Resum:
We analyze which normal form solution concepts capture the notion of
forward induction, as defined by van Damme (JET, 1989) in the class
of generic two player normal form games preceded by an outside
option. We find that none of the known strategic stability concepts
(including Mertens stable sets and hyperstable sets) captures this
form of forward induction. On the other hand, we show that the
evolutionary concept of EES set (Swinkels, JET, 1992) is always
consistent with forward induction.
