a. For what values of a is (October, October) a dominant strategy equilibrium —i.e. a Nash equilibrium reached through iterated elimination of dominated strategies? b. For what values of a is (March, March) a dominant strategy equilibrium? c. Find the (pure strategy) Nash equilibria of the game as a function of parameter a? Explain your answer.
