Definition
In economics, a market is a coordinating mechanism that uses prices to convey information among economic entities (such as
firms, households and individuals) to regulate production and distribution. In his seminal 1937 article "
The Nature of the Firm

Ronald Coase
Ronald Harry Coase (; 29 December 1910 – 2 September 2013) was a British economist and author. Coase was educated at the London School of Economics, where he was a member of the faculty until 1951. He was the Clifton R. Musser Professor of Eco ...
wrote: "An economist thinks of the economic system as being coordinated by the price mechanism....in economic theory, we find that the allocation of factors of production between different uses is determined by the price mechanism".
Thus the usage of the price mechanism to convey information is the defining feature of the market. This is in contrast to a firm, which as Coase put it, "the distinguishing mark of the firm is the super-session of the price mechanism".
Thus, Firms and Markets are two opposite forms of organizing production; Coase wrote:
There are also other hybrid forms of coordinating mechanisms, in between the hierarchical firm and price-coordinating market(e.g.

lead to the costs of writing complete contracts. Such theories include: Transaction Cost Economies by
Oliver Williamson and Residual Rights Theory by Groomsman, Hart, and Moore.
The market/firm distinction can be contrasted with the relationship between the agents transacting. While in a market, the relationship is short term and restricted to the contract. In the case of firms and other co-ordinating mechanisms, it is for a longer duration.
In the modern world, much economic activity takes place through fiat and not the market. Lafontaine and Slade (2007) estimates, in the US, that the total value added in transactions inside the firms equal the total value added of all market transactions. Similarly, 80% of all World Trade is conducted under Global Value Chains (2012 estimate), while 33% (1996 estimate) is intra-firm trade. Nearly 50% of US imports and 30% of exports take place within firms. While Rajan and Zingales (1998) have found that in 43 countries two-thirds of the growth in value added between 1980 and 1990 came from increase in firm size.

. The logic behind this thought is that market failure is thought to be caused by other
exogenic systems, and After eliminating external influences or interventions, often referred to as "exogenic systems," the markets were allowed to operate independently, adhering to the principles of free-market economics. This approach assumes that by removing regulatory barriers, subsidies, or other external controls, the market can function more efficiently. The underlying belief is that such "freed" markets, driven by the forces of supply and demand, can self-regulate and allocate resources optimally, thus preventing or minimizing occurrences of market failures. However, this perspective remains a topic of debate among economists and policymakers, as concepts like th
world market return policy along with issues such as monopolies, externalities, and information asymmetries, highlight the complexities of market dynamics.
.
For a market to be competitive, there must be more than a single buyer or seller. It has been suggested that two people may trade, but it takes at least three persons to have a market so that there is competition in at least one of its two sides. However, competitive markets—as understood in formal economic theory—rely on much larger numbers of both buyers and sellers. A market with a single seller and multiple buyers is a

. These are "the polar opposites of perfect competition".
As an argument against such logic, there is a second view that suggests that the source of market failures is inside the market system itself, therefore the removal of other interfering systems would not result in markets with a structure of perfect competition. As an analogy, such an argument may suggest that capitalists do not want to enhance the structure of markets, just like a

'' with a comparable theme of distinguishing perfect from imperfect competition. Chamberlin defined monopolistic competition as "challenge to traditional viewpoint of economics that competition and monopoly are alternatives and that individual prices are to be explained in terms of one or the other". He continues: "By contrast it is held that most economic situations are composite of both competition and monopoly, and that, wherever this is the case, a false view is given by neglecting either one of the two forces and regarding the situation as made up entirely of the other". Hotelling built a model of market located over a line with two sellers in each extreme of the line, in this case maximizing profit for both sellers leads to a stable equilibrium. From this model also follows that if a seller is to choose the location of his store so as to maximize his profit, he will place his store the closest to his competitor as "the sharper competition with his rival is offset by the greater number of buyers he has an advantage". He also argues that clustering of stores is wasteful from the point of view of transportation costs and that public interest would dictate more spatial dispersion.

Stigler sense: the incumbent has no cost discrimination against entrants. He states that a contestable market will never have an economic profit greater than zero when in equilibrium and the equilibrium will also be
efficient. According to Baumol, this equilibrium emerges
endogenously due to the nature of contestable markets; that is, the only industry structure that survives in the long run is the one which minimizes total costs. This is in contrast to the older theory of industry structure since not only is industry structure not
exogenously given, but equilibrium is reached without an ad hoc hypothesis on the behavior of firms, say using reaction functions in a duopoly. He concludes the paper commenting that regulators that seek to impede entry and/or exit of firms would do better to not interfere if the market in question resembles a contestable market.
