On coordination in non-cooperative game theory : Explaining how and why an equilibrium occurs and prevails

Abstract : Our thesis proposes to change the ontology and methodology of game theory, appraising games as the understanding of the players’ strategic reasoning process. Our contribution is based on an interdisciplinary approach for a reassessment of the kind of intersubjectivity involved in strategic reasoning. We claim that the analysis of games should involve the study and the determination of the reasoning process that lead the players to a specific outcome, i.e. to a specific solution. A game should not be understood, like in standard game theory, as a mathematical representation of an individual choice at the equilibrium. This requires investigating the players’ capacity of coordination. We assert that understanding the process of coordination allows understanding strategic reasoning and ultimately to provide new answers to the indeterminacy problem of game theory which is one of the stalemates that game theory faces and which underscores its positive and normative difficulties. The thesis is grounded on the argument that understanding the players’ reasoning process in games necessitates first and foremost to explain how the players form their beliefs regarding each other’s choices, but also each other‘s perceptions and beliefs and reasoning processes in a strategic context. One of the purposes of the thesis is to show that a psychological theory explaining the formation of players’ beliefs is required to account for coordination, and that the Theory of Mind (ToM) offers such adequate psychological framework. We suggest building an alternative theory of games based on the simulation theory as such theory of mind. We then specify an axiomatic characterization of rational choices in games in the presence of players able to simulate the reasoning of others.
