Text 15. MARKET ECONOMY

The notion of a "free market" where all economic decisions regarding transfers of money, goods, and services take place on a voluntary basis, free of coercive influence, is commonly considered to be an essential characteristic of capitalism. Some individuals contend, that in systems where individuals are prevented from owning the means of production (including the profits), or coerced to share them, not all economic decisions are free of coercive influence, and, hence, are not free markets. In an ideal free market system none of these economic decisions involve coercion. Instead, they are determined in a decentralized manner by individuals trading, bargaining, cooperating, and competing with each other. In a free market, government may act in a defensivemode to forbid coercion among market participants but does not engage in proactive interventionist coercion. Nevertheless, some authorities claim that capitalism is perfectly compatible with interventionist authoritarian governments, and/or that a free market can exist without capitalism.

A legal system that grants and protects property rights provides property owners the entitlement to sell their property in accordance with their own valuation of that property; if there are no willing buyers at their offered price they have the freedom to retain it. According to standard capitalist theory, as explained by Adam Smith, when individuals make a trade they value what they are purchasing more than they value what they are giving in exchange for a commodity. If this were not the case, then they would not make the trade but retain ownership of the more valuable commodity. This notion underlies the concept of mutually-beneficial trade where it is held that both sides tend to benefit by an exchange.

In regard to pricing of goods and services in a free market, rather than this being ordained by government it is determined by trades that occur as a result of price agreement between buyers and sellers. The prices buyers are willing to pay for a commodity and the prices at which sellers are willing to part with that commodity are directly influenced by supply and demand (as well as the quantity to be traded). In abstract terms, the price is thus defined as the equilibrium point of the demand and the supply curves, which represent the prices at which buyers would buy (and sellers sell) certain quantities of the good in question. A price above the equilibrium point will lead to oversupply (the buyers will buy less goods at that price than the sellers are willing to produce), while a price below the equilibrium will lead to the opposite situation. When the price a buyer is willing to pay coincides with the price a seller is willing to offer, a trade occurs and price is determined.

However, not everyone believes that a free or even a relatively-free market is a good thing. One reason proffered by many to justify economic intervention by government into what would otherwise be a free market is market failure. A market failure is a case in which a market fails to efficiently provide or allocate goods and services (for example, a failure to allocate goods in ways some see as socially or morally preferable). Some believe that the lack of " perfect information " or " perfect competition " in a free market is grounds for government intervention. Other situations or activities often perceived as problems with a free market may appear, such monopolies, monopsonies, information inequalities (e.g. insider trading), or price gouging. Wages determined by a free market mechanism are also commonly seen as a problem by those who would claim that some wages are unjustifiably low or unjustifiably high. Another critique is that free markets usually fail to deal with the problem of externalities, where an action by an agent positively or negatively affects another agent without any compensation taking place. The most widely known externality is pollution. More generally, the free market allocation of resources in areas such as health care, unemployment, wealth inequality, and education are considered market failures by some. Also, governments overseeing economies typically labeled as capitalist have been known to set mandatory price floors or price ceilings at times, thereby interfering with the free market mechanism. This usually occurred either in times of crises, or was related to goods and services which were viewed as strategically important. Electricity, for example, is a good that was or is subject to price ceilings in many countries. Many eminent economists have analyzed market failures, and see governments as having a legitimate role to mitigate these failures, for examples through regulation and compensation schemes.

However, some economists, such as Nobel prize-winning economist Milton Friedman as well as those of the Austrian School, oppose intervention into free markets. They argue that government should limit its involvement in economies to protecting freedom rather than diminishing it for the sake of remedying "market failure." These economists believe that government intervention creates more problems than it is supposed to solve. Laissez-faire advocates do not oppose monopolies unless they maintain their existence through coercion to prevent competition, and often assert that monopolies have historically only developed because of government intervention rather than due to a lack of intervention. They may argue that minimum wage laws cause unnecessary unemployment, that laws against insider trading reduce market efficiency and transparency, or that government-enforced price-ceilings cause shortages.
