We compare the experimental results of three stag-hunt games. In contrast to Battalio et al.(2001), our design keeps the relative riskiness of the two strategies at a constant level as the optimisation premium is increased. Furthermore, we also test the effect of a decrease of the relative...

Prévention et précaution sont deux concepts bien différents, même si le premier peut être considéré comme un cas particulier du second lorsqu'aucune nouvelle information ne doit arriver dans le futur. Néanmoins, les deux concepts se rejoignent lorsqu'il s'agit d'envisager les problèmes...

One apparent reason for deferring a decision – abstaining from choosing, leaving the decision open to be taken by someone else, one’s later self, or nature – is for lack of sufficient confidence in the relevant beliefs. This paper develops an axiomatic theory of decision in situations...

We propose a task for eliciting attitudes towards risk that is close to real world risky decisions which typically involve gains and losses. The task consists of accepting or rejecting gambles that provide a gain with probability p and a loss with probability 1 − p. We employ finite mixture...
