10/(1+ δ)
... For both players to prefer alternating equilibrium strategies, both 10/(1- δ2) and δ[10/(1- δ2)] must be greater than 3/(1- δ). Since the discount factor is a number between zero and one, 10/(1- δ2) > δ[10/(1- δ2)], and so if δ[10/(1- δ2)] > 3/(1- δ), then 3/(1- δ) > 10/(1- δ2), so, for both players ...

... (If p1 > p2 , then 1 − p1 < 1 − p2 , and p1 /(1 − p1 ) > p2 /(1 − p2 ).) Hence player 1’s payoff is p21 q + (1 − p1 )2 (1 − q). Again, to make it irrelevant what Player 2 plays, it needs to be the case that p21 = (1 − p1 )2 . It follows that p1 = 1/2. Hence, the player’s payoff from the behavioral s ...
