Challenging Standard Non-Cooperative Game Theory? From Bacharach's "Variable Frame Theory" to "Team Reasoning"

The paper purports to stress how the two major contributions of Bacharach: "Variable Frame Theory" (VFT) and "Team Reasoning" (TR) improve Standard Non-Cooperative Game Theory in some relevant aspects which I point out. The aims are to show: (i) how Bacharach respectively justifies coordination and cooperation within these theories, and (ii) how these improvements in both VFT and TR involve a new conception of players and their rationality. I underline how coordination and cooperation rely on contextual and social determinants, which challenge and even contradict some pillars of standard individual rationality in terms of subjective expected utility, in games. Even if Bacharach's conceptual and methodological choices within these theories induce numerous difficulties, I try to show that Bacharach’s work underlines some of the implications and related problems induced by the mere foundations of standard non-cooperation game theory.
