(Game theory)
Consider the (rather serious) stage game played between two countries depicted in the payoff matrix below. Country 2 War Peace Country 1 War 3,3 6,0 Peace 0,6 5,5 Assuming that the stage game is played an infinite/indefinite number of times (i) What is the PV of a player's payoff stream if both players play the NE actions of the stage game each time the game is played? 3 PV (ii) Suppose both players play a "Grim Trigger Strategy". Calculate the discount factor (b) that would allow both players playing "Peace" each time they play the game to "emerge" as a SPE path. 38 PV = -526+ *-* = PV , > 1-8 526(1-8) +3 8 = 6-68 +38 = 6-38 -1 2-38
