Abstract

This paper deals with the weak-core of normal form games with a continuum set of players and without side payments. This concept is an approximation of the core introduced by Weber, Shapley and Shubik. The weak-core is slightly larger than Aumann's α−core when adapted to large anonymous games. A non emptiness result is obtained based on the well known Scarf's non vacuity theorem for finite games.
