Flippable Pairs and Subset Comparisons in Comparative Probability Orderings and Related Simple Games

We show that every additively representable comparative probability order on n atoms is determined by at least n - 1 binary subset comparisons. We show that there are many orders of this kind, not just the lexicographic order. These results provide answers to two questions of Fishburn et al (2002). We also study the flip relation on the class of all comparative probability orders introduced by Maclagan. We generalise an important theorem of Fishburn, Peke?c and Reeds, by showing that in any minimal set of comparisons that determine a comparative probability order, all comparisons are flippable. By calculating the characteristics of the flip relation for n = 6 we discover that the regions in the corresponding hyperplane arrangement can have no more than 13 faces and that there are 20 regions with 13 faces. All the neighbours of the 20 comparative probability orders which correspond to those regions are representable. Finally we define a class of simple games with complete desirability relation for which its strong desirability relation is acyclic, and show that the flip relation carries all the information about these games. We show that for n = 6 these games are weighted majority games.

Génétique et assurance vie : analyse comparative

Le débat autour du rôle de l’assurance vie, de la nécessité de recourir à un processus de sélection des risques et de la notion de discrimination acceptable a suscité un questionnement sur le rôle social de l’assurance. Ce débat a été exacerbé par les récents développements dans le domaine de la génétique humaine permettant aux assureurs d’utiliser les résultats de tests génétiques dans le processus de sélection des risques. Cet article présente une étude comparative des positions adoptées sur l’assurance et la génétique dans plusieurs pays. Nous analyserons les positions de 43 pays sélectionnés et commenterons leur capacité à assurer un accès plus équitable aux candidats à l’assurance vie.

Genetics and Life Insurance: A Comparative Analysis

The debate surrounding the role of life insurance, the necessity of risk rating, and the notion of “acceptable discrimination” has raised questions about the larger social role of insurance. Recent developments in the field of genetics, allowing insurers to make use of genetic testing technology as a new underwriting tool, have reinvigorated this debate. This article presents a comparative study of positions taken in countries on issues in genetics and life insurance. We will analyze the 43 selected countries and comment on their potential for ensuring a more equitable access for life insurance applicants.
