We define weak and strong rationality of players in terms of dominance
rather than expectation with respect to probabilistic beliefs. We also
define certain subsets of strategy profiles as weak or strong non-probabilistic
correlated equilibrium, analogously to correlated equilibrium. It is shown that
the set of profiles played when there is common knowledge of weak or strong
rationality is a weak or strong non-probabilistic correlated equilibrium, correspondingly.
The largest weak non-probabilistic correlated equilibrium is the
set of profiles that survive iterated elimination of strictly dominated strategies.
Rationality can be strengthened for games with perfect information by
considering rationality in subgames. A player is substantively rational if she is
rational in all subgames, and materially rational if she rational in subgames at
vertices that are reached. Aumann (1995, 1998) introduced and studied these
two notions for the case of weak rationality. We characterize the weak and the
strong versions of these notions of rationality in terms of non-probabilistic correlated
equilibria. We show that non-probabilistic correlated equilibria can be
also characterized in terms of non-probabilistic belief rather than knowledge.
