This chapter reviews recent experimental data testing game theory and behavioral models that have been inspired to explain those data. The models fall into four groups: in cognitive hierarchy or level- k models, the assumption of equilibrium is relaxed by assuming agents have beliefs about other...

We study a model where agents face a continuum of two-player games and categorize them into a finite number of situations to make sense of their complex environment. Agents need not share the same categorization. Each agent can cooperate or defect, conditional on the perceived category. The...

This study examines how each player chooses her/his optimal action in "normal-form games with unawareness" by applying a "discovery process" to them. We show that if each player implements a best response to the opponents' immediately preceding plays, then any discovery process converges to a...
