Consider the following payoff matrix: Player 2 b1 b2 b3 a1 10, 10 2, 12 (0, 13 Player 1 a2 12, 2 (5, 5) (0,0 a3 13, 0 (0,0) (1, 1 ) Now, consider a game in which the above simultaneous game are played twice. Also, players can observe the actions chosen in the first round before they play the second round. Find the NE in this stage game. Also, try to list some SPNE in which the stage game NE is NOT chosen is the first round
