We propose a utility representation for preferences over risky timed outcomes, the weighted temporal utility model. It separates subjective evaluations of outcomes from attitudes towards psychological distance induced by risks and delays. Subjective evaluations of outcomes may depend on the time...

One of the main issues in economics is the trade-off between marginalism and egalitarianism. In the context of cooperative games this trade-off can be framed as one of choosing to allocate according to the Shapley value or the equal division solution. In this paper we provide tools that make it...
