2) Which of the following is true of Nash equilibrium?
A) A game can have only one Nash equilibrium.
B) No player can improve his payoff by changing his strategy once in Nash equilibrium.
C) A Nash equilibrium cannot occur if each player is aware of the strategies of other players.
D) A Nash equilibrium occurs if each player earns a zero payoff irrespective of the strategy he chooses.

C) $4 million
D) $3 million
Two rival firms have to choose between two strategies to maximize their benefits. The two alternative strategies available are X and Y. The matrix below shows their respective payoffs for each strategy they choose. The first number listed in each cell is the payoff to the row player and the second number listed is the payoff to the column player.
8) Refer to the scenario above. Which of the following is true in this case?
A) Firm A’s dominant strategy is to choose Strategy X.
B) Firm B’s dominant strategy is to choose Strategy Y.
C) Firm A chooses Strategy X if Firm B chooses Strategy Y.
D) Firm A chooses Strategy Y if Firm B chooses Strategy Y.
9) Refer to the scenario above. This game ________.
A) has two Nash equilibria
B) has a unique Nash equilibrium
C) has a dominant strategy equilibrium
D) does not have a Nash equilibrium
10) Refer to the scenario above. What is the sum of the payoffs to the firms if both the firms choose Strategy X?
