Generic extensive form games of perfect information have a unique subgame perfect equilibrium. Nöldeke and Samuelson (1993) show that in a stochastic evolutionary model also non-subgame perfect equilibriumstrategies may well survive in the long run. In a different model of evolution in the agent normal form of generic extensive form games of perfect information Hart (2002) shows that under suit...

The foundations of incomplete contracts have been questioned using or extending the subgame perfect implementation approach of Moore and Repullo (1988). We consider the robustness of subgame perfect implementation to the introduction of small amounts of asymmetric information. We show that Moore-Repullo mechanisms may not yield (even approximately) truthful revelation in pure or totally mixed s...
