Non-equilibrium game theory.

Without equilibria, how do you decide what kind of agents to talk about? Random agents?

I think you want some kind of rational agent constraint, still; recursive "common knowledge of rationality", even. Just refuse to accept arbitrary equilibria.

Maybe accept unique equilibria when they exist. To first approximation, the idea is that agents are uncertain about what equilibrium they're in if there are several. This has obvious problems -- they're not in any equilibrium then, so why do they think they may be?

What does it mean to have common knowledge that all players are "rational" without knowing what function they implement?
