We reconsider the problem of aggregating individual preference orderings into a single social ordering when alternatives are lotteries and individual preferences are of the von Neumann-Morgenstern type. Relative egalitarianism ranks alternatives by applying the leximin ordering to the distributions of (0-1) normalized utilities they generate. We propose an axiomatic characterization of this agg...

We present a consensus model for group decision making with unbalanced fuzzy linguistic preference relations, i.e., assuming that the preferences are assessed on linguistic term sets whose terms are not symmetrically and uniformly distributed. This consensus model can manage incomplete information situations, that is, situations where the experts do not give all the preference values that they ...

In order to elicit discount functions, experiments commonly analyze how subjects trade-off money and time. However, discounting reveals itself directly only in behavior obtained by fixing the money dimension and varying the time dimension. This paper presents an experimental procedure that, in a sense made precise, better identifies the discount function. The procedure is based on a general the...

The literature on self-control problems has typically concentrated on immediate temptations. This paper studies a Gul and Pesendorfer [13, 14] style model in which decision-makers are a¤ected by temptations that lie in the future. While temptation is commonly understood to give rise to a demand for commitment, it is shown that ‘temptation by future consumption’can induce its absence. The model ...
