The Discovery of the Gini Coefficient
追溯了20世纪初洛伦兹和基尼发展收入不平等度量方法的过程，指出基尼完善洛伦兹曲线可能促成了基尼系数的发现，并认为这是多重发现的典型案例。
This article traces the development of the methods of representing the degree of income inequality that were developed in the early twentieth century by Max Otto Lorenz and Corrado Gini. It suggests that Gini’s efforts to perfect the Lorenz curve may well have facilitated his discovery of what came to be known as the Gini coefficient and argues that this coefficient is an important example of a multiple (or chain multiple) discovery.
