Vilfredo Federico Damaso Pareto [3] ( UK: /pæˈrt,-ˈrt-/ pa-RAY-toh, -EE-, [4] US: /pəˈrt/ pə-RAY-toh, [5] Italian:  [vilˈfreːdo paˈreːto] , Ligurian:  [paˈɾeːtu] ; born Wilfried Fritz Pareto[ citation needed ]; 15 July 1848 – 19 August 1923) was an Italian civil engineer, sociologist, economist, political scientist, and philosopher. He made several important contributions to economics, particularly in the study of income distribution and in the analysis of individuals' choices. He was also responsible for popularising the use of the term "elite" in social analysis.

Contents

He introduced the concept of Pareto efficiency and helped develop the field of microeconomics. He was also the first to discover that income follows a Pareto distribution, which is a power law probability distribution. The Pareto principle was named after him, and it was built on observations of his such as that 80% of the wealth in Italy belonged to about 20% of the population. He also contributed to the fields of sociology and mathematics, according to the mathematician Benoit Mandelbrot and Richard L. Hudson:

His legacy as an economist was profound. Partly because of him, the field evolved from a branch of moral philosophy as practised by Adam Smith into a data intensive field of scientific research and mathematical equations. His books look more like modern economics than most other texts of that day: tables of statistics from across the world and ages, rows of integral signs and equations, intricate charts and graphs. [6]

Biography

Pareto was born of an exiled noble Genoese family in 1848 in Paris, the centre of the popular revolutions of that year. His father, Raffaele Pareto (1812–1882), was an Italian civil engineer and Ligurian marquis who had left Italy much as Giuseppe Mazzini and other Italian nationalists had. [7] His mother, Marie Metenier, was a French woman. Enthusiastic about the revolutions of 1848 in the German states, his parents named him Wilfried Fritz, which became Vilfredo Federico upon his family's move back to Italy in 1858. [8] In his childhood, Pareto lived in a middle-class environment, receiving a high standard of education, attending the newly created Istituto Tecnico Leardi where Fernando Pio Rosellini was his mathematics professor. [9] In 1869, he earned a doctorate in engineering from what is now the Polytechnic University of Turin [7] (then the Technical School for Engineers), with a dissertation entitled "The Fundamental Principles of Equilibrium in Solid Bodies". His later interest in equilibrium analysis in economics and sociology can be traced back to this dissertation.

From civil engineer to classical liberal economist

For some years after graduation, he worked as a civil engineer, first for the state-owned Italian Railway Company and later in private industry. He was manager of the Iron Works of San Giovanni Valdarno and later general manager of Italian Iron Works. [7]

He did not begin serious work in economics until his mid-forties. He started his career a fiery advocate of classical liberalism, besetting the most ardent British liberals with his attacks on any form of government intervention in the free market. In 1886, he became a lecturer on economics and management at the University of Florence. His stay in Florence was marked by political activity, much of it fueled by his own frustrations with government regulators. In 1889, after the death of his parents, Pareto changed his lifestyle, quitting his job and marrying a Russian, Alessandrina Bakunina. [10]

Economics and sociology

In 1893, he succeeded Léon Walras to the chair of Political Economy at the University of Lausanne in Switzerland where he remained for the rest of his life. [7] He published there in 1896-1897 a textbook containing the Pareto distribution of how wealth is distributed, which he believed was a constant "through any human society, in any age, or country". [7] In 1906, he made the famous observation that twenty percent of the population owned eighty percent of the property in Italy, later generalised by Joseph M. Juran into the Pareto principle (also termed the 80–20 rule).

Pareto maintained cordial personal relationships with individual socialists, but he always thought their economic ideas were severely flawed. He later became suspicious of their motives and denounced socialist leaders as an 'aristocracy of brigands' who threatened to despoil the country and criticized the government of Giovanni Giolitti for not taking a tougher stance against worker strikes. Growing unrest among labor in Italy led him to the anti-socialist and anti-democratic camp. [11] His attitude toward fascism in his last years is a matter of controversy. [12] [13]

Pareto's relationship with scientific sociology in the age of the foundation is grafted in a paradigmatic way in the moment in which he, starting from the political economy, criticizes positivism as a totalizing and metaphysical system devoid of a rigorous logical-experimental method. In this sense we can read the fate of the Paretian production within a history of the social sciences that continues to show its peculiarity and interest for its contributions in the 21st century. [14] The story of Pareto is also part of the multidisciplinary research of a scientific model that privileges sociology as a critique of cumulative models of knowledge as well as a discipline tending to the affirmation of relational models of science. [15] [16]

Personal life

In 1889, Pareto married Alessandrina Bakunina, a Russian. She left him in 1902 for a young servant. Twenty years later in 1923, he married Jeanne Regis, a French woman, just before his death in Geneva, Switzerland on 19 August 1923. [10]

Sociology

Pareto's later years were spent in collecting the material for his best-known work, Trattato di sociologia generale (1916) (The Mind and Society, published in 1935). His final work was Compendio di sociologia generale (1920).

In his Trattato di Sociologia Generale (1916, rev. French trans. 1917), published in English by Harcourt, Brace in a four-volume edition edited by Arthur Livingston under the title The Mind and Society (1935), Pareto developed the notion of the circulation of elites, the first social cycle theory in sociology. He is famous for saying "history is a graveyard of aristocracies". [17]

Pareto seems to have turned to sociology for an understanding of why his abstract mathematical economic theories did not work out in practice, in the belief that unforeseen or uncontrollable social factors intervened. His sociology holds that much social action is nonlogical and that much personal action is designed to give spurious logicality to non-rational actions. We are driven, he taught, by certain "residues" and by "derivations" from these residues. The more important of these have to do with conservatism and risk-taking, and human history is the story of the alternate dominance of these sentiments in the ruling elite, which comes into power strong in conservatism but gradually changes over to the philosophy of the "foxes" or speculators. A catastrophe results, with a return to conservatism; the "lion" mentality follows. This cycle might be broken by the use of force, says Pareto, but the elite becomes weak and humanitarian and shrinks from violence. [18]

Among those who introduced Pareto's sociology to the United States were George Homans and Lawrence J. Henderson at Harvard, and Paretian ideas gained considerable influence, especially on Harvard sociologist Talcott Parsons, who developed a systems approach to society and economics that argues the status quo is usually functional. [19] The American historian Bernard DeVoto played an important role in introducing Pareto's ideas to these Cambridge intellectuals and other Americans in the 1930s. Wallace Stegner, in his biography of DeVoto, recounts these developments and says this about the often misunderstood distinction between "residues" and "derivations": "Basic to Pareto's method is the analysis of society through its non-rational 'residues,' which are persistent and unquestioned social habits, beliefs, and assumptions, and its 'derivations,' which are the explanations, justifications, and rationalizations we make of them.  One of the commonest errors of social thinkers is to assume rationality and logic in social attitudes and structures; another is to confuse residues and derivations." [20]

Pareto was a lifelong opponent of Marxism. [21]

Fascism and power distribution

Renato Cirillo wrote:

Vilfredo Pareto has been labelled a fascist and ‘a precursor of fascism’ largely because he welcomed the advent of fascism in Italy and was honored by the new regime. Some have seen in his sociological works the foundations of fascism. This is not correct. Even fascist writers did not find much merit in these works, and definitely condemned his economic theories. As a political thinker he remained a radical libertarian till the end, and continued to express serious reservations about fascism, and to voice opposition to its basic policies. This is evident from his correspondence with his close friends. There are strong reasons to believe that, had he lived long enough, Pareto would have revolted against fascism. [22]

Benoit Mandelbrot wrote:

One of Pareto's equations achieved special prominence, and controversy. He was fascinated by problems of power and wealth. How do people get it? How is it distributed around society? How do those who have it use it? The gulf between rich and poor has always been part of the human condition, but Pareto resolved to measure it. He gathered reams of data on wealth and income through different centuries, through different countries: the tax records of Basel, Switzerland, from 1454 and from Augsburg, Germany, in 1471, 1498 and 1512; contemporary rental income from Paris; personal income from Britain, Prussia, Saxony, Ireland, Italy, Peru. What he found – or thought he found – was striking. When he plotted the data on graph paper, with income on one axis, and number of people with that income on the other, he saw the same picture nearly everywhere in every era. Society was not a "social pyramid" with the proportion of rich to poor sloping gently from one class to the next. Instead it was more of a "social arrow" – very fat on the bottom where the mass of men live, and very thin at the top where sit the wealthy elite. Nor was this effect by chance; the data did not remotely fit a bell curve, as one would expect if wealth were distributed randomly. "It is a social law", he wrote: something "in the nature of man". [23] :153

Pareto had argued that democracy was an illusion and that a ruling class always emerged and enriched itself. For him, the key question was how actively the rulers ruled. For this reason, he called for a drastic reduction of the state and welcomed Benito Mussolini's rule as a transition to this minimal state so as to liberate the "pure" economic forces. [24]

Mandelbrot summarized Pareto's notions as follows:

At the bottom of the Wealth curve, he wrote, Men and Women starve and children die young. In the broad middle of the curve all is turmoil and motion: people rising and falling, climbing by talent or luck and falling by alcoholism, tuberculosis and other kinds of unfitness. At the very top sit the elite of the elite, who control wealth and power for a time – until they are unseated through revolution or upheaval by a new aristocratic class. There is no progress in human history. Democracy is a fraud. Human nature is primitive, emotional, unyielding. The smarter, abler, stronger, and shrewder take the lion's share. The weak starve, lest society become degenerate: One can, Pareto wrote, 'compare the social body to the human body, which will promptly perish if prevented from eliminating toxins.' Inflammatory stuff – and it burned Pareto's reputation. [23] :154

The future leader of Italian fascism Benito Mussolini, in 1904, when he was a young student, attended some of Pareto's lectures at the University of Lausanne. It has been argued that Mussolini's move away from socialism towards a form of "elitism" may be attributed to Pareto's ideas. [25]

To quote Franz Borkenau, a biographer:

In the first years of his rule Mussolini literally executed the policy prescribed by Pareto, destroying political liberalism, but at the same time largely replacing state management of private enterprise, diminishing taxes on property, favoring industrial development, imposing a religious education in dogmas. [26] :18

Karl Popper dubbed Pareto the "theoretician of totalitarianism", [27] but, according to Renato Cirillo, there is no evidence in Popper's published work that he read Pareto in any detail before repeating what was then a common but dubious judgment in anti-fascist circles. [12]

Some fascist writers, such as Luigi Amoroso, wrote approvingly of Pareto's ideas:

Just as the weaknesses of the flesh delayed, but could not prevent, the triumph of Saint Augustine, so a rationalistic vocation retarded but did not impede the flowering of the mysticism of Pareto. For that reason, Fascism, having become victorious, extolled him in life, and glorifies his memory, like that of a confessor of its faith. [7]

Author Renato Cirillo argued, on the contrary, that:

Some have seen in [Pareto's] sociological works the foundations of fascism. This is not correct. Even fascist writers did not find much merit in these works, and definitely condemned his economic theories. [12]

Pareto's elite theory also influenced a number of liberal theorists, such as the anti-fascist Piero Gobetti, who wrote:

The concept of an elite that imposes itself by exploiting a channel of interests and general psychological conditions against the old leaders who have exhausted their function is genuinely liberal. [28]

Other liberals influenced by Pareto include Norberto Bobbio and Raymond Aron. [29]

Economic concepts

Pareto Theory Of Maximum Economics

Pareto turned his interest to economic matters and he became an advocate of free trade, finding himself in difficulty with the Italian government. His writings reflected the ideas of Léon Walras that economics is essentially a mathematical science. Pareto was a leader of the "Lausanne School" and represents the second generation of the Neoclassical Revolution. His "tastes-and-obstacles" approach to general equilibrium theory was resurrected during the great "Paretian Revival" of the 1930s and has influenced theoretical economics since. [30]

In his Manual of Political Economy (1906) the focus is on equilibrium in terms of solutions to individual problems of "objectives and constraints". He used the indifference curve of Edgeworth (1881) extensively, for the theory of the consumer and, another great novelty, in his theory of the producer. He gave the first presentation of the trade-off box now known as the "Edgeworth-Bowley" box. [31]

Pareto was the first to realize that cardinal utility could be dispensed with and economic equilibrium thought of in terms of ordinal utility [32] – that is, it was not necessary to know how much a person valued this or that, only that he preferred X of this to Y of that. Utility was a preference-ordering. With this, Pareto not only inaugurated modern microeconomics, but he also demolished the alliance of economics and utilitarian philosophy (which calls for the greatest good for the greatest number; Pareto said "good" cannot be measured). He replaced it with the notion of Pareto-optimality , the idea that a system is enjoying maximum economic satisfaction when no one can be made better off without making someone else worse off. Pareto optimality is widely used in welfare economics and game theory. A standard theorem is that a perfectly competitive market creates distributions of wealth that are Pareto optimal. [33]

Concepts

Some economic concepts in current use are based on his work:

He argued that in all countries and times, the distribution of income and wealth is highly skewed, with a few holding most of the wealth. He argued that all observed societies follow a regular logarithmic pattern:

where N is the number of people with wealth higher than x, and A and m are constants. Over the years, Pareto's Law has proved remarkably close to observed data.

Corrado Gini was an Italian statistician, demographer and sociologist who developed the Gini coefficient, a measure of the income inequality in a society. Gini was a proponent of organicism and applied it to nations. Gini was a eugenicist, and prior to and during World War II, he was an advocate of Italian Fascism. Following the war, he founded the Italian Unionist Movement, which advocated for the annexation of Italy by the United States.

Political sociology Branch of sociology

Political sociology is an interdisciplinary field of study concerned with exploring how governance and society interact and influence one another at the micro to macro levels of analysis. Interested in the social causes and consequences of how power is distributed and changes throughout and amongst societies, political sociology's focus ranges across individual families to the State as sites of social and political conflict and power contestation.

Benedetto Croce was an Italian idealist philosopher, historian, and politician, who wrote on numerous topics, including philosophy, history, historiography and aesthetics. In most regards, Croce was a liberal, although he opposed laissez-faire, free trade, and had considerable influence on other Italian intellectuals, including both Marxist Antonio Gramsci and Italian Fascist Giovanni Gentile.

Norberto Bobbio Italian legal scholar (1909–2004)

Norberto Bobbio was an Italian philosopher of law and political sciences and a historian of political thought. He also wrote regularly for the Turin-based daily La Stampa. Bobbio was a social liberal in the tradition of Piero Gobetti, Carlo Rosselli, Guido Calogero, and Aldo Capitini. He was also strongly influenced by Hans Kelsen and Vilfredo Pareto.

A mass movement denotes a political party or movement which is supported by large segments of a population. Political movements that typically advocate the creation of a mass movement include the ideologies of communism, fascism, and liberalism. Both communists and fascists typically support the creation of mass movements as a means to overthrow a government and create their own government, the mass movement then being used afterwards to protect the government from being overthrown itself; whereas liberals seek mass participation in the state apparatus of representative democracy.

Historians and other scholars disagree on the question of whether a specifically fascist type of economic policy can be said to exist. David Baker argues that there is an identifiable economic system in fascism that is distinct from those advocated by other ideologies, comprising essential characteristics that fascist nations shared. Payne, Paxton, Sternhell et al. argue that while fascist economies share some similarities, there is no distinctive form of fascist economic organization. Gerald Feldman and Timothy Mason argue that fascism is distinguished by an absence of coherent economic ideology and an absence of serious economic thinking. They state that the decisions taken by fascist leaders cannot be explained within a logical economic framework.

Gaetano Mosca Italian political scientist and journalist

Gaetano Mosca was an Italian political scientist, journalist and public servant. He is credited with developing the elite theory and the doctrine of the political class and is one of the three members constituting the Italian school of elitism together with Vilfredo Pareto and Robert Michels.

The Lange model is a neoclassical economic model for a hypothetical socialist economy based on public ownership of the means of production and a trial-and-error approach to determining output targets and achieving economic equilibrium and Pareto efficiency. In this model, the state owns non-labor factors of production, and markets allocate final goods and consumer goods. The Lange model states that if all production is performed by a public body such as the state, and there is a functioning price mechanism, this economy will be Pareto-efficient, like a hypothetical market economy under perfect competition. Unlike models of capitalism, the Lange model is based on direct allocation, by directing enterprise managers to set price equal to marginal cost in order to achieve Pareto efficiency. By contrast, in a capitalist economy, private owners seek to maximize profits, while competitive pressures are relied on to indirectly lower the price, this discourages production with high marginal cost and encourages economies of scale.

Enrico Ferri (criminologist)

Enrico Ferri was an Italian criminologist, socialist and student of Cesare Lombroso, the founder of the Italian school of criminology. While Lombroso researched the purported physiological factors that motivated criminals, Ferri investigated social and economic aspects. He served as editor of the socialist daily Avanti! and, in 1884, saw his book Criminal Sociology published. Later, his work served as the basis for Argentina’s penal code of 1921. Although at first he rejected the Italian dictator Benito Mussolini, Ferri later became one of Mussolini and his National Fascist Party's main external supporters.

In political science and sociology, elite theory is a theory of the State that seeks to describe and explain power relationships in contemporary society. The theory posits that a small minority, consisting of members of the economic elite and policy-planning networks, holds the most power—and that this power is independent of democratic elections.

The following events related to sociology occurred in the 1910s.

The circulation of elite is a theory of regime change described by Italian sociologist Vilfredo Pareto (1848–1923).

Bourgeois nation was a term coined by adherents of fascism, to refer to nations that had embraced what the fascists saw as decadent and materialistic lifestyles associated with standard bourgeois culture. Early fascist movements expressed contempt for "those who wanted only to earn money, filthy money," and denounced bourgeois culture as being too weak and individualistic to make a nation strong. Fascists idealized sport, physical activity, life in the open air, and virile athletic pursuits, which they contrasted with the image of "corpulent politicians", "great, sedentary bourgeois", and tobacco-smoking left-wing intellectuals in "anxious waiting for the hour of the aperitif." Italian Fascists also accused wealthy nations of hypocrisy because they built colonial empires in the past and then used the League of Nations to prevent nations like Italy from conquering colonies of their own. Nevertheless, despite these early denunciations of bourgeois culture and the pursuit of monetary gain, fascist parties in power helped large companies to achieve greater profits by banning strikes and lowering wages, and they "showered money on armaments industries, to the immense satisfaction of employers."
