Weakened transitive rationality: Invariance of numerical representations of preferences Chapter uri icon

abstract

  • The ordinal invariance of utility functions representing the same preference is a fundamental issue for solving decision problems using mathematical techniques. As it is well known, this property holds when preferences are complete preorders. However, it is not necessarily verified for numerical representations of weaker concepts of preferences.Moreover, there are cases in which it is not possible to build order-preserving maps between two different numerical representations of the same preference. In this work, we characterize the classes of numerical representations that preserve the order introduced by a given preference in a set of alternatives. © Springer International Publishing Switzerland 2016.
