Do we agree? Measuring the cohesiveness of preferences

  • Jorge Alcalde-Unzu
  • Marc Vorsatz

In this paper, we suggest new ways of how to measure the similarity of preferences in a group of individuals. For simplicity, we refer to this as the cohesiveness (of preferences). We propose axioms a cohesiveness measure should satisfy and show that these properties fully characterize a family of measures. According to it, the similarities between each pair of objects in a preference profile -calculated as the proportion margin by which one objects wins against the other in a pairwise comparison- are aggregated by a weighted mean. The weight of each pair of objects depends on their importance at the social level
