This paper is concerned with the question of how to define the core when cooperation takes place in a dynamic setting …-games. Three different core concepts are presented: the classical core, the strong sequential core and the weak sequential core …. Sufficient conditions are given for nonemptiness of the classical core in general and of the weak sequential core for the case of …

This paper studies the core of combined games, obtained by summing two coalitional games. It is shown that the set of … core of the combined game coincides with the sum of the cores of its components. On the other hand, for non-balanced games …, the binary relation associating two component games whose combination has an empty core is not transitive. However, we …
