单词 | perfect equilibrium |
释义 | perfect equilibrium An equilibrium concept applicable to situations where decisions are made in two or more stages. At every stage all market participants choose whichever strategy is best for them, given the information they have to hand. At every stage but the last, decisions are taken on the assumptions, first, that market participants cannot now alter the decisions taken at earlier stages, even though new information may mean they now regret their previous decisions, and second, that all market participants will choose whatever is best for them at all subsequent stages. It is not consistent with perfect equilibrium to make threats which it would not pay one to carry out. |
