context_page_description: In economics, a free market is a system in which the prices for goods and services are self-regulated by the open market and by consumers. In a free market, the laws and forces of supply and demand are free from any intervention by a government or other authority, and from all forms of economic privilege, monopolies and artificial scarcities. 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 to protect the local 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.
  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.
context_section_description: With varying degrees of mathematical rigor over time, the general equilibrium theory has demonstrated that under certain conditions of competition the law of supply and demand predominates in this ideal free and competitive market, influencing prices toward an equilibrium that balances the demands for the products against the supplies. At these equilibrium prices, the market distributes the products to the purchasers according to each purchaser's preference or utility for each product and within the relative limits of each buyer's purchasing power. This result is described as market efficiency, or more specifically a Pareto optimum.
  This equilibrating behavior of free markets requires certain assumptions about their agents—collectively known as perfect competition—which therefore cannot be results of the market that they create. Among these assumptions are several which are impossible to fully achieve in a real market, such as complete information, interchangeable goods and services and lack of market power. The question then is what approximations of these conditions guarantee approximations of market efficiency and which failures in competition generate overall market failures. Several Nobel Prizes in Economics have been awarded for analyses of market failures due to asymmetric information.
