E: Exercises [7 exercises]. S: Solutions to exercises. Weak Sequential Equilibrium Thus, simply requiring that each player have a belief and act optimally given this belief suffices to eliminate the implausible equilibrium R,R'.
Requirements 1 and 2 insist that the players have beliefs and act optimally given these beliefs, but not that these beliefs be reasonable. As a second hypothetical illustration of Requirement 3, suppose that in the game above there was a mixed strategy equilibrium in which player 1 plays L with probability q1, M with probability q2, and R with probability 1-q1-q2.
Requirements 1 through 3 capture the essence of a perfect Bayesian equilibrium. The crucial new feature of this equilibrium concept is due to Kreps and Wilson : beliefs are elevated to the level of importance of strategies in the definition of equilibrium. Formally an equilibrium no longer consists of just a strategy for each player but now also includes a belief for each player at each information set at which the player has the move.
Finally, a perfect Bayesian equilibrium consists of strategies and beliefs satisfying requirements 1 through 4. Password: Forgot password? Printer Friendly. Dynamic Games of Incomplete Information.
