Within economics, a market that runs under laissez-faire policies is a free market. It is “free” within the sense that the federal government makes no attempt to intervene through taxation’s, subsidies, minimum wages, price ceilings, etc. Market prices may be distorted by any seller or vendors with monopoly power, or a customer with monopsony power. Such price distortions might have an adverse effect on market participant’s welfare and reduce the efficiency of market outcomes. Also, the relative amount of organization and settling power of customers and sellers significantly affects the functioning of the market. Markets where cost negotiations meet equilibrium though still do not arrive at preferred outcomes for both sides are believed to experience market disappointment.

Markets are a system, and systems have got structure. System works fine if the structure of a system is in good shape. Structure of any (utopistically) well-functioning markets is defined the theory is that of perfect competitors. Well-functioning markets of the real world are never perfect, but basic structural characteristics could be approximated for real world markets, for example
many small customers and sellers
buyers and vendors have equal use of information
products are equivalent

Buying and promoting in well-structured markets creates an amount that satisfies both buyers and vendors, not buying as well as selling alone as the free market supporters tells us. For example, trade unions are occasionally accused of spoiling the marketplace mechanims of any labour markets, in reality it’s the opposite: blue collar trade unions make the buyer and seller much more equally powerful when they negotiate the price for a working hour. When the customer and seller are equally powerful, then the price for a commodity is appropriate to both parties.
