Rationalizability in large games (Q2447150)

This paper gives a formal description and characterization of so-called rationality, that is, common knowledge of rationality of the agents, in games with a continuum of players. The task is central as many papers now use a continuum of players in order to prevent misrepresentation of many economic environments where a finite number of players is simply insufficient. In such games with a large number of players, each agent is ``strategically negligible''. What I found interesting in the paper is the characterization of Nash equilibria in large games and their relation to the rationalization.
