Vilfredo Federico Damaso Pareto (; July 15, 1848 – August 19, 1923), born Wilfried Fritz Pareto, was an Italian industrialist, sociologist, economist, and philosopher, who developed a somewhat jaundiced view of the human enterprise. He made several important contributions to economics, particularly in the study of income distribution and in the analysis of individuals' choices. "His legacy as an economist was profound. Partly because of him, the field evolved from a branch of social philosophy as practiced 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." He introduced the concept of Pareto efficiency and helped develop the field of microeconomics. He also was the first to discover that Income followed a Pareto Distribution, which is a power law probability distribution. He also contributed to the fields of sociology and mathematics.
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, his mother, Marie Metenier, a French woman. Enthusiastic about the 1848 German revolution, his parents named him Fritz Wilfried, which became Vilfredo Federico upon his family's move back to Italy in 1858. In his childhood, Pareto lived in a middle-class environment, receiving a high standard of education. In 1867, he earned a degree in mathematical sciences and in 1870 a doctorate in engineering from what is now the Polytechnic University of Turin. His dissertation was 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 paper.
Civil engineer to liberal to 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 did not begin serious work in economics until his mid forties. He started his career a fiery liberal, besting 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 Bakunin. She later left him for a young servant.
Economics and sociology
In 1893, he was appointed a lecturer in economics at the University of Lausanne in Switzerland where he remained for the rest of his life. 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). In one of his books published in 1909 he showed the Pareto distribution of how wealth is distributed, he believed "through any human society, in any age, or country". Later in life He began writing numerous polemical articles against the government, which caused him much trouble. His observations about the Pareto distribution had changed him from an ardent free enterprise apologist to somewhat of a socialist, and after his death a champion of Italian and other fascists.
He also remarried. He died in Geneva, Switzerland, August 19, 1923, "among a menagerie of cats that he and his french lover kept" in their villa; "the local divorce laws prevented him from divorcing his wife and remarrying until just a few months before his death."
Fascism and power distribution
Benoit Mandelbrot writes:
"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? 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."
Pareto's discovery that power laws applied to income distribution embroiled him in political change and the nascent fascist movement, whether he really sided with them or not. Fascists such as Mussolini found inspiration for their own economic ideas in his discoveries. He had discovered something that was harsh and Darwinian, in Pareto's view. And this fueled both the anger and the energy of the Fascist movement because it fueled their economic and social views. He wrote that, as Mandelbrot summarizes:
"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."
Vilfredo 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.
He had calculated a power curve and an alpha of 3/2 for the slope of that line. And he thought from the measures and his calculations that he'd found an "iron law" though in reality he'd discovered something more prosaic. People since then have gone back and recalculated the slope, found it varied from place to place and time to time, and should be closer to 2.
To quote Pareto's 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".
Karl Popper called him the "Theoretician of Totalitarianism."
Pareto was sympathetic to Mussolini, largely because Mussolini claimed to be championing ideas congruent to the ones he had just expressed and Mussolini had admired his ideas. He accepted a "royal" nomination to the Italian senate from his admirer, Mussolini. We will never know if he truly was a supporter of Fascism because he died less than a year into the new regime's existence. However, on being sent an anti-Semitic book, Pareto's reply indicated no repulsion for it.
The fascist writers were much enamoured of Pareto, writing paeans such as the following of his:
"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."
But the truth is he'd simply quantified an observation of the human condition. In most societies a few people are outrageously rich, a small number very rich, most people in the middle or poor.
Economic rules
A few economic rules are based on his work:
- The Pareto index is a measure of the inequality of income distribution.
- The Pareto chart is a special type of histogram, used to view causes of a problem in order of severity from largest to smallest. It is a statistical tool that graphically demonstrates the Pareto principle or the 80-20 rule.
- Pareto's law concerns the distribution of income.
- The Pareto distribution is a probability distribution used, among other things, as a mathematical realization of Pareto's law.
