Sports inequalities using Gini coefficient and other inequality indices

Variations of competitiveness among sport teams directly affect to the economy of professional leagues. We measured the sports inequality in terms of wins, using different indices initially designed for measuring income inequality. Among these indices, Gini Coefficient is found to be powerful tool to analyze the inequalities associated with sports

Unifying approaches to consensus across different preference representations

© 2015 Elsevier B.V. All rights reserved. Consensus measures can be useful in group decision making problems both to guide users toward more reasonable judgments and to give an overall indication of the support for the final decision. The level of consensus between decision makers can be measured in contexts where preferences over alternatives are expressed either as evaluations or scores, pairwise preferences, and weak orders, however these different representations often call for different approaches to consensus measurements. In this paper, we look at the distance metrics used to construct consensus measures in each of these settings and how consistent these are for preference profiles when they are converted from one representation to another. We develop some methods for consistent approaches across decision making settings and provide an example to help investigate differences between some of the commonly used distances
