Example
Consider the game
Ben | |||
---|---|---|---|
Anna |
Help | Leave | |
Help | 3, 2 | 0, 0 | |
Leave | 0, 0 | 2, 1 |
Anna can help or leave the village. Ben can also either help of leave a village attacked by zombies.
In equilibrium:
- Anna plays a best response to Ben's strategy.
- Ben plays a best response to Anna's strategy.
Here, they reach an equilibrium when they take the same action.
Ben | |||
---|---|---|---|
Anna |
Help | Leave | |
Help | 2, 1 | 0, 0 | |
Leave | 0, 0 | 3, 2 |
(Help, Help) is an equilibrium. (Leave, Leave) is an equilibrium too!
Question
Consider the following payoff matrix:
Ben | |||
---|---|---|---|
Anna |
Help | Leave | |
Help | 64, 61 | 25, -54 | |
Leave | -86, -75 | -29, 47 |
What is the equilibrium(s) of the game above?
The equilibrium is (Help, Help)
