In neoclassical economics, market failure is a situation in which the allocation of goods and services by a free market is not Pareto efficient, often leading to a net loss of economic value.John O. Ledyard (2008). Market Failure, The New Palgrave Dictionary of EconomicsPaul Krugman and Robin Wells (2006). Economics, New York, Worth Publishers. The first known use of the term by economists was in 1958,Francis M. Bator (1958). "The Anatomy of Market Failure," Quarterly Journal of Economics, 72(3) pp. 351–379 (press +). but the concept has been traced back to the Victorian writers John Stuart Mill and Henry Sidgwick.JS Mill, Principles of Political Economy (1848) Book V, chapter IX, on exceptions to laissez faireSteven G.

The neoclassical school attributes market failures to the interference of self-regulatory organizations, governments or supra-national institutions in a particular market, although this view is criticized by heterodox economists.Kenneth J. Arrow (1969). "The Organization of Economic Activity: Issues Pertinent to the Choice of Market versus Non-market Allocations," in Analysis and Evaluation of Public Expenditures: The PPP System, Washington, D.C., Joint Economic Committee of Congress. PDF reprint as pp. 1–16 (press +). Economists, especially microeconomists, are often concerned with the causes of market failure and possible means of correction. Such analysis plays an important role in many types of public policy decisions and studies.
However, government policy interventions, such as taxes, subsidies, wage and price controls, and regulations, may also lead to an inefficient allocation of resources, sometimes called government failure. Most mainstream economists believe that there are circumstances (like building codes, fire safety regulations or endangered species laws) in which it is possible for government or other organizations to improve the inefficient market outcome. Several heterodox schools of thought disagree with this as a matter of ideology.
An ecological market failure exists when human activity in a market economy is exhausting critical non-renewable resources, disrupting fragile ecosystems, or overloading biospheric waste absorption capacities. In none of these cases does the criterion of Pareto efficiency obtain.
Categories Different economists have different views about what events are the sources of market failure. Mainstream economic analysis widely accepts that there are several causes of market failures.J Stiglitz and J Rosengard, Economics of the Public Sector (4th edn 2015) chapter 4, 83–94. T Piketty, Capital in the Twenty-First Century (2011) ch 9. D Kahneman, Thinking, Fast and Slow (2011) These include if the market is "monopolised" or a small group of businesses hold significant market power resulting in a "failure of competition"; if production of the good or service results in an externality (external costs or benefits); if the good or service is a "public good"; if there is a "failure of information" or information asymmetry; if there is unequal bargaining power; if there is bounded rationality or irrationality; and if there are macro-economic failures such as unemployment or inflation.
Failure of competition
Agents in a market can gain market power, allowing them to block other mutually beneficial gains from trade from occurring. This can lead to inefficiency due to imperfect competition, which can take many different forms, such as monopolies, monopsonies, or monopolistic competition, if the agent does not implement perfect price discrimination.
It is then a further question about what circumstances allow a monopoly to arise. In some cases, monopolies can maintain themselves where there are "barriers to entry" that prevent other companies from effectively entering and competing in an industry or market. Or there could exist significant first-mover advantages in the market that make it difficult for other firms to compete. Moreover, monopoly can be a result of geographical conditions created by huge distances or isolated locations. This leads to a situation where there are only few communities scattered across a vast territory with only one supplier. Australia is an example that meets this description. A natural monopoly is a firm whose per-unit cost decreases as it increases output; in this situation it is most efficient (from a cost perspective) to have only a single producer of a good. Natural monopolies display so-called increasing returns to scale. It means that at all possible outputs marginal cost needs to be below average cost if average cost is declining. One of the reasons is the existence of fixed costs, which must be paid without considering the amount of output, what results in a state where costs are evenly divided over more units leading to the reduction of cost per unit.
Public goods Some markets can fail due to the nature of the goods being exchanged. For instance, some goods can display the attributes of public goods or common goods, wherein sellers are unable to exclude non-buyers from using a product, as in the development of inventions that may spread freely once revealed, such as developing a new method of harvesting. This can cause underinvestment because developers cannot capture enough of the benefits from success to make the development effort worthwhile. This can also lead to resource depletion in the case of common-pool resources, whereby the use of the resource is rival but non-excludable, there is no incentive for users to conserve the resource. An example of this is a lake with a natural supply of fish: if people catch the fish faster than the fish can reproduce, then the fish population will dwindle until there are no fish left for future generations.
Externalities A good or service could also have significant externalities, where gains or losses associated with the product, production or consumption of a product, differ from the private cost. These gains or losses are imposed on a third-party that did not take part in the original market transaction. These externalities can be innate to the methods of production or other conditions important to the market.
"The Problem of Social Cost" illuminates a different path towards social optimum showing the Pigouvian tax is not the only way towards solving externalities. It is hard to say who discovered externalities first since many classical economists saw the importance of education or a lighthouse, but it was Alfred Marshall who wanted to explore this more. He wondered why long-run supply curve under perfect competition could be decreasing so he founded "external economies".Sandmo 228228 Externalities can be positive or negative depending on how a good/service is produced or what the good/service provides to the public. Positive externalities tend to be goods like vaccines, schools, or advancement of technology. They usually provide the public with a positive gain. Negative externalities would be like noise or air pollution. Coase shows this with his example of the case Sturges v. Bridgman involving a confectioner and doctor. The confectioner had lived there many years and soon the doctor several years into residency decides to build a consulting room; it is right by the confectioner's kitchen which releases vibrations from his grinding of pestle and mortar.The Problem of Social Cost 8 The doctor wins the case by a claim of nuisance so the confectioner would have to cease from using his machine. Coase argues there could have been bargains instead the confectioner could have paid the doctor to continue the source of income from using the machine hopefully it is more than what the Doctor is losing.The Problem of Social Cost 9 Vice versa the doctor could have paid the confectioner to cease production since he is prohibiting a source of income from the confectioner. Coase used a few more examples similar in scope dealing with social cost of an externality and the possible resolutions.
Traffic congestion is an example of market failure that incorporates both non-excludability and externality. Public roads are common resources that are available for the entire population's use (non-excludable), and act as a complement to cars (the more roads there are, the more useful cars become). Because there is very low cost but high benefit to individual drivers in using the roads, the roads become congested, decreasing their usefulness to society. Furthermore, driving can impose hidden costs on society through pollution (externality). Solutions for this include public transportation, congestion pricing, tolls, and other ways of making the driver include the social cost in the decision to drive.
Perhaps the best example of the inefficiency associated with common/public goods and externalities is the environmental harm caused by pollution and overexploitation of natural resources.
Coase theorem The Coase theorem, developed by Ronald Coase and labeled as such by George Stigler, states that private transactions are efficient as long as property rights exist, only a small number of parties are involved, and transactions costs are low. Additionally, this efficiency will take place regardless of who owns the property rights. This theory comes from a section of Coase's Nobel prize-winning work The Problem of Social Cost. While the assumptions of low transactions costs and a small number of parties involved may not always be applicable in real-world markets, Coase's work changed the long-held belief that the owner of property rights was a major determining factor in whether or not a market would fail.Michael Parkin (2008). Microeconomics, 9th Ed. p. 379. University of Western Ontario. The Coase theorem points out when one would expect the market to function properly even when there are externalities.
A market is an institution in which individuals or firms exchange not just commodities, but the rights to use them in particular ways for particular amounts of time. [...] Markets are institutions which organize the exchange of control of commodities, where the nature of the control is defined by the property rights attached to the commodities.
