Game Theory: Basic Ideas
In this introductory talk, I will present the basic ideas of modelling interaction situations using game theory. I will introduce concepts needed to understand static games of complete and perfect information. In particular, I will discuss the notions of strategy, preference and utility, and present standard solution concepts like Nash equilibria. I will illustrate the use of game-theoretical concepts in the analysis of social phenomena like conventions. I will present some well known games such as Prisoner's Dilemma (PD) and Hi-Lo, and discuss the challenges they have been argued to raise to the individualistic presuppositions of game theory.

Team Reasoning Approach to the We
In this talk, I will present team reasoning, which is an approach to decision making that has been suggested as an alternative to standard game-theoretical approaches. In team-reasoning, an agent acts as a member of a larger group by choosing her strategy as her part in the group's action. I will present the ideas of preference transformation and agency transformation, and illustrate their effects in games like PD and Hi-Lo. I will discuss the notion of group preference that seems to be presupposed by team reasoning, and I will consider two alternative ways of conceiving the relationship between team reasoning and collective intentionality.
