Vilfredo Pareto
1848 - 1923 · Paris, Île-de-France, France
Pareto transformed economic theory by introducing indifference curves, shifting the field from cardinal utility to a framework based on ordinal preferences. He is best known for developing the concept of Pareto efficiency, which remains a cornerstone of welfare economics and resource allocation. His mathematical analysis of wealth distribution also laid the groundwork for modern power-law statistics and the study of social equilibrium.

Signature work
Discovery Story
Italian statistician Corrado Gini developed the coefficient in 1912 as a measure of statistical dispersion to quantify income and wealth inequality. His work, published in 'Variabilità e mutabilità', aimed to provide a single numerical value representing the degree of concentration within a distribution, significantly advancing the field of descriptive statistics beyond the graphical methods available at the time.
The coefficient was originally defined by Gini as the 'mean difference' of a distribution. Its modern geometric interpretation using the Lorenz curve became the standard pedagogical approach in economics decades later, facilitating its use in comparing national income distributions.
While the Gini coefficient was introduced by Corrado Gini, the specific formula Gini = A / (A + B) is a geometric interpretation derived from the Lorenz curve, which was developed independently by Max O. Lorenz in 1905.
