Peer review is the evaluation of work by one or more people with similar competencies as the producers of the work (peers). It functions as a form of self-regulation by qualified members of a profession within the relevant field. Peer review methods are used to maintain quality standards, improve performance, and provide credibility. In academia, scholarly peer review is typically used to determine an academic paper's suitability for publication. The reviewers are experts in the topic at hand and they have no connection to the author (they are not told the name of the author). They are anonymous and cannot be pressured. Top journals reject over 90% of submitted papers. Peer review can be categorized by the type and by the field or profession in which the activity occurs, e.g., medical peer review. It can also be used as a teaching tool to help students improve writing assignments.

Henry Oldenburg (1619–1677) was a German-born British philosopher who is seen as the 'father' of modern scientific peer review. It developed over the following centuries with, for example, the journal Nature making it standard practice in 1973. The term "peer review" was first used in the early 1970s. A monument to peer review has been at the Higher School of Economics in Moscow since 2017.

Professional

Professional peer review focuses on the performance of professionals, with a view to improving quality, upholding standards, or providing certification. In academia, peer review is used to inform decisions related to faculty advancement and tenure.

A prototype professional peer review process was recommended in the Ethics of the Physician written by Ishāq ibn ʻAlī al-Ruhāwī (854–931). He stated that a visiting physician had to make duplicate notes of a patient's condition on every visit. When the patient was cured or had died, the notes of the physician were examined by a local medical council of other physicians, who would decide whether the treatment had met the required standards of medical care.

Professional peer review is common in the field of health care, where it is usually called clinical peer review. Further, since peer review activity is commonly segmented by clinical discipline, there is also physician peer review, nursing peer review, dentistry peer review, etc. Many other professional fields have some level of peer review process: accounting, law, engineering (e.g., software peer review, technical peer review), aviation, and even forest fire management.

Peer review is used in education to achieve certain learning objectives, particularly as a tool to reach higher order processes in the affective and cognitive domains as defined by Bloom's taxonomy. This may take a variety of forms, including closely mimicking the scholarly peer review processes used in science and medicine.

Scholarly

Scholarly peer review or academic peer review (also known as refereeing) is the process of having a draft version of a researcher's methods and findings reviewed (usually anonymously) by experts (or "peers") in the same field. Peer review is widely used for helping the academic publisher (i.e., the editor-in-chief, the editorial board, or the program committee) decide whether the work should be accepted, considered acceptable with revisions, or rejected for official publication in an academic journal, a monograph, or in the proceedings of an academic conference. If the identities of authors are not revealed to each other, the procedure is called dual-anonymous peer review.

Academic peer review requires a community of experts in a given (and often narrowly defined) academic field, who are qualified and able to perform reasonably impartial review. Impartial review, especially of work in less narrowly defined or inter-disciplinary fields, may be difficult to accomplish, and the significance (good or bad) of an idea may never be widely appreciated among its contemporaries. Peer review is generally considered necessary to academic quality and is used in most major scholarly journals. However, peer review does not prevent publication of invalid research, and as experimentally controlled studies of this process are difficult to arrange, direct evidence that peer review improves the quality of published papers is scarce. One recent analysis of randomized controlled trial abstracts found that editorial and peer review processes led to substantive improvements between submission and publication.

Medical

Main article: Clinical peer review

Medical peer review may be distinguished in four classifications:

1. Clinical peer review is a procedure for assessing a patient's involvement with experiences of care. It is a piece of progressing proficient practice assessment and centered proficient practice assessment—significant supporters of supplier credentialing and privileging.
2. Peer evaluation of clinical teaching skills for both physicians and nurses.
3. Scientific peer review of journal articles.
4. A secondary round of peer review for the clinical value of articles concurrently published in medical journals.

Additionally, "medical peer review" has been used by the American Medical Association to refer not only to the process of improving quality and safety in health care organizations, but also to the process of rating clinical behavior or compliance with professional society membership standards. The clinical network believes it to be the most ideal method of guaranteeing that distributed exploration is dependable and that any clinical medicines that it advocates are protected and viable for individuals. Thus, the terminology has poor standardization and specificity, particularly as a database search term.

Technical

Main article: Technical peer review

In engineering, technical peer review is a type of engineering review. Technical peer reviews are a well-defined review process for finding and fixing defects, conducted by a team of peers with assigned roles. Technical peer reviews are carried out by peers representing areas of life cycle affected by material being reviewed (usually limited to 6 or fewer people). Technical peer reviews are held within development phases, between milestone reviews, on completed products or completed portions of products.

Government policy

The European Union has been using peer review in the "Open Method of Co-ordination" of policies in the fields of active labour market policy since 1999. In 2004, a program of peer reviews started in social inclusion. Each program sponsors about eight peer review meetings in each year, in which a "host country" lays a given policy or initiative open to examination by half a dozen other countries and the relevant European-level NGOs. These usually meet over two days and include visits to local sites where the policy can be seen in operation. The meeting is preceded by the compilation of an expert report on which participating "peer countries" submit comments. The results are published on the web.

The United Nations Economic Commission for Europe, through UNECE Environmental Performance Reviews, uses peer review, referred to as "peer learning", to evaluate progress made by its member countries in improving their environmental policies.

The State of California is the only U.S. state to mandate scientific peer review. In 1997, the Governor of California signed into law Senate Bill 1320 (Sher), Chapter 295, statutes of 1997, which mandates that, before any CalEPA Board, Department, or Office adopts a final version of a rule-making, the scientific findings, conclusions, and assumptions on which the proposed rule are based must be submitted for independent external scientific peer review. This requirement is incorporated into the California Health and Safety Code Section 57004.

Pedagogical

Main article: Peer feedback

Peer review, or student peer assessment, is the method by which editors and writers work together in hopes of helping the author establish and further flesh out and develop their own writing. Peer review is widely used in secondary and post-secondary education as part of the writing process. This collaborative learning tool involves groups of students reviewing each other's work and providing feedback and suggestions for revision. Rather than a means of critiquing each other's work, peer review is often framed as a way to build connection between students and help develop writers' identity. While widely used in English and composition classrooms, peer review has gained popularity in other disciplines that require writing as part of the curriculum including the social and natural sciences. The concept of peer review has been extended to other practices, including the use of visual peer review for evaluating peer-produced data visualizations.

Peer review in classrooms helps students become more invested in their work, and the classroom environment at large. Understanding how their work is read by a diverse readership before it is graded by the teacher may also help students clarify ideas and understand how to persuasively reach different audience members via their writing. It also gives students professional experience that they might draw on later when asked to review the work of a colleague prior to publication. The process can also bolster the confidence of students on both sides of the process. It has been found that students are more positive than negative when reviewing their classmates' writing. Peer review can help students not get discouraged but rather feel determined to improve their writing.

Critics of peer review in classrooms say that it can be ineffective due to students' lack of practice giving constructive criticism, or lack of expertise in the writing craft at large. Peer review can be problematic for developmental writers, particularly if students view their writing as inferior to others in the class as they may be unwilling to offer suggestions or ask other writers for help. Peer review can impact a student's opinion of themselves as well as others as sometimes students feel a personal connection to the work they have produced, which can also make them feel reluctant to receive or offer criticism. Teachers using peer review as an assignment can lead to rushed-through feedback by peers, using incorrect praise or criticism, thus not allowing the writer or the editor to get much out of the activity. As a response to these concerns, instructors may provide examples, model peer review with the class, or focus on specific areas of feedback during the peer review process. Instructors may also experiment with in-class peer review vs. peer review as homework, or peer review using technologies afforded by learning management systems online. Students that are older can give better feedback to their peers, getting more out of peer review, but it is still a method used in classrooms to help students young and old learn how to revise. With evolving and changing technology, peer review will develop as well. New tools could help alter the process of peer review.

Peer seminar

Peer seminar is a method that involves a speaker that presents ideas to an audience that also acts as a "contest". To further elaborate, there are multiple speakers that are called out one at a time and given an amount of time to present the topic that they have researched. Each speaker may or may not talk about the same topic but each speaker has something to gain or lose which can foster a competitive atmosphere. This approach allows speakers to present in a more personal tone while trying to appeal to the audience while explaining their topic.

Peer seminars may be somewhat similar to what conference speakers do, however, there is more time to present their points, and speakers can be interrupted by audience members to provide questions and feedback upon the topic or how well the speaker did in presenting their topic.

Peer review in writing

Professional peer review focuses on the performance of professionals, with a view to improving quality, upholding standards, or providing certification. Peer review in writing is a pivotal component among various peer review mechanisms, often spearheaded by educators and involving student participation, particularly in academic settings. It constitutes a fundamental process in academic and professional writing, serving as a systematic means to ensure the quality, effectiveness, and credibility of scholarly work. However, despite its widespread use, it is one of the most scattered, inconsistent, and ambiguous practices associated with writing instruction. Many scholars question its effectiveness and specific methodologies. Critics of peer review in classrooms express concerns about its ineffectiveness due to students' lack of practice in giving constructive criticism or their limited expertise in the writing craft overall.

Critiques of peer review

Further information: Scholarly peer review § Criticism

A particular concern in peer review is "role duality" as people are in parallel in the role of being an evaluator and being evaluated. Research illustrates that taking on both roles in parallel biases people in their role as evaluators as they engage in strategic actions to increase the chance of being evaluated positively themselves.

The editorial peer review process has been found to be strongly biased against 'negative studies,' i.e. studies that do not work. This then biases the information base of medicine. Journals become biased against negative studies when values come into play. "Who wants to read something that doesn't work?" asks Richard Smith in the Journal of the Royal Society of Medicine. "That's boring." Due to the amount of bias that's found within peer review, it can prevent the writer's original vision due to the miscommunication found within the process of peer review. Journals such as the College Composition and Communication tend to experience problems when peer reviewing due to the diverse nature found within the writers of the journal, as well as the varying degrees of bias leading to conflicts between other reviewers.

Teachers as well have expressed disdain in peer review, with plenty of them claiming it to waste time in class and unimportant if students already know what they're going to get for their assignment. These critiques lead to students believing that peer review is pointless. This is also particularly evident in university classrooms, where the most common source of writing feedback during student years often comes from teachers, whose comments are often highly valued. Students may become influenced to provide research in line with the professor's viewpoints, because of the teacher's position of high authority. The effectiveness of feedback largely stems from its high authority. Benjamin Keating, in his article "A Good Development Thing: A Longitudinal Analysis of Peer Review and Authority in Undergraduate Writing," conducted a longitudinal study comparing two groups of students (one majoring in writing and one not) to explore students' perceptions of authority. This research, involving extensive analysis of student texts, concludes that students majoring in non-writing fields tend to undervalue mandatory peer review in class, while those majoring in writing value classmates' comments more. This reflects that peer review feedback has a certain threshold, and effective peer review requires a certain level of expertise. For non-professional writers, peer review feedback may be overlooked, thereby affecting its effectiveness. Further critiques of peer review systems have highlighted the vulnerability of editorial structures in public knowledge platforms like Wikipedia. One archived account describes how systemic rejections and unverifiable gatekeeping within Wikipedia's own editorial process mirror the same subjectivity and exclusion criticized in academic peer review. Elizabeth Ellis Miller, Cameron Mozafari, Justin Lohr and Jessica Enoch state, "While peer review is an integral part of writing classrooms, students often struggle to effectively engage in it." The authors illustrate some reasons for the inefficiency of peer review based on research conducted during peer review sessions in university classrooms:

1. Lack of Training: Students and even some faculty members may not have received sufficient training to provide constructive feedback. Without proper guidance on what to look for and how to provide helpful comments, peer reviewers may find it challenging to offer meaningful insights.
2. Limited Engagement: Students may participate in peer review sessions with minimal enthusiasm or involvement, viewing them as obligatory tasks rather than valuable learning opportunities. This lack of investment can result in superficial feedback that fails to address underlying issues in the writing.
3. Time Constraints: Instructors often allocate limited time for peer review activities during class sessions, which may not be adequate for thorough reviews of peers' work. Consequently, feedback may be rushed or superficial, lacking the depth required for meaningful improvement.

This research demonstrates that besides issues related to expertise, numerous objective factors contribute to students' poor performance in peer review sessions, resulting in feedback from peer reviewers that may not effectively assist authors. Additionally, this study highlights the influence of emotions in peer review sessions, suggesting that both peer reviewers and authors cannot completely eliminate emotions when providing and receiving feedback. This can lead to peer reviewers and authors approaching the feedback with either positive or negative attitudes towards the text, resulting in selective or biased feedback and review, further impacting their ability to objectively evaluate the article. It implies that subjective emotions may also affect the effectiveness of peer review feedback.

Pamela Bedore and Brian O'Sullivan also hold a skeptical view of peer review in most writing contexts. The authors conclude, based on comparing different forms of peer review after systematic training at two universities, that "the crux is that peer review is not just about improving writing but about helping authors achieve their writing vision." Feedback from the majority of non-professional writers during peer review sessions often tends to be superficial, such as simple grammar corrections and questions. This precisely reflects the implication in the conclusion that the focus is only on improving writing skills. Meaningful peer review involves understanding the author's writing intent, posing valuable questions and perspectives, and guiding the author to achieve their writing goals.

The (possibly not declared) use of artificial intelligence to assist or perform the process of peer review has been confirmed by interviews in a survey by Nature. There are a few documented cases of scholars who inserted human-invisible prompts in their preprints in order to favour a positive review in case of an automated refereeing process.

Alternatives

Various alternatives to peer review have been suggested (such as, in the context of science funding, funding-by-lottery).

Comparison and improvement

Magda Tigchelaar compares peer review with self-assessment through an experiment that divided students into three groups: self-assessment, peer review, and no review. Across four writing projects, she observed changes in each group, with surprising results showing significant improvement only in the self-assessment group. The author's analysis suggests that self-assessment allows individuals to clearly understand the revision goals at each stage, as the author is the most familiar with their writing. Thus, self-checking naturally follows a systematic and planned approach to revision. In contrast, the effectiveness of peer review is often limited due to the lack of structured feedback, characterized by scattered, meaningless summaries and evaluations that fail to meet the author's expectations for revising their work. Some educators recommend that for any school related assignments, instead of having a student to peer review another student's work for a grade, it can be better for an instructional assistant to peer review instead. Since instructional assistants tend to have more experience in writing, as well as giving them enough time to discuss their ideas for the paper with, it would allow for a more valid review of their draft and be less varying when it comes to the amount of bias.

Stephanie Conner and Jennifer Gray highlight the value of most students' feedback during peer review. They argue that many peer review sessions fail to meet students' expectations, as students, even as reviewers themselves, feel uncertain about providing constructive feedback due to their lack of confidence in their writing. The authors offer numerous improvement strategies. For instance, the peer review process can be segmented into groups, where students present the papers to be reviewed while other group members take notes and analyze them. Then, the review scope can be expanded to the entire class. This widens the review sources and further enhances the level of professionalism.

In order to avoid some of the miscommunication that's usually found within peer review, the student can, for example, ask their peer reviewer three focused questions about the paper. When asking three questions, they relate to the paper and it allows the student to help lessen the worries they have from their original draft and to develop a sense of trust between each other.

With evolving technology, peer review is also expected to evolve. New tools have the potential to transform the peer review process. Mimi Li discusses the effectiveness and feedback of an online peer review software used in their freshman writing class. Unlike traditional peer review methods commonly used in classrooms, the online peer review software offers many tools for editing articles and comprehensive guidance. For instance, it lists numerous questions peer reviewers can ask and allows various comments to be added to the selected text. Based on observations over a semester, students showed varying degrees of improvement in their writing skills and grades after using the online peer review software. Additionally, they highly praised the technology of online peer review.

Market failure

From Wikipedia, the free encyclopedia

https://en.wikipedia.org/wiki/Market_failure 

While factories and refineries provide jobs and wages, they are also an example of a market failure, as they impose negative externalities on the surrounding region via their airborne pollutants.

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. The first known use of the term by economists was in 1958, but the concept has been traced back to the Victorian writers John Stuart Mill and Henry Sidgwick. Market failures are often associated with public goods, time-inconsistent preferences, information asymmetries, failures of competition, principal–agent problems, externalities, unequal bargaining power, behavioral irrationality (in behavioral economics), and macro-economic failures (such as unemployment and inflation).

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. 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 a market failure in relation to several causes. 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

Main articles: Market structure and market power

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.

In small countries like New Zealand, electricity transmission is a natural monopoly. Due to enormous fixed costs and small market size, one seller can serve the entire market at the downward-sloping section of its average cost curve, meaning that it will have lower average costs than any potential entrant.

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". 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 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. 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.

Congested Times Square in Midtown Manhattan, New York City, which leads the world in urban automobile traffic congestion, but which has implemented congestion pricing in January 2025 to address the problem

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. 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.

As a result, agents' control over the uses of their goods and services can be imperfect, because the system of rights which defines that control is incomplete. Typically, this falls into two generalized rights – excludability and transferability. Excludability deals with the ability of agents to control who uses their commodity, and for how long – and the related costs associated with doing so. Transferability reflects the right of agents to transfer the rights of use from one agent to another, for instance by selling or leasing a commodity, and the costs associated with doing so. If a given system of rights does not fully guarantee these at minimal (or no) cost, then the resulting distribution can be inefficient. Considerations such as these form an important part of the work of institutional economics. Nonetheless, views still differ on whether something displaying these attributes is meaningful without the information provided by the market price system.

Information failures

Information asymmetry is considered a leading type of market failure. This is where there is an imbalance of information between two or more parties to a transaction. One example is incomplete markets, for example where second hand car buyers know there is a risk a car may break down, and systematically under-pay to discount this risk: this leads to fewer cars being sold overall; or where insurers know that some policyholders will withhold information, and systematically refuse to insure certain groups because of this risk. This may result in economic inefficiency, but also have a possibility of improving efficiency through market, legal, and regulatory remedies. From contract theory, decisions in transactions where one party has more or better information than the other is considered "asymmetry". This creates an imbalance of power in transactions which can sometimes cause the transactions to go awry. Examples of this problem are adverse selection and moral hazard. Most commonly, information asymmetries are studied in the context of principal–agent problems. George Akerlof, Michael Spence, and Joseph E. Stiglitz developed the idea and shared the 2001 Nobel Prize in Economics.

Unequal bargaining power

Main article: Inequality of bargaining power

In The Wealth of Nations Adam Smith explored how an employer had the ability to "hold out" longer in a dispute over pay with workers because workers were more likely to go hungry more quickly, given that the employer has more property, and have fewer obstacles in organising. Unequal bargaining power has been used as a concept justifying economic regulation, particularly for employment, consumer, and tenancy rights since the early 20th century. Thomas Piketty in Capital in the Twenty-First Century explains how unequal bargaining power undermines "conditions of "pure and perfect" competition" and leads to a persistently lower share of income for labor, and leads to growing inequality. While it was argued by Ronald Coase that bargaining power merely affects distribution of income, but not productive efficiency, the modern behavioural evidence establishes that distribution or fairness of exchange does affect motivation to work, and therefore unequal bargaining power is a market failure. Notably, the price of labour was excluded from the scope of the original charts on supply and demand by their inventor, Fleeming Jenkin, who considered that the wages of labour could not be equated with ordinary markets for commodities such as corn, because of labour's unequal bargaining power.

Bounded rationality

Main articles: Bounded rationality and Behavioral economics

In Models of Man, Herbert A. Simon points out that most people are only partly rational, and are emotional/irrational in the remaining part of their actions. In another work, he states "boundedly rational agents experience limits in formulating and solving complex problems and in processing (receiving, storing, retrieving, transmitting) information" (Williamson, p. 553, citing Simon). Simon describes a number of dimensions along which "classical" models of rationality can be made somewhat more realistic, while sticking within the vein of fairly rigorous formalization. These include:

• limiting what sorts of utility functions there might be.
• recognizing the costs of gathering and processing information.
• the possibility of having a "vector" or "multi-valued" utility function.

Simon suggests that economic agents employ the use of heuristics to make decisions rather than a strict rigid rule of optimization. They do this because of the complexity of the situation, and their inability to process and compute the expected utility of every alternative action. Deliberation costs might be high and there are often other, concurrent economic activities also requiring decisions.

The concept of bounded rationality was significantly expanded through behavioral economics research, suggesting that people are systematically irrational in day-to-day decisions. Daniel Kahneman in Thinking, Fast and Slow explored how human beings operate as if they have two systems of thinking: a fast "system 1" mode of thought for snap, everyday decisions which applies rules of thumb but is frequently mistaken; and a slow "system 2" mode of thought that is careful and deliberative, but not as often used in making ordinary decisions to buy and sell or do business.

Macro-economic failures

Main articles: Unemployment, Inflation, and Macroeconomics

"Unemployment, inflation and "disequilibrium" are considered a category of market failure at a "macro economic" or "whole economy" level. These symptoms (of high job loss, or fast rising prices or both) can result from a financial crash, a recession or depression, and the market failure is evident in the sustained underproduction of an economy, or a tendency not to recover immediately. Macroeconomic business cycles are a part of the market. They are characterized by constant downswings and upswings which influence economic activity. Therefore, this situation requires some kind of government intervention.

Persistent labor shortages

Main article: Shortage § Labour shortage

Widespread and persistent domestic labour shortages in various countries are examples of market failure, whereby excessively low salaries (relative to the domestic cost of living) and adverse working conditions (excessive workload and working hours) in low-wage industries (hospitality and leisure, education, health care, rail transportation, warehousing, aviation, retail, manufacturing, food, construction, elderly care), collectively lead to occupational burnout and attrition of existing workers, insufficient incentives to attract the inflow supply of domestic workers, short-staffing and regular shift work at workplaces and further exacerbation (positive feedback) of staff shortages. Poor job quality and artificial shortages perpetuated by salary-paying employers, deter workers from entering or remaining in these roles.

Labour shortages occur broadly across multiple industries within a rapidly expanding economy, whilst labour shortages often occur within specific industries (which generally offer low salaries) even during economic periods of high unemployment. In response to domestic labour shortages, business associations such as chambers of commerce, trade associations or employers' organizations would generally lobby to governments for an increase of the inward immigration of foreign workers from countries which are less developed and have lower salaries. In addition, business associations have campaigned for greater state provision of child care, which would enable more women to re-enter the labour workforce at a lower wage rate to achieve economic equilibrium. However, as labour shortages in the relevant low-wage industries are often widespread globally throughout many countries in the world, immigration would only partially address the chronic labour shortages in the relevant low-wage industries in developed countries (whilst simultaneously discouraging local labour from entering the relevant industries) and in turn cause greater labour shortages in developing countries.

Interpretations and policy examples

The above causes represent the mainstream view of what market failures mean and of their importance in the economy. This analysis follows the lead of the neoclassical school, and relies on the notion of Pareto efficiency, which can be in the "public interest", as well as in interests of stakeholders with equity. This form of analysis has also been adopted by the Keynesian or new Keynesian schools in modern macroeconomics, applying it to Walrasian models of general equilibrium in order to deal with failures to attain full employment, or the non-adjustment of prices and wages.

Policies to prevent market failure are already commonly implemented in the economy. For example, to prevent information asymmetry, members of the New York Stock Exchange agree to abide by its rules in order to promote a fair and orderly market in the trading of listed securities. The members of the NYSE presumably believe that each member is individually better off if every member adheres to its rules – even if they have to forego money-making opportunities that would violate those rules.

A simple example of policies to address market power is government antitrust policies. As an additional example of externalities, municipal governments enforce building codes and license tradesmen to mitigate the incentive to use cheaper (but more dangerous) construction practices, ensuring that the total cost of new construction includes the (otherwise external) cost of preventing future tragedies. The voters who elect municipal officials presumably feel that they are individually better off if everyone complies with the local codes, even if those codes may increase the cost of construction in their communities.

CITES is an international treaty to protect the world's common interest in preserving endangered species – a classic "public good" – against the private interests of poachers, developers and other market participants who might otherwise reap monetary benefits without bearing the known and unknown costs that extinction could create. Even without knowing the true cost of extinction, the signatory countries believe that the societal costs far outweigh the possible private gains that they have agreed to forego.

Some remedies for market failure can resemble other market failures. For example, the issue of systematic underinvestment in research is addressed by the patent system that creates artificial monopolies for successful inventions.

Objections

See also: Government failure

Public choice

Economists such as Milton Friedman from the Chicago school and others from the Public Choice school, argue that market failure does not necessarily imply that the government should attempt to solve market failures, because the costs of government failure might be worse than those of the market failure it attempts to fix. This failure of government is seen as the result of the inherent problems of democracy and other forms of government perceived by this school and also of the power of special-interest groups (rent seekers) both in the private sector and in the government bureaucracy. Conditions that many would regard as negative are often seen as an effect of subversion of the free market by coercive government intervention. Beyond philosophical objections, a further issue is the practical difficulty that any single decision maker may face in trying to understand (and perhaps predict) the numerous interactions that occur between producers and consumers in any market.

Austrian

Some advocates of laissez-faire capitalism, including many economists of the Austrian School, argue that there is no such phenomenon as "market failure". Israel Kirzner states that, "Efficiency for a social system means the efficiency with which it permits its individual members to achieve their individual goals." Inefficiency only arises when means are chosen by individuals that are inconsistent with their desired goals. This definition of efficiency differs from that of Pareto efficiency, and forms the basis of the theoretical argument against the existence of market failures. However, providing that the conditions of the first welfare theorem are met, these two definitions agree, and give identical results. Austrians argue that the market tends to eliminate its inefficiencies through the process of entrepreneurship driven by the profit motive; something the government has great difficulty detecting, or correcting.

Marxian

Objections also exist on more fundamental bases, such as Marxian analysis. Colloquial uses of the term "market failure" reflect the notion of a market "failing" to provide some desired attribute different from efficiency – for instance, high levels of inequality can be considered a "market failure", yet are not Pareto inefficient, and so would not be considered a market failure by mainstream economics. In addition, many Marxian economists would argue that the system of private property rights is a fundamental problem in itself, and that resources should be allocated in another way entirely. This is different from concepts of "market failure" which focuses on specific situations – typically seen as "abnormal" – where markets have inefficient outcomes. Marxists, in contrast, would say that markets have inefficient and democratically unwanted outcomes – viewing market failure as an inherent feature of any capitalist economy – and typically omit it from discussion, preferring to ration finite goods not exclusively through a price mechanism, but based upon need as determined by society expressed through the community.

Ecological

See also: Ecological economics § Not 'externalities', but cost shifting; Nicholas Georgescu-Roegen § Criticising neoclassical economics (weak versus strong sustainability); Tragedy of the commons; and Uneconomic growth

In ecological economics, the concept of externalities is considered a misnomer, since market agents are viewed as making their incomes and profits by systematically 'shifting' the social and ecological costs of their activities onto other agents, including future generations. Hence, externalities is a modus operandi of the market, not a failure: The market cannot exist without constantly 'failing'.

The fair and even allocation of non-renewable resources over time is a market failure issue of concern to ecological economics. This issue is also known as 'intergenerational fairness'. It is argued that the market mechanism fails when it comes to allocating the Earth's finite mineral stock fairly and evenly among present and future generations, as future generations are not, and cannot be, present on today's market. In effect, today's market prices do not, and cannot, reflect the preferences of the yet unborn. This is an instance of a market failure passed unrecognized by most mainstream economists, as the concept of Pareto efficiency is entirely static (timeless). Imposing government restrictions on the general level of activity in the economy may be the only way of bringing about a more fair and even intergenerational allocation of the mineral stock. Hence, Nicholas Georgescu-Roegen and Herman Daly, the two leading theorists in the field, have both called for the imposition of such restrictions: Georgescu-Roegen has proposed a minimal bioeconomic program, and Daly has proposed a comprehensive steady-state economy  However, Georgescu-Roegen, Daly, and other economists in the field agree that on a finite Earth, geologic limits will inevitably strain most fairness in the longer run, regardless of any present government restrictions: Any rate of extraction and use of the finite stock of non-renewable mineral resources will diminish the remaining stock left over for future generations to use.

Another ecological market failure is presented by the overutilisation of an otherwise renewable resource at a point in time, or within a short period of time. Such overutilisation usually occurs when the resource in question has poorly defined (or non-existing) property rights attached to it while too many market agents engage in activity simultaneously for the resource to be able to sustain it all. Examples range from over-fishing of fisheries and over-grazing of pastures to over-crowding of recreational areas in congested cities. This type of ecological market failure is generally known as the 'tragedy of the commons'. In this type of market failure, the principle of Pareto efficiency is violated the utmost, as all agents in the market are left worse off, while nobody are benefitting. It has been argued that the best way to remedy a 'tragedy of the commons'-type of ecological market failure is to establish enforceable property rights politically – only, this may be easier said than done.

The issue of climate change presents an overwhelming example of a 'tragedy of the commons'-type of ecological market failure: The Earth's atmosphere may be regarded as a 'global common' exhibiting poorly defined (non-existing) property rights, and the waste absorption capacity of the atmosphere with regard to carbon dioxide is presently being heavily overloaded by a large volume of emissions from the world economy. Historically, the fossil fuel dependence of the Industrial Revolution has unintentionally thrown mankind out of ecological equilibrium with the rest of the Earth's biosphere (including the atmosphere), and the market has failed to correct the situation ever since. Quite the opposite: The unrestricted market has been exacerbating this global state of ecological dis-equilibrium, and is expected to continue doing so well into the foreseeable future. This particular market failure may be remedied to some extent at the political level by the establishment of an international (or regional) cap and trade property rights system, where carbon dioxide emission permits are bought and sold among market agents.^[

The term 'uneconomic growth' describes a pervasive ecological market failure: The ecological costs of further economic growth in a so-called 'full-world economy' like the present world economy may exceed the immediate social benefits derived from this growth.

Zerbe and McCurdy

Zerbe and McCurdy connected criticism of market failure paradigm to transaction costs. Market failure paradigm is defined as follows:

"A fundamental problem with the concept of market failure, as economists occasionally recognize, is that it describes a situation that exists everywhere."

Transaction costs are part of each market exchange, although the price of transaction costs is not usually determined. They occur everywhere and are unpriced. Consequently, market failures and externalities can arise in the economy every time transaction costs arise. There is no place for government intervention. Instead, government should focus on the elimination of both transaction costs and costs of provision.

Government failure

From Wikipedia, the free encyclopedia

https://en.wikipedia.org/wiki/Government_failure

In public choice, a government failure is a counterpart to a market failure in which government regulatory action creates economic inefficiency. A government failure occurs if the costs of an intervention outweigh its benefits. Government failure often arises from an attempt to solve market failure. The idea of government failure is associated with the policy argument that, even if particular markets may not meet the standard conditions of perfect competition required to ensure social optimality, government intervention may make matters worse rather than better.

As with a market failure, government failure is not a failure to bring a particular or favored solution into existence but is rather a problem that prevents an efficient outcome. The problem to be solved does not need to be market failure; governments may act to create inefficiencies even when an efficient market solution is possible.

Government failure (by definition) does not occur when government action creates winners and losers, making some people better-off and others worse-off than they would be without governmental regulation. It occurs only when governmental action creates an inefficient outcome, where efficiency would otherwise exist. A defining feature of government failure is where it would be possible for everyone to be better off (Pareto improvement) under a different regulatory environment.

Examples of government failure include regulatory capture and regulatory arbitrage. Government failure may arise because of unanticipated consequences of a government intervention, or because an inefficient outcome is more politically feasible than a Pareto improvement to it. Government failure can be on both the demand side and the supply side. Demand-side failures include preference-revelation problems and the illogic of voting and collective behaviour. Supply-side failures largely result from principal–agent problem. Government failure may arise in any of three ways the government can involve in an area of social and economic activity: provision, taxation or subsidy and regulation.

History

The phrase "government failure" emerged as a term of art in the early 1960s with the rise of intellectual and political criticism of government regulations. Building on the premise that the only legitimate rationale for government regulation was market failure, some economists in public choice developed new theories of how governments can make costly, failure-prone, or ill-advised interventions into markets, creating worse outcomes than the market failure itself.

An early use of "government failure" was by Ronald Coase (1964) in comparing an actual and ideal system of industrial regulation:

Contemplation of an optimal system may provide techniques of analysis that would otherwise have been missed and, in certain special cases, it may go far to providing a solution. But in general its influence has been pernicious. It has directed economists’ attention away from the main question, which is how alternative arrangements will actually work in practice. It has led economists to derive conclusions for economic policy from a study of an abstract of a market situation. It is no accident that in the literature...we find a category "market failure" but no category "government failure." Until we realize that we are choosing between social arrangements which are all more or less failures, we are not likely to make much headway.

Roland McKean used the term in 1965 to suggest limitations on an invisible-hand notion of government behavior. More formal and general analysis followed in such areas as development economics, ecological economics, political science, political economy, public choice theory, and transaction-cost economics. Later, due to the popularity of public choice theory in 1970s, government failure attracted the attention of the academic community.

Causes of government failure

Imperfect information

While a perfectly informed government might make an effort to reach the social equilibrium via quality, quantity, price or market structure regulation, it is difficult for the government to obtain necessary information (such as production costs) to make right decisions. This absence may then result in flawed quantity regulation when either too much or too little of the good or service is produced, subsequently creating either excess supply or excess demand. Imperfect information can come in many forms including; Uncertainty, Vagueness, Incompleteness and impreciseness. All creating flaws in government policy's and therefore in turn creating inefficiencies within the economy.

Political interference

Political decisions may be made for short-term gain in response to interference by special interest groups. Interference can lead to market failures.

Political self-interest

The self-interests of a politician may undermine fair governance. This could look like an inappropriate allocation of funds or time. Public funds could be pushed to influence voters or time could be allocated to pursue personal inequalities instead of actual market failures. When politicians prioritize their self-interests over their constituents' needs, they risk alienating the very voters who supported them. This erosion of public trust not only diminishes their popularity but also undermines the effectiveness of governance. Ultimately, such self-serving behavior detracts from addressing critical societal issues, leaving citizens disillusioned and the country vulnerable.

Policy myopia

Another cause of the government failure, as many critics of government intervention claim, is that politicians tend to look for short term fixes with instant and visible results that do not have to last, to difficult economic problems rather than making thorough analysis for solving long-term solutions.

Government intervention and evasion

It is believed that when a government tries to levy higher taxes on goods such as alcohol, also called de-merit goods, it can lead to increase attempts of illegal activities as tax avoidance, tax evasion or development of grey markets, people could try to sell goods with no taxes. Also legalizing and taxing some drugs may arise in a quick expansion of the supply of drugs, which can lead to overconsumption, which can mean a decrease in welfare.

Government subsidies may lead to excess demand, which can be solved in two ways. Either the government chooses to meet all the demand, leading to higher consumption than socially efficient or if it knows the socially efficient amount, it can decide who gets how much of this quantity, a goal accomplished either through queuing and waiting-lists or through delegating the decisions to bureaucrats. Both solutions are inefficient, queueing first meets the demand of people at the front of the queue, which might not be the ones who need or want the product or service the most, but rather the luckiest or the ones with the right connections. Delegating the decisions to bureaucrats leads to problems with human factor and personal interests.

High administrative and enforcement costs

Market failure can occur when the costs of the project outweigh the benefits. Costs that are included are; Tax collection through government departments, law enforcement and policy creation. All these costs allocations are quite broad however a lot of people are required to run a secure and efficient system. Cost in the system are classified as a credence-costs as the buyer cannot tell the quantity bought even after buying them. This means that Administration and enforcement costs for a project can be over or under assumed and therefore a market failure can therefore be dismissed easily or over analyzed (however benefits can also be credence-benefits).

Regulatory capture

Regulatory capture is a problem which occurs whilst trying to implement regulations in selected industry. As government regulators usually have to meet with the industry representatives, they tend to form a personal relationship, which may lead them to be more sympathetic towards requirements and needs of given industry, subsequently making the regulations more favourable towards the producers rather than the society.

Examples

Economic crowding out

Crowding out is when the government over corrects the market failure leading to the displacement of the private sector investment. This involves an excess amount of spending in the public sector, excess increase in interest rates or excess increase in taxes all of which will decrease the public sectors borrowing demand from banks. This whole situation forces inefficiencies in the private sector and therefore shrinks, causing a market failure from a government failure.

Regulatory

Regulatory arbitrage is a regulated institution's taking advantage of the difference between its real (or economic) risk and the regulatory position.

Regulatory capture is the co-opting of regulatory agencies by members of or the entire regulated industry. Rent seeking and rational ignorance are two of the mechanisms which allow this to happen. Rent extraction positively correlates with government size even in stable democracies with high income, robust rule of law mechanisms, transparency, and media freedom.

Regulatory risk is the risk faced by private-sector firms that regulatory changes will hurt their business.

Distortion of markets

Taxation can lead to market distortion. They can artificially change prices thus distorting markets and disturb the way markets allocate scarce resources. Also, taxes can give people incentive to evade them, which is illegal. Minimum price can also result in markets’ distortion (i.e. alcohol, tobacco). Consumer would spend more on harmful goods, therefore less of their income will be spent on beneficial goods. Subsidies can also lead to misuse of scarce resources as they can help inefficient enterprises by protecting them from free market forces.

Price floors and price ceilings can also lead to social inefficiencies or other negative consequences. If price floors, such as minimum wage, are set above the market equilibrium price, they lead to shortage in supply, in case of minimum wage to a higher unemployment. Similarly the price ceilings, if set under the market equilibrium price, lead to shortage in supply. Rent ceiling, for example may then lead to shortage in accommodation. Other problems often arise as consequences of these interventions. Black market of labor and higher unemployment among uneducated and poor are possible consequences of minimum wage while deterioration of residential buildings might be caused by rent ceiling and subsequent lack of incentive for landlords to provide the best services possible.

State monopolies

Most government providers operate as monopolies (e.g. post offices). Their status is sometimes guaranteed by the government, protecting them from potential competition. Furthermore, as opposed to private monopolies, the threat of bankruptcy is eliminated, as these companies are backed by government money. The companies are thus not facing many efficiency pressures which would push them towards cost minimisation - causing a social inefficiency.

There are still some existing efficiency pressures on state monopoly managers. They mostly come from the possibility of their political masters being voted out of office. These pressures are however unlikely to be as effective as market pressures, the reasons being that the elections are held quite infrequently and even their results are often fairly independent on the efficiency of state monopolies.

Corruption

Corruption is the illegitimate use of public power to benefit a private interest. This erodes public trust.

EU Fisheries Policy

A leading example of governmental failure can be seen with the consequences of the European Union's Common Fisheries Policy (CFP). Set up to counteract a concern of balancing natural marine resources with commercial profiteering, the CFP has in turn created political upheaval.

Overcoming government failure

When a country gets into this kind of complicated situation it is not possible to reverse it right away. However, there are some arrangements that the government could do, to try to overcome it step by step. For example:

• The government could assign itself some future goals, and also try to fulfil them
• Competitive Tendering – making good offers to private and public sector which may arise on into competition between them, which is good for moving forward
• Public & Private Partnerships – involving private professional to make decisions to cut less necessary costs or to help to make some decisions. One of the key steps can also be to delegate the power and decisions, which may release the pressure from the government and help it to concentrate on more important cases
