a price system, private property and the recognition of property rights, voluntary exchange, and wage labor. In a capitalist market economy, decision-making and investments are determined by every owner of wealth, property or production ability in capital and financial markets whereas prices and the distribution of goods and services are mainly determined by competition in goods and services markets.

Economists, historians, political economists and sociologists have adopted different perspectives in their analyses of capitalism and have recognized various forms of it in practice. These include laissez-faire or free-market capitalism, state capitalism and welfare capitalism. Different forms of capitalism feature varying degrees of free markets, public ownership, obstacles to free competition and state-sanctioned social policies. The degree of competition in markets and the role of intervention and regulation as well as the scope of state ownership vary across different models of capitalism. The extent to which different markets are free and the rules defining private property are matters of politics and policy. Most of the existing capitalist economies are mixed economies that combine elements of free markets with state intervention and in some cases economic planning.

Market economies have existed under many forms of government and in many different times, places and cultures. Modern capitalist societies—marked by a universalization of money-based social relations, a consistently large and system-wide class of workers who must work for wages (the proletariat) and a capitalist class which owns the means of production—developed in Western Europe in a process that led to the Industrial Revolution. Capitalist systems with varying degrees of direct government intervention have since become dominant in the Western world and continue to spread. Capitalism has been shown to be strongly correlated with economic growth.

For classical economists such as Adam Smith, the term free market refers to a market free from all forms of economic privilege, monopolies and artificial scarcities. They say this implies that economic rents, which they describe as profits generated from a lack of perfect competition, must be reduced or eliminated as much as possible through free competition.

Economic theory suggests the returns to land and other natural resources are economic rents that cannot be reduced in such a way because of their perfect inelastic supply. Some economic thinkers emphasize the need to share those rents as an essential requirement for a well functioning market. It is suggested this would both eliminate the need for regular taxes that have a negative effect on trade (see deadweight loss) as well as release land and resources that are speculated upon or monopolised, two features that improve the competition and free market mechanisms. Winston Churchill supported this view by the following statement: "Land is the mother of all monopoly". The American economist and social philosopher Henry George, the most famous proponent of this thesis, wanted to accomplish this through a high land value tax that replaces all other taxes. Followers of his ideas are often called Georgists or geoists and geolibertarians.
