why the credibility problems that arise in th enon-subgame-perfect equilibria.?

Question

thx for those people who ans this question

Answer 1

If you meant, non-subgame perfect equilibria I think I can help. I think your e and n ran together.

Non-subgame perfect equilibria suffer from a number of potential problems. First, they may be unreachable. It is possible to have Nash equilibria which cannot be reached by the players. It would be an optimum to play, but no one can play it. Secondly, there may be too many Nash equilibriums for the potential solution set to be useful. Subgame perfect solutions are a subset of the Nash solutions and so are easier in most cases to manage.
