Abstract

This work analyzes the problem of individual choice of actions under complete uncertainty. In this context, each action consists of a set of di erent possible outcomes with no probability distribution associated with them. The work examines and de nes a class of choice procedures in which: a): the evaluation of sets (actions) is element- induced; and b): certain assumption of rationality, which is an adaptation of Sen's condition, is satis ed. Some results of characterization show that different well-known rules can be reinterpreted as particular cases within the de ned class, each of them responding to di erent attitudes towards uncertainty by the agent.
