Looking at the game matrix and solving by the standard Nash equilibrium rules, we can see that Y strictly dominates X for both the players. Thus SPNE is (Y,Y) and payoff to each player is 1.
If instead we consider an infinitely repeated game with a
discount factor and average it
to 5,we get:
This is because discounted present value of any investment is given as -
where PV = present value, FV = future value, r = discount rate and
n = no. of years.
Considering infinitely repeated game, the right side forms a GP.
Sum of infinite GP =
where a = 1 and r =
in our case.
Thus Sum =

Consider the infinitely repeated version of the symmetric
two-player stage game in figure PR 13.2. The first number in a cell
is player 1's single-period payoff. Assume that past actions are
common knowledge. Each player's payoff is the present value of the
stream of single-period payoffs where the discount factor is d. (a)
