📝 Homework 3 – Nash Equilibrium

Question 1

Juan and Elsa are two of ten players who are participating in a reality TV show that makes players engage in a series of challenges. If a player loses that challenge they are sent home and lose the opportunity for the grand prize. In previous episodes, they have each won a medallion that gives the holder immunity from a challenge that sends them home. However, a player must decide to use it before the challenge starts.

Juan and Elsa have both won immunity medallions and are now facing each other in a challenge that may send one of them home, or someone else could lose the challenge and be sent home. They can use their immunity now or save it for later.

The payoffs to their strategies are given in the payoff matrix shown below. The first entry represents Elsa’s payoff and the second entry represents Juan’s payoff.

How many Nash equilibria exist for this game?
