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 …
