Research output: Contribution to journalArticle

5 Scopus citations


An axiomatization proposed by Coombs 1974 is shown to be insufficient for the representation of gambles in a risk × expected value space as described by Portfolio Theory. A new axiom system is given which is necessary and sufficient for this representation, and which implies the old axiomatization.
