On the accessibility of the core

Author

  • Yang, Yi-You

Abstract

We define a new notion of dominance, sequential z-dominance, and show that for any TU game with a nonempty core, every process of successive blocks must terminate in the core if the notion of sequential z-dominance is employed. Moreover, this result leads to an upper bound for the number of blocks needed to reach the core, which is lower than the one given in Kóczy (2006).
