The sub-game perfection in period 2 needs the play of the only Nash equilibrium of the stage game. Because there is one exactly Nash equilibrium for the stage game, thus in period 2 the selection of the Nash equilibrium to be played would not impact the incentives in period 1. Therefore, the only sub-game perfect equilibrium would be the play of Nash equilibrium for the stage game in both the periods. If there is any infinite T, the logic from the two-period case would be applicable, and the answer remains the same.

There is no discounting in this problem and so a player’s payoff
in this repeated game is the sum of her payoffs in the two plays of
the stage game.

Exercise 3: In class we discussed the Nash Equilibrium solution concept and how it is useful to eliminate non-rational behavior, but with the disadvantage of not necessarily leading to a unique solution. One possible refinement that can be considered is the following: "If more than one Nash Equilibrium exist, but one of them makes every player better off than under the other Nash Equilibria, then surely that is the Nash Equilibrium that will be played." Consider playing the following simultaneous...
