This paper deals with a constrained egalitarian solution for convex multi-choice games named the d value. It is proved that the d value of a convex multi-choice game belongs to the precore, Lorenz dominates each other element of the precore and possesses a population monotonicity property...

The object of study is cooperation in joint projects where agents may have different desired sophistication levels for the project and where some of the agents may have low budgets. In this context, questions concerning the optimal realizable sophistication level and the distribution of the...
