In two laboratory studies involving 285 undergraduate students presented with a one-shot real choice we observe a systematic influence of time delay on the preferences for two lotteries, equal in expected value, but different in the degree of probability and outcome. The more the outcome is...

In this paper, we show that the third inverse stochastic dominances introduced by Muliere and Scarsini (1989) is nicely connected with the Yaari's dual model. We show especially that the third inverse stochastic dominance is closely linked with the non-negativity of third derivative of the...

The attitude of future generations towards environmental assets could be different from ours, and it is necessary to take into account explicitly this possibility in the current debate about environmental policy. The question we address here is : should uncertainty about future preferences lead...
