I SEE THAT SOME PEOPLE SAY A, AND OTHERS SAY C. WHICH ONE IS CORRECT, OR ARE THEY BOTH CORRECT?
Homework Answers
Option C.
The above mentioned game does not have an equilibrium in pure strategy. Because in all the cases, the another person has an incentive to deviate from the strategy. Since there is no equilibrium in pure strategy, the game will have equilibrium in mixed strategy.Thus, there is mixed strategy equilibrium in the game.
