Vilfredo Pareto (80 20 rule): Biography, Quotes & Books
Vilfredo Pareto (1848 – 1923) was an Italian engineer, sociologist, economist, scientist and philosopher. During his career he made several important contributions to economics, including a study of national income distribution and tools to analyse individual choices. One of his best known theories is the 80-20 rule which was later developed by Joseph M. Juran. This article covers his biography, quotes and publications.
Biography Vilfredo Pareto
Vilfredo Pareto earned a Master’s degree in Engineering (MSc.) from what is now the Polytechnic University of Turin in 1870. A few years later he obtained his doctor’s degree (Ph.D.) at the same university with his dissertation ‘The Fundamental Principles of Equilibrium in Solid Bodies’.
His interest in economics and sociology can be traced back in the equilibrium analyses.
Shortly after he had obtained his doctorate, he went to work as a civil engineer for the Italian Railway Company. Vilfredo Pareto worked there for a number of years after which he became more and more interested in the liberalization of the free market.
In 1886, Vilfredo Pareto changed his career by becoming a lecturer on management and economics at the University of Florence in Italy. Vilfredo Pareto settled there and his stay was marked by political activity as he was frustrated with government regulations.
In 1893 Vilfredo Pareto moved to Switzerland because he was offered a lecturer’s position at the University of Lausanne.
In 1906 Pareto made a ground breaking observation, namely that 20% of the Italian population owned 80% of the property.
This observation/ insight was later generalised in several areas within the field of economics. Joseph Juran referred to this observation as the ‘Pareto Principle’, which is also globally known as the 80-20 rule.
