Résumé
We describe an experimental project on behaviour of individuals facing a sequential decision problem. Our purpose is to test whether experimental subjects satisfy the consequentialist hypothesis (Hammond, 1988) and to identify their behavioural strategies in a risky context Our experimental design allows us to distinguish behavioural strategies among non-consequentialist subjects. We distinguish subjects who apply Bayesian-Nash rationality in a multiple-selves game (Karni & Safra 1989) from those who apply a “cooperative strategy” among selves (Nielsen & Jaffray, 2006).
