An element of the possibly unbounded core of a cooperative game with precedence constraints belongs to its bounded core … if any transfer to a player from any of her subordinates results in payoffs outside the core. The bounded core is the … union of all bounded faces of the core, it is nonempty if the core is nonempty, and it is a continuous correspondence on …

In cooperative games, the core is one of the most popular solution concept since it ensures coalitional rationality …. For non-balanced games however, the core is empty, and other solution concepts have to be found. We propose the use of … particular, the k-additive core proposed by Grabisch and Miranda is a general solution preserving coalitional rationality which …

In … possible payment (core element) and a single possible configuration. We also introduce the notion of inescapable coalitions …

The restricted core is obtained by imposing equality constraints in the core … for sets belonging to so-called normal collections, resulting (if nonempty) in the selection of a bounded face of the core …
