Rather than focusing on a specific theory of choice, our objective is to formulate a general...

This paper provides an analysis of individual and social decision criteria foralternatives that are composed of several attributes. We derive additive and multiplicativecriteria for individual decision-making with new axioms and apply these criteria toobtain new justications of known social...
