The existence of TU -core in normal form games

This paper provides a TU -core existence result in a large class of normal form games. In the oligopoly markets of a homogeneous good, the TU -core is non-empty if all profit functions are continuous and concave. In a general game, the existence of TU -core follows from the weak separability, the compactness and convexity of choice sets, and the concavity and continuity of payoff functions.
