Webbdefinition, off-path actions are never observed in equilibrium, which raises the possibility that incorrect beliefs about off-path play might persist for quite some time. Following Fudenberg and Levine [15], we call a belief that is objectively false a “superstition.”2 There are two manifestations of the role of off-path superstitions. One ... WebbIN AN EXTENSIVE-FORM GAME, Nash equilibrium places no restriction on the behavior of players at information sets reached with probability zero. This gives rise to equilibria supported by unreasonable behavior off the equilibrium path. The general program of perfecting Nash equilibrium, initiated by Selten (1965,
WebbUnlike the above solution concepts, no player's strategy is strictly dominated beginning at any information set even if it is off the equilibrium path. Thus in PBE, players cannot threaten to play strategies that are strictly dominated beginning at any information set off the equilibrium path. Webbfigure, some equilibrium paths are shown for some values of the perturbation parameter ǫ To sum up, the equilibrium paths of this structure can have • a trivial equilibrium path and an asymmetric bifurcation point if ǫ = 2ϕ0. The secondary path is defined in equation (8). • A stable equilibrium path without critical points if ǫ > 2ϕ0 ...

Suppose 1 plays q 1 ≠ 64; f.i., he plays q 1 = 50. Then 2's best reply should be q 2 ∗ ( 50) = 425 whereas her plan is to play q 2 = 1000. So she is not best replying to 1's possible deviations.
