Equal opportunity

From Wikipedia, the free encyclopedia

Equal opportunity is a state of fairness in which individuals are treated similarly, unhampered by artificial barriers, prejudices, or preferences, except when particular distinctions can be explicitly justified. For example, the intent of equal employment opportunity is that the important jobs in an organization should go to the people who are most qualified – persons most likely to perform ably in a given task – and not go to persons for reasons deemed arbitrary or irrelevant, such as circumstances of birth, upbringing, having well-connected relatives or friendsreligion, sex, ethnicity, race, caste, or involuntary personal attributes such as disability, age.

According to proponents of the concept, chances for advancement should be open to everybody without regard for wealth, status, or membership in a privileged group. The idea is to remove arbitrariness from the selection process and base it on some "pre-agreed basis of fairness, with the assessment process being related to the type of position" and emphasizing procedural and legal means. Individuals should succeed or fail based on their efforts and not extraneous circumstances such as having well-connected parents. It is opposed to nepotism and plays a role in whether a social structure is seen as legitimate.

The concept is applicable in areas of public life in which benefits are earned and received such as employment and education, although it can apply to many other areas as well. Equal opportunity is central to the concept of meritocracy.

There are two major types of equality: formal equality, the individual merit-based comparison of opportunity, and substantive equality, which moves away from individual merit-based comparison towards group equality of outcomes.

Differing political viewpoints

Equal opportunity for all: "We fight God when our Social System dooms the brilliant clever child of a poor man to the same level as his father", British Admiral Jacky Fisher, Records (1919)

People with differing political viewpoints often view the concept differently. The meaning of equal opportunity is debated in fields such as political philosophy, sociology and psychology. It is being applied to increasingly wider areas beyond employment, including lending, housing, college admissions, voting rights, and elsewhere. In the classical sense, equality of opportunity is closely aligned with the concept of equality before the law and ideas of meritocracy.

Generally, the terms equality of opportunity and equal opportunity are interchangeable, with occasional slight variations; the former has more of a sense of being an abstract political concept while "equal opportunity" is sometimes used as an adjective, usually in the context of employment regulations, to identify an employer, a hiring approach, or the law. Equal opportunity provisions have been written into regulations and have been debated in courtrooms. It is sometimes conceived as a legal right against discrimination. It is an ideal which has become increasingly widespread in Western nations during the last several centuries and is intertwined with social mobility, most often with upward mobility and with rags to riches stories:

The coming President of France is the grandson of a shoemaker. The actual President is a peasant's son. His predecessor again humbly began life in the shipping business. There is surely equality of opportunity under the new order in the old nation.

Theory

Outline of the concept

In a factory setting, equality of opportunity is often seen as a procedural fairness along the lines of "if you assemble twice as many lamps, you'll be paid double" and in this sense the concept is in contrast to the concept of equality of outcome, which might require that all workers be paid similarly regardless of how many lamps they made.

According to the Stanford Encyclopedia of Philosophy, the concept assumes that society is stratified with a diverse range of roles, some of which are more desirable than others. The benefit of equality of opportunity is to bring fairness to the selection process for coveted roles in corporations, associations, nonprofits, universities and elsewhere. According to one view, there is no "formal linking" between equality of opportunity and political structure, in the sense that there can be equality of opportunity in democracies, autocracies and in communist nations, although it is primarily associated with a competitive market economy and embedded within the legal frameworks of democratic societies. People with different political perspectives see equality of opportunity differently: liberals disagree about which conditions are needed to ensure it and many "old-style" conservatives see inequality and hierarchy in general as beneficial out of a respect for tradition. It can apply to a specific hiring decision, or to all hiring decisions by a specific company, or rules governing hiring decisions for an entire nation. The scope of equal opportunity has expanded to cover more than issues regarding the rights of minority groups, but covers practices regarding "recruitment, hiring, training, layoffs, discharge, recall, promotions, responsibility, wages, sick leave, vacation, overtime, insurance, retirement, pensions, and various other benefits".

The concept has been applied to numerous aspects of public life, including accessibility of polling stations, care provided to HIV patients, whether men and women have equal opportunities to travel on a spaceship, bilingual education, skin color of models in Brazil, television time for political candidates, army promotions, admittance to universities and ethnicity in the United States. The term is interrelated with and often contrasted with other conceptions of equality such as equality of outcome and equality of autonomy. Equal opportunity emphasizes the personal ambition and talent and abilities of the individual, rather than his or her qualities based on membership in a group, such as a social class or race or extended family. Further, it is seen as unfair if external factors that are viewed as being beyond the control of a person significantly influence what happens to him or her. Equal opportunity then emphasizes a fair process whereas in contrast equality of outcome emphasizes an equal outcome. In sociological analysis, equal opportunity is seen as a factor correlating positively with social mobility, in the sense that it can benefit society overall by maximizing well-being.

Different types

There are different concepts lumped under equality of opportunity.

Formal equality of opportunity describes equal opportunities based only on merit but these opportunities should not depend on your identity such as gender or race. Formal equality does not guarantee equal outcomes for groups or equal representation of groups, but requires that deliberate discrimination be only meritocratic. For instance, job interviews should only discriminate against applicants based on job competence. Meritocratic universities should not accept a less-capable applicant instead of a more-capable applicant who cannot pay tuition. Formal equality can be called racial color blindness and gender blindness.

Substantive equality describes equal outcomes for groups or equal representation of identities such as gender or race. Substantive does not guarantee equality of opportunity based only on merit. For instance, substantive equality includes that jobs are distributed according to the race and gender proportions of the whole population.

Equality before the law describes where the law does not discriminate explicitly based on protected identity such as gender or race. Equality before the law does not imply Formal equality of opportunity or substantive equality. If firing any pregnant employee is legal, it would meet Equality before the law but would violate both Formal equality of opportunity and substantive equality.

Formal equality of opportunity is often more difficult to measure. A political party that formally allows anyone to join, but meets in a non-wheelchair-accessible building far from public transit, substantively discriminates against both young and old members as they are less likely to be able-bodied car-owners. However, if the party raises membership dues in order to afford a better building, it discourages poor members instead. A workplace in which it is difficult for persons with special needs and disabilities to perform can considered as a type of substantive inequality, although job restructuring activities can be done to make it easier for disabled persons to succeed. Grade-cutoff university admission is formally fair, but if in practice it overwhelmingly picks women and graduates of expensive user-fee schools, it is substantively unfair to men and the poor. The unfairness has already taken place and the university can choose to try to counterbalance it, but it likely can not single-handedly make pre-university opportunities equal. Social mobility and the Great Gatsby curve are often used as an indicator of substantive equality of opportunity.

Both equality concepts say that it is unfair and inefficient if extraneous factors rule people's lives. Both accept as fair inequality based on relevant, meritocratic factors. They differ in the scope of the methods used to promote them. The difference between the two equality concepts is also referred to as Dilemma of Difference.

Formal equality of opportunity

Formal equality of opportunity is sometimes referred to as the nondiscrimination principle or described as the absence of direct discrimination, or described in the narrow sense as equality of access. It is characterized by:

  1. Open call. Positions bringing superior advantages should be open to all applicants and job openings should be publicized in advance giving applicants a "reasonable opportunity" to apply. Further, all applications should be accepted.
  2. Fair judging. Applications should be judged on their merits, with procedures designed to identify those best-qualified. The evaluation of the applicant should be in accord with the duties of the position and for the job opening of choir director, for example, the evaluation may judge applicants based on musical knowledge rather than some arbitrary criterion such as hair color. Blind auditions and blind interviews have been shown to improve equal opportunity.
  3. An application is chosen. The applicant judged as "most qualified" is offered the position while others are not. There is agreement that the result of the process is again unequal, in the sense that one person has the position while another does not, but that this outcome is deemed fair on procedural grounds.

The formal approach is limited to the public sphere as opposed to private areas such as the family, marriage, or religion. What is considered "fair" and "unfair" is spelled out in advance. An expression of this version appeared in The New York Times: "There should be an equal opportunity for all. Each and every person should have as great or as small an opportunity as the next one. There should not be the unfair, unequal, superior opportunity of one individual over another."

The formal conception focuses on procedural fairness during the competition: are the hurdles the same height? (photo: athletes Ulrike Urbansky and Michelle Carey in Osaka)

This sense was also expressed by economists Milton and Rose Friedman in their 1980 book Free to Choose. The Friedmans explained that equality of opportunity was "not to be interpreted literally" since some children are born blind while others are born sighted, but that "its real meaning is ... a career open to the talents". This means that there should be "no arbitrary obstacles" blocking a person from realizing their ambitions: "Not birth, nationality, color, religion, sex, nor any other irrelevant characteristic should determine the opportunities that are open to a person – only his abilities".

It is a relatively straightforward task for legislators to ban blatant efforts to favor one group over another and encourage equality of opportunity as a result. Japan banned gender-specific job descriptions in advertising as well as sexual discrimination in employment as well as other practices deemed unfair, although a subsequent report suggested that the law was having minimal effect in securing Japanese women high positions in management.[48][needs update] In the United States, the Equal Employment Opportunity Commission sued a private test preparation firm, Kaplan, for unfairly using credit histories to discriminate against African Americans in terms of hiring decisions. According to one analysis, it is possible to imagine a democracy which meets the formal criteria (1 through 3), but which still favors wealthy candidates who are selected in free and fair elections.

Meritocracy

There is some overlap among these different conceptions with the term meritocracy which describes an administrative system which rewards such factors as individual intelligence, credentials, education, morality, knowledge or other criteria believed to confer merit. Equality of opportunity is often seen as a major aspect of a meritocracy. One view was that equality of opportunity was more focused on what happens before the race begins while meritocracy is more focused on fairness at the competition stage. The term meritocracy can also be used in a negative sense to refer to a system in which an elite hold themselves in power by controlling access to merit (via access to education, experience, or bias in assessment or judgment).

Therein lies the problem with the idea of equal opportunity for all. Some people are simply better placed to take advantage of opportunity.

— Deborah Orr in The Guardian, 2009

Substantive equality

The Great Gatsby Curve shows that countries with more equality of wealth also have more social mobility, which indicates that equality of wealth and equality of opportunity go together:

If higher inequality makes intergenerational mobility more difficult, it is likely because opportunities for economic advancement are more unequally distributed among children.

Substantive equality of opportunity, sometimes called fair equality of opportunity, is a somewhat broader and more expansive concept than the more limiting formal equality of opportunity and it deals with what is sometimes described as indirect discrimination. It goes farther and is more controversial than the formal variant; and has been described as "unstable", particularly if the society in question is unequal to begin with in terms of great disparity of wealth. The substantive equality embraced by Court of Justice of the European Union focuses on equality of outcomes for group characteristics and group outcomes.

Indirect discrimination rests upon the cardinal assumption that a formally neutral measure is suspicious when it has substantive disadvantages for a formally protected group.

Substantive equality has been identified as more of a left-leaning political position, but this is not a hard-and-fast rule. The substantive model is advocated by people who see limitations in formal equality. In the substantive approach, the starting point before the race begins is unfair since people have had differing experiences before even approaching the competition. The substantive approach examines the applicants themselves before applying for a position and judges whether they have equal abilities or talents; and if not, then it suggests that authorities (usually the government) take steps to make applicants more equal before they get to the point where they compete for a position and fixing the before-the-starting-point issues has sometimes been described as working towards "fair access to qualifications". The success of this approach is evaluated by equality of outcome for disadvantaged and marginalized people and groups.

According to John Hills, children of wealthy and well-connected parents usually have a decisive advantage over other types of children and he notes that "advantage and disadvantage reinforce themselves over the life cycle, and often on to the next generation" so that successful parents pass along their wealth and education to succeeding generations, making it difficult for others to climb up a social ladder. However, so-called positive action efforts to bring an underprivileged person up to speed before a competition begins are limited to the period of time before the evaluation begins. At that point, the "final selection for posts must be made according to the principle the best person for the job", that is, a less qualified applicant should not be chosen over a more qualified applicant. Regardless of the nuances, the overall idea is still to give children from less fortunate backgrounds more of a chance, or to achieve at the beginning what some theorists call equality of condition. Writer Ha-Joon Chang expressed this view:

We can accept the outcome of a competitive process as fair only when the participants have equality in basic capabilities; the fact that no one is allowed to have a head start does not make the race fair if some contestants have only one leg.

In a sense, substantive equality of opportunity moves the "starting point" further back in time. Sometimes it entails the use of affirmative action policies to help all contenders become equal before they get to the starting point, perhaps with greater training, or sometimes redistributing resources via restitution or taxation to make the contenders more equal. It holds that all who have a "genuine opportunity to become qualified" be given a chance to do so and it is sometimes based on a recognition that unfairness exists, hindering social mobility, combined with a sense that the unfairness should not exist or should be lessened in some manner. One example postulated was that a warrior society could provide special nutritional supplements to poor children, offer scholarships to military academies and dispatch "warrior skills coaches" to every village as a way to make opportunity substantively more fair. The idea is to give every ambitious and talented youth a chance to compete for prize positions regardless of their circumstances of birth.

The substantive approach tends to have a broader definition of extraneous circumstances which should be kept out of a hiring decision. One editorial writer suggested that among the many types of extraneous circumstances which should be kept out of hiring decisions was personal beauty, sometimes termed "lookism":

Lookism judges individuals by their physical allure rather than abilities or merit. This naturally works to the advantage of people perceived to rank higher in the looks department. They get preferential treatment at the cost of others. Which fair, democratic system can justify this? If anything, lookism is as insidious as any other form of bias based on caste, creed, gender and race that society buys into. It goes against the principle of equality of opportunity.

The substantive position was advocated by Bhikhu Parekh in 2000 in Rethinking Multiculturalism, in which he wrote that "all citizens should enjoy equal opportunities to acquire the capacities and skills needed to function in society and to pursue their self-chosen goals equally effectively" and that "equalising measures are justified on grounds of justice as well as social integration and harmony".

Affirmative action programs usually fall under the substantive category. The idea is to help disadvantaged groups get back to a normal starting position after a long period of discrimination. The programs involve government action, sometimes with resources being transferred from an advantaged group to a disadvantaged one and these programs have been justified on the grounds that imposing quotas counterbalances the past discrimination as well as being a "compelling state interest" in diversity in society. For example, there was a case in São Paulo in Brazil of a quota imposed on the São Paulo Fashion Week to require that "at least 10 percent of the models to be black or indigenous" as a coercive measure to counteract a "longstanding bias towards white models". It does not have to be accomplished via government action: for example, in the 1980s in the United States, President Ronald Reagan dismantled parts of affirmative action, but one report in the Chicago Tribune suggested that companies remained committed to the principle of equal opportunity regardless of government requirements. In another instance, upper-middle-class students taking the Scholastic Aptitude Test in the United States performed better since they had had more "economic and educational resources to prepare for these test than others". The test itself was seen as fair in a formal sense, but the overall result is seen as unfair in a substantive sense. In India, the Indian Institutes of Technology found that to achieve substantive equality of opportunity the school had to reserve 22.5 percent of seats for applicants from "historically disadvantaged schedule castes and tribes". Elite universities in France began a special "entrance program" to help applicants from "impoverished suburbs".

Luck egalitarianism

Luck egalitarianism views the unequal outcomes that are connected to bad luck of unchosen circumstances as unjust, but just if when connected to circumstances chosen by the individual and that weighing matters such as personal responsibility was important. A somewhat different view was expressed by John Roemer, who used the term nondiscrimination principle to mean that "all individuals who possess the attributes relevant for the performance of the duties of the position in question be included in the pool of eligible candidates, and that an individual's possible occupancy of the position be judged only with respect to those relevant attributes". Matt Cavanagh argued that race and sex should not matter when getting a job, but that the sense of equality of opportunity should not extend much further than preventing straightforward discrimination.

Equality of fair opportunity

Philosopher John Rawls offered this variant of substantive equality of opportunity and explained that it happens when individuals with the same "native talent and the same ambition" have the same prospects of success in competitions. Gordon Marshall offers a similar view with the words "positions are to be open to all under conditions in which persons of similar abilities have equal access to office". An example was given that if two persons X and Y have identical talent, but X is from a poor family while Y is from a rich one, then equality of fair opportunity is in effect when both X and Y have the same chance of winning the job. It suggests the ideal society is "classless" without a social hierarchy being passed from generation to generation, although parents can still pass along advantages to their children by genetics and socialization skills. One view suggests that this approach might advocate "invasive interference in family life". Marshall posed this question:

Does it demand that, however unequal their abilities, people should be equally empowered to achieve their goals? This would imply that the unmusical individual who wants to be a concert pianist should receive more training than the child prodigy.

Economist Paul Krugman agrees mostly with the Rawlsian approach in that he would like to "create the society each of us would want if we didn't know in advance who we'd be". Krugman elaborated: "If you admit that life is unfair, and that there's only so much you can do about that at the starting line, then you can try to ameliorate the consequences of that unfairness".

Level playing field
The match's outcome is deemed legitimate if there is a level playing field and rules do not favor either player or team arbitrarily. (photo: Cesc Fàbregas duels with Anderson in a football match in 2008)

Some theorists have posed a level playing field conception of equality of opportunity, similar in many respects to the substantive principle (although it has been used in different contexts to describe formal equality of opportunity) and it is a core idea regarding the subject of distributive justice espoused by John Roemer and Ronald Dworkin and others. Like the substantive notion, the level playing field conception goes farther than the usual formal approach. The idea is that initial "unchosen inequalities" – prior circumstances over which an individual had no control, but which impact his or her success in a given competition for a particular post – these unchosen inequalities should be eliminated as much as possible, according to this conception. According to Roemer, society should "do what it can to level the playing field so that all those with relevant potential will eventually be admissible to pools of candidates competing for positions". Afterwards, when an individual competes for a specific post, he or she might make specific choices which cause future inequalities – and these inequalities are deemed acceptable because of the previous presumption of fairness. This system helps undergird the legitimacy of a society's divvying up of roles as a result in the sense that it makes certain achieved inequalities "morally acceptable", according to persons who advocate this approach.[2] This conception has been contrasted to the substantive version among some thinkers and it usually has ramifications for how society treats young persons in such areas as education and socialization and health care, but this conception has been criticized as well. John Rawls postulated the difference principle which argued that "inequalities are justified only if needed to improve the lot of the worst off, for example by giving the talented an incentive to create wealth".

Moral senses

There is general agreement that equality of opportunity is good for society, although there are diverse views about how it is good since it is a value judgement. It is generally viewed as a positive political ideal in the abstract sense. In nations where equality of opportunity is absent, it can negatively impact economic growth, according to some views and one report in Al Jazeera suggested that Egypt, Tunisia and other Middle Eastern nations were stagnating economically in part because of a dearth of equal opportunity.

Practical considerations

Difficulties with implementation

There is general agreement that programs to bring about certain types of equality of opportunity can be difficult and that efforts to cause one result often have unintended consequences or cause other problems.

A government policy that requires equal treatment can pose problems for lawmakers. A requirement for the government to provide equal health care services for all citizens can be prohibitively expensive.  If the government seeks equality of opportunity for citizens to get health care by rationing services using a maximization model to try to save money, new difficulties might emerge. For example, trying to ration health care by maximizing the "quality-adjusted years of life" might steer monies away from disabled persons even though they may be more deserving, according to one analysis. In another instance, BBC News questioned whether it was wise to ask female army recruits to undergo the same strenuous tests as their male counterparts since many women were being injured as a result.

Age discrimination can present vexing challenges for policymakers trying to implement equal opportunity. According to several studies, attempts to be equally fair to both a young and an old person are problematic because the older person has presumably fewer years left to live and it may make more sense for a society to invest greater resources in a younger person's health. Treating both persons equally while following the letter of the equality of opportunity seems unfair from a different perspective.

Efforts to achieve equal opportunity along one dimension can exacerbate unfairness in other dimensions.  For example, public bathrooms: If for the sake of fairness the physical area of men's and women's bathrooms is equal, the overall result may be unfair since men can use urinals, which require less physical space. In other words, a more fair arrangement may be to allot more physical space for women's restrooms. The sociologist Harvey Molotch explained: "By creating men's and women's rooms of the same size, society guarantees that individual women will be worse off than individual men."

Another difficulty is that it is hard for a society to bring substantive equality of opportunity to every type of position or industry. If a nation focuses efforts on some industries or positions, then people with other talents may be left out. For example, in an example in the Stanford Encyclopedia of Philosophy, a warrior society might provide equal opportunity for all kinds of people to achieve military success through fair competition, but people with non-military skills such as farming may be left out.

Lawmakers have run into problems trying to implement equality of opportunity. In 2010 in Britain, a legal requirement "forcing public bodies to try to reduce inequalities caused by class disadvantage" was scrapped after much debate and replaced by a hope that organizations would try to focus more on "fairness" than "equality" as fairness is generally seen as a much unclear concept than equality, but easier for politicians to manage if they are seeking to avoid fractious debate. In New York City, mayor Ed Koch tried to find ways to maintain the "principle of equal treatment" while arguing against more substantive and abrupt transfer payments called minority set-asides.

Cultural diversity of lifestyles, value systems, traditions, and beliefs can explain differences in outcomes between subgroups.

Measures

Many economists measure the degree of equal opportunity with measures of economic mobility. For instance, Joseph Stiglitz asserts that with five economic divisions and full equality of opportunity, "20 percent of those in the bottom fifth would see their children in the bottom fifth. Denmark almost achieves that – 25 percent are stuck there. Britain, supposedly notorious for its class divisions, does only a little worse (30 percent). That means they have a 70 percent chance of moving up. The chances of moving up in America, though, are markedly smaller (only 58 percent of children born to the bottom group make it out), and when they do move up, they tend to move up only a little". Similar analyses can be performed for each economic division and overall. They all show how far from the ideal all industrialized nations are and how correlated measures of equal opportunity are with income inequality and wealth inequality. Equal opportunity has ramifications beyond income; the American Human Development Index, rooted in the capabilities approach pioneered by Amartya Sen, is used to measure opportunity across geographies in the U.S. using health, education, and standard of living outcomes.

There is little income mobility – the notion of America as a land of opportunity is a myth.

— Joseph E. Stiglitz, 2012

Difficulties with measurement

The consensus view is that trying to measure equality of opportunity is difficult whether examining a single hiring decision or looking at groups over time.

  • Single instance. It is possible to reexamine the procedures governing a specific hiring decision, see if they were followed, and re-evaluate the selection by asking questions such as "Was it fair? Were fair procedures followed? Was the best applicant selected?". This is a judgment call and biases may enter into the minds of decision-makers. The determination of equality of opportunity in such an instance is based on mathematical probability: if equality of opportunity is in effect, then it is seen as fair if each of two applicants has a 50 percent chance of winning the job, that is, they both have equal chances to succeed (assuming of course that the person making the probability assessment is unaware of all variables – including valid ones such as talent or skill as well as arbitrary ones such as race or gender). However, it is hard to measure whether each applicant had a 50 percent chance based on the outcome.
  • Groups. When assessing the equal opportunity for a type of job or company or industry or nation, then statistical analysis is often done by looking at patterns and abnormalities, typically comparing subgroups with larger groups on a percentage basis. Averaging opportunities over subgroups allows to determine if there are statistically significant differences in outcomes between subgroups. For factors where blinded experiments are feasible, the equality or lack of equality of opportunity due to this factor can be determined up to statistical significance. While substantive equality for group outcomes can be measured by comparing statistically significant differences in subgroup outcomes, formal equality of opportunities does not require equal outcomes between groups. If equality of opportunity is violated, perhaps by discrimination which affects a subgroup or population over time, it is possible to make this determination using statistical analysis, but there are numerous difficulties involved. Nevertheless, entities such as city governments and universities have hired full-time professionals with knowledge of statistics to ensure compliance with equal opportunity regulations. For example, Colorado State University requires the director of its Office of Equal Opportunity to maintain extensive statistics on its employees by job category as well as minorities and gender. In Britain, Aberystwyth University collects information including the "representation of women, men, members of racial or ethnic minorities and people with disabilities amongst applicants for posts, candidates interviewed, new appointments, current staff, promotions and holders of discretionary awards" to comply with equal opportunity laws.

It is difficult to prove unequal treatment although statistical analysis can provide indications of problems, it is subject to conflicts over interpretation and methodological issues. For example, a study in 2007 by the University of Washington examined its treatment of women. Researchers collected statistics about female participation in numerous aspects of university life, including percentages of women with full professorships (23 percent), enrollment in programs such as nursing (90 percent), engineering (18 percent). There is wide variation in how these statistics might be interpreted. For example, the 23 percent figure for women with full professorships could be compared to the total population of women (presumably 50 percent) perhaps using census data, or it might be compared to the percentage of women with full professorships at competing universities. It might be used in an analysis of how many women applied for the position of full professor compared to how many women attained this position. Further, the 23 percent figure could be used as a benchmark or baseline figure as part of an ongoing longitudinal analysis to be compared with future surveys to track progress over time. In addition, the strength of the conclusions is subject to statistical issues such as sample size and bias. For reasons such as these, there is considerable difficulty with most forms of statistical interpretation.

Statistical analysis of equal opportunity has been done using sophisticated examinations of computer databases. An analysis in 2011 by University of Chicago researcher Stefano Allesina examined 61,000 names of Italian professors by looking at the "frequency of last names", doing one million random drawings and he suggested that Italian academia was characterized by violations of equal opportunity practices as a result of these investigations. The last names of Italian professors tended to be similar more often than predicted by random chance. The study suggested that newspaper accounts showing that "nine relatives from three generations of a single-family (were) on the economics faculty" at the University of Bari were not aberrations, but indicated a pattern of nepotism throughout Italian academia.

Substative equality is typically measured by the criteria of equality of outcome for groups, although with difficulty. In one example, an analysis of relative equality of opportunity was done based on outcomes, such as a case to see whether hiring decisions were fair regarding men versus women – the analysis was done using statistics based on average salaries for different groups. In another instance, a cross-sectional statistical analysis was conducted to see whether social class affected participation in the United States Armed Forces during the Vietnam War: a report in Time by the Massachusetts Institute of Technology suggested that soldiers came from a variety of social classes and that the principle of equal opportunity had worked, possibly because soldiers had been chosen by a lottery process for conscription. In college admissions, equality of outcome can be measured directly by comparing offers of admission given to different groups of applicants: for example, there have been reports in newspapers of discrimination against Asian Americans regarding college admissions in the United States which suggest that Asian American applicants need higher grades and test scores to win admission to prestigious universities than other ethnic groups.

Marketplace considerations

Equal opportunity of opportunity has been described as a fundamental basic notion in business and commerce and described by economist Adam Smith as a basic economic precept. There has been research suggesting that "competitive markets will tend to drive out such discrimination" since employers or institutions which hire based on arbitrary criteria will be weaker as a result and not perform as well as firms that embrace equality of opportunity. Firms competing for overseas contracts have sometimes argued in the press for equal chances during the bidding process, such as when American oil corporations wanted equal shots at developing oil fields in Sumatra; and firms, seeing how fairness is beneficial while competing for contracts, can apply the lesson to other areas such as internal hiring and promotion decisions. A report in USA Today suggested that the goal of equal opportunity was "being achieved throughout most of the business and government labor markets because major employers pay based on potential and actual productivity".

Fair opportunity practices include measures taken by an organization to ensure efficiency effectiveness and fairness in the employment process. A basic definition of equality is the idea of equal treatment and respect. In job advertisements and descriptions, the fact that the employer is an equal opportunity employer is sometimes indicated by the abbreviations EOE or MFDV, which stands for Minority, Female, Disabled, Veteran. Analyst Ross Douthat in The New York Times suggested that equality of opportunity depends on a rising economy which brings new chances for upward mobility and he suggested that greater equality of opportunity is more easily achieved during "times of plenty". Efforts to achieve equal opportunity can rise and recede, sometimes as a result of economic conditions or political choices. Empirical evidence from public health research also suggests that equality of opportunity is linked to better health outcomes in the United States and Europe.

History

According to professor David Christian of Macquarie University, an underlying Big History trend has been a shift from seeing people as resources to exploiting towards a perspective of seeing people as individuals to empower. According to Christian, in many ancient agrarian civilizations, roughly nine of every ten persons was a peasant exploited by a ruling class. In the past thousand years, there has been a gradual movement in the direction of greater respect for equal opportunity as political structures based on generational hierarchies and feudalism broke down during the late Middle Ages and new structures emerged during the Renaissance. Monarchies were replaced by democracies: kings were replaced by parliaments and congresses. Slavery was also abolished generally. The new entity of the nation state emerged with highly specialized parts, including corporations, laws, and new ideas about citizenship as well as values about individual rights found expression in constitutions, laws, and statutes.

African-American civil rights lawyer Thurgood Marshall fought numerous battles in the courts for equal opportunity for all races in the United States; argued the 1954 Brown v. Board of Education case and won, and in 1967 was appointed to the Supreme Court.

In the United States, one legal analyst suggested that the real beginning of the modern sense of equal opportunity was in the Fourteenth Amendment which provided "equal protection under the law". The amendment did not mention equal opportunity directly, but it helped undergird a series of later rulings which dealt with legal struggles, particularly by African Americans and later women, seeking greater political and economic power in the growing republic. In 1933, a congressional "Unemployment Relief Act" forbade discrimination "based on race, color, or creed". The Supreme Court's 1954 Brown v. Board of Education decision furthered government initiatives to end discrimination.

In 1961, President John F. Kennedy signed Executive Order 10925 which enabled a presidential committee on an equal opportunity, which was soon followed by President Lyndon B. Johnson's Executive Order 11246. The Civil Rights Act of 1964 became the legal underpinning of equal opportunity in employment. Businesses and other organizations learned to comply with the rulings by specifying fair hiring and promoting practices and posting these policy notices on bulletin boards, employee handbooks, and manuals as well ain s training sessions and films. Courts dealt with issues about equal opportunities, such as the 1989 Wards Cove decision, the Supreme Court ruled that statistical evidence by itself was insufficient to prove racial discrimination. The Equal Employment Opportunity Commission was established, sometimes reviewing charges of discrimination cases which numbered in the tens of thousands annually during the 1990s. Some law practices specialized in employment law. The conflict between formal and substantive approaches manifested itself in backlashes, sometimes described as reverse discrimination, such as the Bakke case when a white male applicant to medical school sued based on being denied admission because of a quota system preferring minority applicants. In 1990, the Americans with Disabilities Act prohibited discrimination against disabled persons, including cases of equal opportunity. In 2008, the Genetic Information Nondiscrimination Act prevents employers from using genetic information when hiring, firing, or promoting employees.

Equal opportunity issues are discussed at an army roundtable in Alabama.

Many countries have specific bodies tasked with looking at equality of opportunity issues. In the United States, for example, it is the Equal Employment Opportunity Commission; in Britain, there is the Equality of Opportunity Committee[24] as well as the Equality and Human Rights Commission; in Canada, the Royal Commission on the Status of Women has "equal opportunity as its precept"; and in China, the Equal Opportunities Commission handles matters regarding ethnic prejudice. In addition, there have been political movements pushing for equal treatment, such as the Women's Equal Opportunity League which in the early decades of the twentieth century, pushed for fair treatment by employers in the United States. One of the group's members explained:

I am not asking for sympathy but for an equal right with men to earn my own living in the best way open and under the most favorable conditions that I could choose for myself.

Global initiatives such as the United Nations Sustainable Development Goal 5 and Goal 10 are also aimed at ensuring equal opportunities for women at all levels of decision making, and reducing inequalities of outcome.

Criticism

There is agreement that the concept of equal opportunity lacks a precise definition. While it generally describes "open and fair competition" with equal chances for achieving sought-after jobs or positions as well as an absence of discrimination, the concept is elusive with a "wide range of meanings". Formal equality is hard to measure, and implementation of substantive equality poses problems as well as disagreements about what to do.

There have been various criticisms directed at both the substantive and formal approaches. One account suggests that left-leaning thinkers who advocate equality of outcome fault even formal equality of opportunity because it "legitimates inequalities of wealth and income". John W. Gardner suggested several views: (1) that inequalities will always exist regardless of trying to erase them; (2) that bringing everyone "fairly to the starting line" fails to deal with the "destructive competitiveness that follows"; (3) that any equalities achieved will entail future inequalities. Substantive equality of opportunity has led to concerns that efforts to improve fairness "ultimately collapses into the different one of equality of outcome or condition".

Economist Larry Summers advocated an approach of focusing on equality of opportunity and not equality of outcomes and that the way to strengthen equal opportunity was to bolster public education. A contrasting report in The Economist criticized efforts to contrast equality of opportunity and equality of outcome as being opposite poles on a hypothetical ethical scale, such that equality of opportunity should be the "highest ideal" while equality of outcome was "evil". Rather, the report argued that any difference between the two types of equality was illusory and that both terms were highly interconnected. According to this argument, wealthier people have greater opportunities – wealth itself can be considered as "distilled opportunity" – and children of wealthier parents have access to better schools, health care, nutrition and so forth. Accordingly, people who endorse equality of opportunity may like the idea of it in principle, yet at the same time, they would be unwilling to take the extreme steps or "titanic interventions" necessary to achieve real intergenerational equality. A slightly different view in The Guardian suggested that equality of opportunity was merely a "buzzword" to sidestep the thornier political question of income inequality.

There is speculation that since equality of opportunity is only one of sometimes competing "justice norms", there is a risk that following equality of opportunity too strictly might cause problems in other areas. A hypothetical example was suggested: suppose wealthier people gave excessive amounts of campaign contributions; suppose further that these contributions resulted in better regulations, and then laws limiting such contributions based on equal opportunity for all political participants may have the unintended long term consequence of making political decision-making lackluster and possibly hurting the groups that it was trying to protect. Philosopher John Kekes makes a similar point in his book The Art of Politics in which he suggests that there is a danger to elevating any one particular political good – including equality of opportunity – without balancing competing goods such as justice, property rights and others. Kekes advocated having a balanced perspective, including a continuing dialog between cautionary elements and reform elements. A similar view was expressed by Ronald Dworkin in The Economist:

It strikes us as wrong – or not right – that some people starve while others have private jets. We are uncomfortable when university professors earn less, for example than junior lawyers. But equality appears to pull against other important ideals such as liberty and efficiency.

Economist Paul Krugman sees equality of opportunity as a "non-Utopian compromise" which works and is a "pretty decent arrangement" which varies from country to country. However, there are differing views such as by Matt Cavanagh, who criticised equality of opportunity in his 2002 book Against Equality of Opportunity. Cavanagh favored a limited approach of opposing specific kinds of discrimination as steps to help people get greater control over their lives.

Conservative thinker Dinesh D'Souza criticized equality of opportunity on the basis that "it is an ideal that cannot and should not be realized through the actions of the government" and added that "for the state to enforce equal opportunity would be to contravene the true meaning of the Declaration and to subvert the principle of a free society". D'Souza described how his parenting undermined equality of opportunity:

I have a five-year-old daughter. Since she was born ... my wife and I have gone to great lengths in the Great Yuppie Parenting Race. ... My wife goes over her workbooks. I am teaching her chess. Why are we doing these things? We are, of course, trying to develop her abilities so that she can get the most out of life. The practical effect of our actions, however, is that we are working to give our daughter an edge – that is, a better chance to succeed than everybody else's children. Even though we might be embarrassed to think of it this way, we are doing our utmost to undermine equal opportunity. So are all the other parents who are trying to get their children into the best schools

Equal opportunity theorists generally agree that once the race begins, who wins is a function of talent, hard work, and competitive drive. (photo: runner Billy Mills crossing the finish line in the 1964 Olympics)

D'Souza argued that it was wrong for the government to try to bring his daughter down, or to force him to raise other people's children, but a counterargument is that there is a benefit to everybody, including D'Souza's daughter, to have a society with less anxiety about downward mobility, less class resentment, and less possible violence.

An argument similar to D'Souza's was raised in Anarchy, State, and Utopia by Robert Nozick, who wrote that the only way to achieve equality of opportunity was "directly worsening the situations of those more favored with opportunity, or by improving the situation of those less well-favored". Nozick gave an argument of two suitors competing to marry one "fair lady": X was plain while Y was better looking and more intelligent. If Y did not exist, then "fair lady" would have married X, but Y exists and so she marries Y. Nozick asks: "Does suitor X have a legitimate complaint against Y based on unfairness since Y did not earn his good looks or intelligence?". Nozick suggests that there are no grounds for complaint. Nozick argued against equality of opportunity because it violates the rights of property since the equal opportunity maxim interferes with an owner's right to do what he or she pleases with a property.

Property rights were a major component of the philosophy of John Locke and are sometimes referred to as "Lockean rights". The sense of the argument is along these lines: equal opportunity rules regarding, say, a hiring decision within a factory, made to bring about greater fairness, violate a factory owner's rights to run the factory as he or she sees best; it has been argued that a factory owner's right to property encompasses all decision-making within the factory as being part of those property rights. That some people's "natural assets" were unearned is irrelevant to the equation according to Nozick and he argued that people are nevertheless entitled to enjoy these assets and other things freely given by others.

Friedrich Hayek felt that luck was too much of a variable in economics, such that one can not devise a system with any kind of fairness when many market outcomes are unintended. By sheer chance or random circumstances, a person may become wealthy just by being in the right place and time and Hayek argued that it is impossible to devise a system to make opportunities equal without knowing how such interactions may play out. Hayek saw not only equality of opportunity, but all of social justice as a "mirage".

Some conceptions of equality of opportunity, particularly the substantive and level playing field variants, have been criticized on the basis that they make assumptions to the effect that people have similar genetic makeups. Other critics have suggested that social justice is more complex than mere equality of opportunity. Nozick made the point that what happens in society can not always be reduced to competition for a coveted position and in 1974 wrote that "life is not a race in which we all compete for a prize which someone has established", that there is "no unified race" and there is not someone person "judging swiftness".

To each according to his contribution

To each according to his contribution" is a principle of distribution considered to be one of the defining features of socialism. It refers to an arrangement whereby individual compensation is representative of one's contribution to the social product (total output of the economy) in terms of effort, labor and productivity. This is in contrast to the method of distribution and compensation in capitalism, an economic and political system in which property owners can receive income by virtue of ownership irrespective of their contribution to the social product.

The concept formed the basic definition of socialism for its pre-Marxist proponents, including Ricardian socialists, classical economists, collectivist anarchists and individualist anarchists, as well as for Marx, who contrasted it with "to each according to his need" as the corresponding principle of completed communism.

Definition and purpose

To each according to his contribution was a concept espoused by many members of the socialist and labor movement. The French socialist Saint-Simonists of the 1820s and 1830s used slogans such as, "from each according to his ability, to each ability according to its work" or, "From each according to his capacity, to each according to his works.” Other examples of this can be found from Ferdinand Lassalle's and Eugen Dühring's statements to Leon Trotsky's writings. Vladimir Lenin, inspired by Marx's writing on the subject in his Critique of the Gotha Programme, claimed the principle to be a fundamental element of socialism within Marxist theory.

Libertarian socialist thinkers, such as American anarchist Benjamin Tucker, defined socialism as a system whereby the laborer receives the full product of his labor through the elimination of exploitation and accrual of unearned income to a capitalist class.

The term means simply that each worker in a socialist society receives compensation and benefits according to the quantity and value of the labor that they contributed. This translates into workers of great productivity receiving more wages and benefits than workers of average productivity, and substantially more than workers of lesser productivity. An extension of this principle could also be made so that the more difficult one's job is – whether this difficulty is derived from greater training requirements, job intensity, safety hazards, etc. – the more one is rewarded for the labor contributed. The purpose of the principle, as Trotsky would later state, is to promote productivity. This is done by creating incentives to work harder, longer, and more productively. The principle is ultimately a stowaway from capitalism that, according to Marx, will vanish as work becomes more automated and enjoyable, and goods become available in abundance.

Elaboration by Marx

Capitalism can lead to a situation where the means of production are owned by a small minority who do not produce, but rather live off the labor of others. Socialism is said to remedy this by putting the means of production in common hands and rewarding individuals according to their contributions.

In the Critique of the Gotha Programme, while criticizing Ferdinand Lassalle's ideas, Marx elaborates on the theory. According to Marx's analysis of the Programme, Lassalle suggests that "the proceeds of labor belong undiminished with equal right to all members of society". While agreeing that the citizens of a workers' society should be rewarded according to individual contributions, Marx claims that giving them the "full product" of their labor is impossible as some of the proceeds will be needed to maintain infrastructure and so forth. He then explains the nature of a communist society in its transition phase (socialist society), which does not emerge from its own foundations "but, on the contrary, .. from capitalist society; [and] thus in every respect, economically, morally, and intellectually, still stamped with the birthmarks of the old society from whose womb it emerges". And so, "accordingly, the individual producer receives back from society – after the deductions have been made – exactly what he gives to it". He explains this as:

What he has given to it is his individual quantum of labor. For example, the social working day consists of the sum of the individual hours of work; the individual labor time of the individual producer is the part of the social working day contributed by him, his share in it. He receives a certificate from society that he has furnished such-and-such an amount of labor (after deducting his labor for the common funds); and with this certificate, he draws from the social stock of means of consumption as much as the same amount of labor cost. The same amount of labor which he has given to society in one form, he receives back in another.

In the paragraph immediately following, Marx continues to explain how this system of exchange is related to the capitalist system of exchange:

Here, obviously, the same principle prevails as that which regulates the exchange of commodities, as far as this is exchange of equal values. Content and form are changed, because under the altered circumstances no one can give anything except his labor, and because, on the other hand, nothing can pass to the ownership of individuals, except individual means of consumption. But as far as the distribution of the latter among the individual producers is concerned, the same principle prevails as in the exchange of commodity equivalents: a given amount of labor in one form is exchanged for an equal amount of labor in another form.

Marx says that this is rational and necessary, and that once society advances from the early phase of communist society and work becomes life's prime want, distribution will occur differently. During the completed phase of communism, the standard shall be "from each according to his ability, to each according to his needs".

The Leninist view

Lenin wrote The State and Revolution to inform the public and to prevent Marxism from becoming tainted by "opportunists" and "reformists", as he called them. The work is very important as it categorizes the "first phase of communist society" as socialism, with the completed phase being communism proper. The pamphlet also answers many questions and concerns of the Marxists of his time by utilizing the classic works of Marxism.

When he is set to describe socialism and its economic features he turns to the authority of Marx, especially the Critique of the Gotha Programme. Lenin claims that socialism will not be perfect since, as Marx said, it has emerged from the womb of capitalism and which is in every respect stamped with the birthmarks of the old society. This society, socialism, will be unable to provide people with total equality, precisely because it is still marked by capitalism. He also explains the difference between the old society and the new as:

The means of production are no longer the private property of individuals. The means of production belong to the whole of society. Every member of society, performing a certain part of the socially-necessary work, receives a certificate from society to the effect that he has done a certain amount of work. And with this certificate he receives from the public store of consumer goods a corresponding quantity of products. After a deduction is made of the amount of labor which goes to the public fund, every worker, therefore, receives from society as much as he has given to it.

Lenin states that such a society is indeed socialism as it realizes the two principles of socialism "he who does not work, neither shall he eat" and "an equal amount of products for an equal amount of labor".

Joseph Stalin and Leon Trotsky both mentioned the term in their works.

  • Stalin's most famous use of the concept is in his 1936 Soviet Constitution. He writes that "The principle applied in the U.S.S.R. is that of socialism: From each according to his ability, to each according to his work."
  • Trotsky's mention is in his famous The Revolution Betrayed. He says that "Capitalism prepared the conditions and forces for a social revolution: technique, science and the proletariat. The communist structure cannot, however, immediately replace the bourgeois society. The material and cultural inheritance from the past is wholly inadequate for that." He goes on to defend his position by saying that "in its first steps the workers’ state cannot yet permit everyone to work "according to his abilities" – that is, as much as he can and wishes to – nor can it reward everyone "according to his needs", regardless of the work he does." And he presents the principle as the method that socialism will use by saying: "In order to increase the productive forces, it is necessary to resort to the customary norms of wage payment – that is, to the distribution of life's goods in proportion to the quantity and quality of individual labor."

Social parasitism (offense)

Social parasitism was considered a political crime in the Soviet Union, where individuals accused of living off the efforts of others or society were prosecuted. The Soviet Union, proclaiming itself a workers' state, mandated that every capable adult engage in work until retirement, theoretically eliminating unemployment.

Soviet Union

Russian poet Joseph Brodsky (1940–1996) was sentenced in 1964 to five years of hard labor in Arkhangelsk Oblast for "social parasitism".

In the Soviet Union, which declared itself a workers' state, every adult able-bodied person was expected to work until official retirement. Thus unemployment was officially and theoretically eliminated. Those who refused to work, study or serve in another way risked being criminally charged with social parasitism (Russian: тунеядство tuneyadstvo, тунеядцы [tuneyadets/tuneyadtsy"), in accordance with the socialist principle "from each according to his ability, to each according to his contribution."

On 4 May 1961 the law "On Intensification of the Struggle against Persons who avoid Socially Useful Work and lead an Anti-social Parasitic Way of Life" which criminalised parasitism entered into force. Those who refused to work were critiqued as "able-bodied citizens who refuse to fulfil their important constitutional duty - to perform honest work to the best of their ability".

In 1961, 130,000 people were identified as leading the "anti-social, parasitic way of life" in the Russian Soviet Federative Socialist Republic. Charges of parasitism were frequently applied to the homeless, vagrants, beggars, dissidents and refuseniks, many of whom were intellectuals. Since their writings were considered anti-establishment, the state prevented them from obtaining employment. To avoid trials for parasitism, many of them took unskilled (but not especially time-consuming) jobs (street sweepers, boiler room attendants, etc.), which allowed them to continue their other pursuits.

For example, the Russian poet Joseph Brodsky was charged with social parasitism by the Soviet authorities. A 1964 trial found that his series of odd jobs and role as a poet were not a sufficient contribution to society.

A number of Soviet intellectuals and dissidents were accused of the crime of parasitism, including Iosif Begun, Vladimir Voinovich, Lev Kopelev and Andrei Amalrik.

Belarus

On 2 April 2015 President Alexander Lukashenko issued a decree 'On Prevention of Social Dependency', which included a tax for those categorised "social parasites". Lukashenko said the policy was brought in to respond to the half a million citizens who refused to work. The decree said the policy's purpose was "to prevent freeloading, encourage employment among able-bodied citizens, and to ensure the compliance with the constitutional obligation of the citizens to participate in the financing of state expenditures". Individuals exempt from the policy were students, minors, disabled people, retirees, prisoners, and parents with children below the age of seven or those with three or more children who were minors.

Defined as people working under 183 days in a year, and excluding home-makers and subsistence farmers, the deployment of the so-called parasite tax was suspended after protests in several major urban centers.

Hungary

Social parasitism (direct translation from Hungarian: Publicly menace work evasion-Közveszélyes munkakerülés, abbreviated: KMK) was a criminal offense prosecuted by the 20th century's Hungarian legal system, which was part of the law in force between 1913 and 1989.

In the early 1900s, the need arose to address the situation of the unemployed, unwilling to work, begging, and vagrant masses: the institution of workhouses was considered more effective than the institution of workhouses. Workhouses – where the daily working time was ten hours – were established in a separate part of prisons; for men, the Jászberény Royal District Court Prison was designated, and for women, the Kalocsa Royal Court Prison was designated. According to Article XXI of 1913 on Publicly menace work evasion: "A person of working age who is referred to the court and who shuns work or otherwise engages in a work-avoiding lifestyle shall be punished by imprisonment for a term of eight days to two months for an offence." The same law criminalized illegal gambling and the plying of prostitutes/sex work as work-avoiding that is dangerous to the public. Foreigners could also be expelled from the country if they were classified as work-avoiding that is menace to the public. After the Communist took over in Hungary, they re-established this article especially because they had shortage of workers. Publicly menace evasion of work was a legally punishable offense or misdemeanor, and its prosecution was an important police task. "Its perpetrators endanger public safety and public order. Those who do not work through no fault of their own usually become criminals, because there is hardly any other way to satisfy their basic life needs (support, profit, inheritance, etc.)."

The Penal Code adopted in 1978(38§) provided for the following regarding evasion: "A person capable of working who engages in a work-avoiding lifestyle, if he has previously been punished for a public-menace work-avoiding offense or violation of the law and two years have not yet passed since the sentence was served or its enforceability ceased, commits a misdemeanor and is punishable by imprisonment for up to one year, corrective labor, or a fine. As an additional punishment, disqualification is also possible."

Under the Kádár regime(1956-1988), 2–300 people were convicted annually for work evasion menace to the public, and over 2,000 were sentenced to misdemeanor detention. Legislative Decree 19 of 1984 introduced stricter correctional labor in order to “accustom work” to regular work. Subsequently, the number of so-called work evasion offenders sentenced by court judgment increased to over 2,000.

Work evasion that was dangerous to the public has not been a criminal offense since Act XXIII of 1989 came into force

Romania

Romanian prostitute, convicted of social parasitism in Constanța, 1970.

Nicolae Ceaușescu, president of the Socialist Republic of Romania, criminalized social parasitism by decree in 1970. The regime viewed young people as potentially destabilizing and targeted those who did not fit into socialist norms. Citizens could be stopped if they were found on the street during hours when they should have been at work or school. Penalties were imprisonment for one to six months, or a fine of 1,000 to 5,000 lei. Indecent or obscene gestures or words carried penalties of 20 days to three months in prison, or a fine of up to 2,000 lei.

A 1976 law broadened the campaign against parasitism. It stated that if someone able to work refused a job, he could be forced by court order to work for one year on construction sites, farms, in forests, or factories. The Miliția was tasked with enforcing the measures, and its actions were often arbitrary.

Cognitive computer

From Wikipedia, the free encyclopedia
https://en.wikipedia.org/wiki/Cognitive_computer

A cognitive computer is a computer that hardwires artificial intelligence and machine learning algorithms into an integrated circuit that closely reproduces the behavior of the human brain. It generally adopts a neuromorphic engineering approach. Synonyms include neuromorphic chip and cognitive chip.

In 2023, IBM's proof-of-concept NorthPole chip (optimized for 2-, 4- and 8-bit precision) achieved remarkable performance in image recognition.

In 2013, IBM developed Watson, a cognitive computer that uses neural networks and deep learning techniques. The following year, it developed the 2014 TrueNorth microchip architecture which is designed to be closer in structure to the human brain than the von Neumann architecture used in conventional computers. In 2017, Intel also announced its version of a cognitive chip in "Loihi, which it intended to be available to university and research labs in 2018. Intel (most notably with its Pohoiki Beach and Springs systems), Qualcomm, and others are improving neuromorphic processors steadily.

IBM TrueNorth chip

DARPA SyNAPSE board with 16 TrueNorth chips

TrueNorth was a neuromorphic CMOS integrated circuit produced by IBM in 2014. It is a manycore processor network on a chip design, with 4096 cores, each one having 256 programmable simulated neurons for a total of just over a million neurons. In turn, each neuron has 256 programmable "synapses" that convey the signals between them. Hence, the total number of programmable synapses is just over 268 million (228). Its basic transistor count is 5.4 billion.

Details

Memory, computation, and communication are handled in each of the 4096 neurosynaptic cores, TrueNorth circumvents the von Neumann-architecture bottleneck and is very energy-efficient, with IBM claiming a power consumption of 70 milliwatts and a power density that is 1/10,000th of conventional microprocessors. The SyNAPSE chip operates at lower temperatures and power because it only draws power necessary for computation. Skyrmions have been proposed as models of the synapse on a chip.

The neurons are emulated using a Linear-Leak Integrate-and-Fire (LLIF) model, a simplification of the leaky integrate-and-fire model.

According to IBM, it does not have a clock, operates on unary numbers, and computes by counting to a maximum of 19 bits. The cores are event-driven by using both synchronous and asynchronous logic, and are interconnected through an asynchronous packet-switched mesh network on chip (NOC).

IBM developed a new network to program and use TrueNorth. It included a simulator, a new programming language, an integrated programming environment, and libraries. This lack of backward compatibility with any previous technology (e.g., C++ compilers) poses serious vendor lock-in risks and other adverse consequences that may prevent it from commercialization in the future.

Research

In 2018, a cluster of TrueNorth network-linked to a master computer was used in stereo vision research that attempted to extract the depth of rapidly moving objects in a scene.

IBM NorthPole chip

In 2023, IBM released its NorthPole chip, which is a proof-of-concept for dramatically improving performance by intertwining compute with memory on-chip, thus eliminating the Von Neumann bottleneck. It blends approaches from IBM's 2014 TrueNorth system with modern hardware designs to achieve speeds about 4,000 times faster than TrueNorth. It can run ResNet-50 or Yolo-v4 image recognition tasks about 22 times faster, with 25 times less energy and 5 times less space, when compared to GPUs which use the same 12-nm node process that it was fabricated with. It includes 224 MB of RAM and 256 processor cores and can perform 2,048 operations per core per cycle at 8-bit precision, and 8,192 operations at 2-bit precision. It runs at between 25 and 425 MHz. This is an inferencing chip, but it cannot yet handle GPT-4 because of memory and accuracy limitations

Intel Loihi chip

Pohoiki Springs

Pohoiki Springs is a system that incorporates Intel's self-learning neuromorphic chip, named Loihi, introduced in 2017, perhaps named after the Hawaiian seamount Lōʻihi. Intel claims Loihi is about 1000 times more energy efficient than general-purpose computing systems used to train neural networks. In theory, Loihi supports both machine learning training and inference on the same silicon independently of a cloud connection, and more efficiently than convolutional neural networks or deep learning neural networks. Intel points to a system for monitoring a person's heartbeat, taking readings after events such as exercise or eating, and using the chip to normalize the data and work out the ‘normal’ heartbeat. It can then spot abnormalities and deal with new events or conditions.

The first iteration of the chip was made using Intel's 14 nm fabrication process and houses 128 clusters of 1,024 artificial neurons each for a total of 131,072 simulated neurons. This offers around 130 million synapses, far less than the human brain's 800 trillion synapses, and behind IBM's TrueNorth. Loihi is available for research purposes among more than 40 academic research groups as a USB form factor.

In October 2019, researchers from Rutgers University published a research paper to demonstrate the energy efficiency of Intel's Loihi in solving simultaneous localization and mapping.

In March 2020, Intel and Cornell University published a research paper to demonstrate the ability of Intel's Loihi to recognize different hazardous materials, which could eventually aid to "diagnose diseases, detect weapons and explosives, find narcotics, and spot signs of smoke and carbon monoxide".

Pohoiki Beach

Intel's Loihi 2, named Pohoiki Beach, was released in September 2021 with 64 cores. It boasts faster speeds, higher-bandwidth inter-chip communications for enhanced scalability, increased capacity per chip, a more compact size due to process scaling, and improved programmability.

Hala Point

Hala Point packages 1,152 Loihi 2 processors produced on Intel 3 process node in a six-rack-unit chassis. The system supports up to 1.15 billion neurons and 128 billion synapses distributed over 140,544 neuromorphic processing cores, consuming 2,600 watts of power. It includes over 2,300 embedded x86 processors for ancillary computations.

Intel claimed in 2024 that Hala Point was the world’s largest neuromorphic system. It uses Loihi 2 chips. It is claimed to offer 10x more neuron capacity and up to 12x higher performance.

Hala Point provides up to 20 quadrillion operations per second, (20 petaops), with efficiency exceeding 15 trillion (8-bit) operations S−1 W−1 on conventional deep neural networks.

Hala Point integrates processing, memory and communication channels in a massively parallelized fabric, providing 16 PB S−1 of memory bandwidth, 3.5 PB S−1 of inter-core communication bandwidth, and 5 TB S−1 of inter-chip bandwidth.

The system can process its 1.15 billion neurons 20 times faster than a human brain. Its neuron capacity is roughly equivalent to that of an owl brain or the cortex of a capuchin monkey.

Loihi-based systems can perform inference and optimization using 100 times less energy at speeds as much as 50 times faster than CPU/GPU architectures.

Intel claims that Hala Point can create LLMs but this has not been done. Much further research is needed.

SpiNNaker

SpiNNaker (Spiking Neural Network Architecture) is a massively parallel, manycore supercomputer architecture designed by the Advanced Processor Technologies Research Group at the Department of Computer Science, University of Manchester.

Criticism

Critics argue that a room-sized computer – as in the case of IBM's Watson – is not a viable alternative to a three-pound human brain. Some also cite the difficulty for a single system to bring so many elements together, such as the disparate sources of information as well as computing resources.

In 2021, The New York Times released Steve Lohr's article "What Ever Happened to IBM’s Watson?". He wrote about some costly failures of IBM Watson. One of them, a cancer-related project called the Oncology Expert Advisor, was abandoned in 2016 as a costly failure. During the collaboration, Watson could not use patient data. Watson struggled to decipher doctors’ notes and patient histories.

Environmental economics

From Wikipedia, the free encyclopedia
Growth, Development and Environmental Economics in Asia discussion at Chatham House, London

Environmental economics is a sub-field of economics concerned with environmental issues. It has become a widely studied subject due to growing environmental concerns in the twenty-first century. Environmental economics "undertakes theoretical or empirical studies of the economic effects of national or local environmental policies around the world. Particular issues include the costs and benefits of alternative environmental policies to deal with air pollution, water quality, toxic substances, solid waste, and global warming."

Environmental Versus Ecological Economics

Environmental economics is distinguished from ecological economics in that ecological economics emphasizes the economy as a subsystem of the ecosystem with its focus upon preserving natural capital. While environmental economics focuses on human preferences, by trying to balance protecting natural resources with people's needs for products and services. Due to these differences it can be seen that ecological economics takes a more holistic approach to traditional economic theories, while environmental economics fits within traditional economic theories.

One survey of German economists found that ecological and environmental economics are different schools of economic thought, with ecological economists emphasizing "strong" sustainability and rejecting the proposition that human-made ("physical") capital can substitute for natural capital.[5] And environmental economics focusing on the efficient allocation of natural resources in order to fulfill human wants.

History

18th and 19th Century

Although the term "environmental economics" became popular beginning in the 1960's, the entwinement of the two fields of environmentalism and economics started much earlier. Starting with economist Marquis de Condorcet in the 18th century, who had an interest in the link between economic activity and environmental issues. This was seen in his usage of externalities while analyzing environmental issues.

During the classical period of economics, Adam Smith realized while the market is able to allocate private goods efficiently for most goods, it fails to do so in some environmental circumstances. It is within these scenarios where the market fails, that the government needs to take action. This is seen in his quote "Erecting and maintaining certain public works and certain public institutions which it can never be for the interest of any individual, or small number of individuals to erect and maintain; because the profit would never repay the expense to any individual or small number of individuals, though it may frequently do much more than repay it to a great society." Thomas Robert Malthus also was another classical economist who's work led to the beginnings of environmental economists. Malthus' theory of population argued that agricultural productivity faces diminishing returns, which ultimately limits the exponential growth of human populations. This thought process later led economists to think about the relationship between resource scarcity and economic development. David Ricardo's writings connected the natural environment and the standard of living which further helped to develop environmental economics later on. He stressed that the value of land varies based on how fertile it is. The last classical economist to add to environmental economics was John Stuart Mill. In his Principles of Political Economy, he wrote that the management of the environment cannot be done by the market and individuals, and is instead a governmental obligation, "[I]s there not the earth itself, its forests and waters, and all other natural riches, above and below the surface? These are the inheritance of the human race, and there must be regulations for the common enjoyment of it. What rights, and under what conditions, a person shall be allowed to exercise over any portion of this common inheritance cannot be left undecided. No function of government is less optional than the regulation of these things, or more completely involved in the idea of civilized society."

20th Century

Environmental economics became increasingly more popular in the 19th century. This is when the Resources for the Future (RFF) was established in Washington, D.C. This independent research organization applied economics to environmental issues. During this time H. Scott Gordon released his paper "Economic Theory of a Common Property Resource: The Fishery" which claimed that open access fisheries can be exploited leading to economic rents to be dissipated. Another important paper adding to environmental economics at this time was "Spaceship Earth" by Kenneth E. Boulding. This paper describes the physical limits of earths resources and how technology cannot truly help humans push those limits. Finally, Ronald Coase created an economic solution to environmental issues, which solidified environmental economics as a sub field of economics. He believed that there were 2 solutions 1) to tax the creator of the polluter and to create regulation that put the burden of action on the polluter or 2) the sufferer must pay the polluter to not pollute.

Topics and concepts

Market failure

Air pollution is an example of market failure, as the factory is imposing a negative external cost on the community.

Central to environmental economics is the concept of market failure. Market failure means that markets fail to allocate resources efficiently. As stated by Hanley, Shogren, and White (2007): "A market failure occurs when the market does not allocate scarce resources to generate the greatest social welfare. A wedge exists between what a private person does given market prices and what society might want him or her to do to protect the environment. Such a wedge implies wastefulness or economic inefficiency; resources can be reallocated to make at least one person better off without making anyone else worse off." This results in a inefficient market that needs to be corrected through avenues such as government intervention. Common forms of market failure include externalities, non-excludability and non-rivalry.

Externality

An externality exists when a person makes a choice that affects other people in a way that is not accounted for in the market price. An externality can be positive or negative but is usually associated with negative externalities in environmental economics. For instance, water seepage in residential buildings occurring in upper floors affect the lower floors. Another example concerns how the sale of Amazon timber disregards the amount of carbon dioxide released in the cutting. Or a firm emitting pollution will typically not take into account the costs that its pollution imposes on others. As a result, pollution may occur in excess of the 'socially efficient' level, which is the level that would exist if the market was required to account for the pollution. A classic definition influenced by Kenneth Arrow and James Meade is provided by Heller and Starrett (1976), who define an externality as "a situation in which the private economy lacks sufficient incentives to create a potential market in some good and the nonexistence of this market results in losses of Pareto efficiency". In economic terminology, externalities are examples of market failures, in which the unfettered market does not lead to an efficient outcome.

Common goods and public goods

When it is too costly to exclude some people from access to an environmental resource, the resource is either called a common property resource (when there is rivalry for the resource, such that one person's use of the resource reduces others' opportunity to use the resource) or a public good (when use of the resource is non-rivalrous). In either case of non-exclusion, market allocation is likely to be inefficient.

These challenges have long been recognized. Hardin's (1968) concept of the tragedy of the commons popularized the challenges involved in non-exclusion and common property. "Commons" refers to the environmental asset itself, "common property resource" or "common pool resource" refers to a property right regime that allows for some collective body to devise schemes to exclude others, thereby allowing the capture of future benefit streams; and "open-access" implies no ownership in the sense that property everyone owns nobody owns.

The basic problem is that if people ignore the scarcity value of the commons, they can end up expending too much effort, over harvesting a resource (e.g., a fishery). Hardin theorizes that in the absence of restrictions, users of an open-access resource will use it more than if they had to pay for it and had exclusive rights, leading to environmental degradation. See, however, Ostrom's (1990) work on how people using real common property resources have worked to establish self-governing rules to reduce the risk of the tragedy of the commons.

The mitigation of climate change effects is an example of a public good, where the social benefits are not reflected completely in the market price. Because the personal marginal benefits are less than the social benefits the market under-provides climate change mitigation. This is a public good since the risks of climate change are both non-rival and non-excludable. Such efforts are non-rival since climate mitigation provided to one does not reduce the level of mitigation that anyone else enjoys. They are non-excludable actions as they will have global consequences from which no one can be excluded. A country's incentive to invest in carbon abatement is reduced because it can "free ride" off the efforts of other countries. Over a century ago, Swedish economist Knut Wicksell (1896) first discussed how public goods can be under-provided by the market because people might conceal their preferences for the good, but still enjoy the benefits without paying for them.

Valuation

Assessing the economic value of the environment is a major topic within the field. The values of natural resources often are not reflected in prices that markets set and, in fact, many of them are available at no monetary charge. This mismatch frequently causes distortions in pricing of natural assets: both overuse of them and underinvestment in them. Economic value or tangible benefits of ecosystem services and, more generally, of natural resources, include both use and indirect (see the nature section of ecological economics). Non-use values include existence, option, and bequest values. For example, some people may value the existence of a diverse set of species, regardless of the effect of the loss of a species on ecosystem services. The existence of these species may have an option value, as there may be the possibility of using it for some human purpose. For example, certain plants may be researched for drugs. Individuals may value the ability to leave a pristine environment for their children.

Use and indirect use values can often be inferred from revealed behavior, such as the cost of taking recreational trips or using hedonic methods in which values are estimated based on observed prices. These use values can also be predicted through defensive behavior against pollution or environmental hazards, which can reveal how much people are willing to spend on healthcare and other preventative measures to avoid these hazards. Another health-based predictor of environmental use value is the value of a statistical life (VSL), which provides an estimate of how much people are willing to pay for small reductions in their risk of dying from environmental hazards. Non-use values are usually estimated using stated preference methods such as contingent valuation or choice modelling. Contingent valuation typically takes the form of surveys in which people are asked how much they would pay to observe and recreate in the environment (willingness to pay) or their willingness to accept (WTA) compensation for the destruction of the environmental good. Hedonic pricing examines the effect the environment has on economic decisions through housing prices, traveling expenses, and payments to visit parks.

State subsidy

Almost all governments and states magnify environmental harm by providing various types of subsidies that have the effect of paying companies and other economic actors more to exploit natural resources than to protect them. The damage to nature of such public subsidies has been conservatively estimated at $4-$6 trillion U.S. dollars per year.

Solutions

Solutions advocated to correct such externalities include:

  • Environmental regulations. Under this plan, the economic impact has to be estimated by the regulator. Usually, this is done using cost–benefit analysis. There is a growing realization that regulations (also known as "command and control" instruments) are not so distinct from economic instruments as is commonly asserted by proponents of environmental economics. E.g.1 regulations are enforced by fines, which operate as a form of tax if pollution rises above the threshold prescribed. E.g.2 pollution must be monitored and laws enforced, whether under a pollution tax regime or a regulatory regime. The main difference an environmental economist would argue exists between the two methods, however, is the total cost of the regulation. "Command and control" regulation often applies uniform emissions limits on polluters, even though each firm has different costs for emissions reductions, i.e., some firms, in this system, can abate pollution inexpensively, while others can only abate it at high cost. Because of this, the total abatement in the system comprises some expensive and some inexpensive efforts. Consequently, modern "Command and control" regulations are oftentimes designed in a way that addresses these issues by incorporating utility parameters. For instance, CO2 emission standards for specific manufacturers in the automotive industry are either linked to the average vehicle footprint (US system) or average vehicle weight (EU system) of their entire vehicle fleet. Environmental economic regulations find the cheapest emission abatement efforts first, and then move on to the more expensive methods. E.g. as said earlier, trading, in the quota system, means a firm only abates pollution if doing so would cost less than paying someone else to make the same reduction. This leads to a lower cost for the total abatement effort as a whole.
  • Quotas on pollution. Often it is advocated that pollution reductions should be achieved by way of tradeable emissions permits, which if freely traded may ensure that reductions in pollution are achieved at least cost. In theory, if such tradeable quotas are allowed, then a firm would reduce its own pollution load only if doing so would cost less than paying someone else to make the same reduction, i.e., only if buying tradeable permits from another firm(s) is costlier. These tradeable permit approaches can also, in theory, improve economic efficiency and cost-effectiveness while increasing government revenue through the use of permit auctions instead of grandfathering practices. This entails the government selling off a certain number of these tradeable permits, allowing the government to capture the value of emissions and use it to reduce marginal tax rates. In practice, tradeable permits approaches have had some success, such as the U.S.'s sulphur dioxide trading program or the EU Emissions Trading Scheme, and interest in its application is spreading to other environmental problems.
  • Taxes and tariffs on pollution. Increasing the costs of polluting will discourage polluting, and will provide a "dynamic incentive", that is, the disincentive continues to operate even as pollution levels fall. A pollution tax that reduces pollution to the socially "optimal" level would be set at such a level that pollution occurs only if the benefits to society (for example, in form of greater production) exceeds the costs. This concept was introduced by Arthur Pigou, a British economist active in the late nineteenth through the mid-twentieth century. He showed that these externalities occur when markets fail, meaning they do not naturally produce the socially optimal amount of a good or service. He argued that “a tax on the production of paint would encourage the [polluting] factory to reduce production to the amount best for society as a whole.” These taxes are known amongst economists as Pigouvian Taxes, and they regularly implemented where negative externalities are present. Some advocate a major shift from taxation from income and sales taxes to tax on pollution – the so-called "green tax shift".
  • Better defined property rights. The Coase Theorem states that assigning property rights will lead to an optimal solution, regardless of who receives them, if transaction costs are trivial and the number of parties negotiating is limited. For example, if people living near a factory had a right to clean air and water, or the factory had the right to pollute, then either the factory could pay those affected by the pollution or the people could pay the factory not to pollute. Or, citizens could take action themselves as they would if other property rights were violated. The US River Keepers Law of the 1880s was an early example, giving citizens downstream the right to end pollution upstream themselves if the government itself did not act (an early example of bioregional democracy). Many markets for "pollution rights" have been created in the late twentieth century—see emissions trading. Supply-side environmental policy implements efficiency by letting countries that are affected by climate change "buy coal" or other fossil fuel reserves abroad with the intention of conserving them: Bohm (1993); Harstad (2012). According to the Coase Theorem, the involved parties will bargain with each other, which results in an efficient solution. However, modern economic theory has shown that the presence of asymmetric information may lead to inefficient bargaining outcomes. Specifically, Rob (1989) has shown that pollution claim settlements will not lead to the socially optimal outcome when the individuals that will be affected by pollution have learned private information about their disutility already before the negotiations take place. Goldlücke and Schmitz (2018) have shown that inefficiencies may also result if the parties learn their private information only after the negotiations, provided that the feasible transfer payments are bounded. Using cooperative game theory, Gonzalez, Marciano and Solal (2019) have shown that in social cost problems involving more than three agents, the Coase theorem suffers from many counterexamples and that only two types of property rights lead to an optimal solution.
  • Accounting for environmental externalities in the final price. In fact, the world's largest industries burn about $7.3 trillion of free natural capital per year. Thus, the world's largest industries would hardly be profitable if they had to pay for this destruction of natural capital. Trucost has assessed over 100 direct environmental impacts and condensed them into 6 key environmental performance indicators (EKPIs). The assessment of environmental impacts is derived from different sources (academic journals, governments, studies, etc.) due to the lack of market prices. The table below gives an overview of the 5 regional sectors per EKPI with the highest impact on the overall EKPI:
Ranking of the 5 region-sectors by EKPI with the greatest impact across all EKPIs when measured in monetary terms

2 Land Use Cattle Ranching and Farming South America 312.1 16.6 18.7
3 GHG Iron and Steel Mills Eastern Asia 216.1 604.7 0.4
4 Water Wheat Farming Southern Asia 214.4 31.8 6.7
5 GHG Coal Power Generation Northern America 201.0 246.7 0.8

If companies are allowed to include some of these externalities in their final prices, this could undermine the Jevons paradox and provide enough revenue to help companies innovate.

Relationship to other fields

Environmental economics is related to ecological economics but there are differences. Most environmental economists have been trained as economists. They apply the tools of economics to address environmental problems, many of which are related to so-called market failures—circumstances wherein the "invisible hand" of economics is unreliable. Most ecological economists have been trained as ecologists, but have expanded the scope of their work to consider the impacts of humans and their economic activity on ecological systems and services, and vice versa. This field takes as its premise that economics is a strict subfield of ecology. Ecological economics is sometimes described as taking a more pluralistic approach to environmental problems and focuses more explicitly on long-term environmental sustainability and issues of scale.

Environmental economics is viewed as more idealistic in a price system; ecological economics as more realistic in its attempts to integrate elements outside of the price system as primary arbiters of decisions. These two groups of specialisms sometimes have conflicting views which may be traced to the different philosophical underpinnings.

Another context in which externalities apply is when globalization permits one player in a market who is unconcerned with biodiversity to undercut prices of another who is – creating a race to the bottom in regulations and conservation. This, in turn, may cause loss of natural capital with consequent erosion, water purity problems, diseases, desertification, and other outcomes that are not efficient in an economic sense. This concern is related to the subfield of sustainable development and its political relation, the anti-globalization movement.

The three pillars of sustainability 

Environmental economics was once distinct from resource economics. Natural resource economics as a subfield began when the main concern of researchers was the optimal commercial exploitation of natural resource stocks. But resource managers and policy-makers eventually began to pay attention to the broader importance of natural resources (e.g. values of fish and trees beyond just their commercial exploitation). It is now difficult to distinguish "environmental" and "natural resource" economics as separate fields as the two became associated with sustainability. Many of the more radical green economists split off to work on an alternate political economy.

Environmental economics was a major influence on the theories of natural capitalism and environmental finance, which could be said to be two sub-branches of environmental economics concerned with resource conservation in production, and the value of biodiversity to humans, respectively. The theory of natural capitalism (Hawken, Lovins, Lovins) goes further than traditional environmental economics by envisioning a world where natural services are considered on par with physical capital.

The more radical green economists reject neoclassical economics in favour of a new political economy beyond capitalism or communism that gives a greater emphasis to the interaction of the human economy and the natural environment, acknowledging that "economy is three-fifths of ecology". This political group is a proponent of a transition to renewable energy.

These more radical approaches would imply changes to money supply and likely also a bioregional democracy so that political, economic, and ecological "environmental limits" were all aligned, and not subject to the arbitrage normally possible under capitalism.

An emerging sub-field of environmental economics studies its intersection with development economics. Dubbed "envirodevonomics" by Michael Greenstone and B. Kelsey Jack in their paper "Envirodevonomics: A Research Agenda for a Young Field", the sub-field is primarily interested in studying "why environmental quality [is] so poor in developing countries." A strategy for better understanding this correlation between a country's GDP and its environmental quality involves analyzing how many of the central concepts of environmental economics, including market failures, externalities, and willingness to pay, may be complicated by the particular problems facing developing countries, such as political issues, lack of infrastructure, or inadequate financing tools, among many others.

In the field of law and economics, environmental law is studied from an economic perspective. The economic analysis of environmental law studies instruments such as zoning, expropriation, licensing, third party liability, safety regulation, mandatory insurance, and criminal sanctions. A book by Michael Faure (2003) surveys this literature.
