Abstract

Let succeeds be a comparative probability relation on the set ℬ(S) of all subsets of a finite state space S. This paper presents and discusses necessary and sufficient axioms for several threshold models of succeeds, whose general representational form yields a probability measure P on ℬ(S) and a bivariate set function Omega>/=0 on ℬ(S)xℬ(S) such that for all A, Binℬ(S), A succeedsB if and only if P(A)>P(B)+Omega(A, B). Several conditions such as skew-monotonicity and additive separability will be imposed on the functional form of Omega. Copyright 2000 Academic Press.
