The crucial difference from the classical “solution-concept” analysis of a game is that epistemic game theory takes a bottom-up perspective. Once the context of the game is specified, the rational outcomes are derived, given assumptions about how the players are making their choices and what they know and believe about how the others are choosing. In the remainder of this section, we briefly discuss some general issues that arise from taking an epistemic perspective on games. We postpone discussion of higher-order and strategic uncertainty until Sections 3, 4 and 5.
