Prisoners’ Dilemma Game
Row Player: Dominant Strategy: Fink
Column Player: Dominant Strategy: Fink
Dominant Strategy (Nash) Equilibrium: (-8, -8)
Note: It is a dilemma since if they both cooperated by remaining silent: (-1, -1).

Game Theory and Strategy
The Prisoners’ Dilemma Game can occur in many contexts:
What is best for an individual may not be best for a division;
What is best for a division may not be best for a firm;
What is best for a firm many not be best for an industry;
What is best for an industry may not be best for a nation; and
What is best for a nation may not be best for the world.
Game Theory and Strategy
Now that we have learned the concept of dominant
strategy equilibrium, there is a second important
equilibrium concept called a Nash equilibrium.
Note: All dominant strategy equilibrium are
Nash equilibrium, but not all Nash equilibrium
are dominant strategy equilibrium.
Game Theory and Strategy
Game with no dominant strategy equilibrium, but a Game
with one Nash equilibrium:R

Game Theory and Strategy:
Lessons #1
1. Commitment (sunk costs) can be
used to achieve competitive advantage.
• Preemption strategy
• Note: It is important to communicate
the commitment to competitors.

Lessons #2:
2. Commitment (sunk costs) can be used to achieve cooperation.
The importance of mutual economic hostages: The wise manager should think beyond Machiavelli’s myopic approach to contracting and should seek both to give and receive credible (sunk cost) commitments that facilitate ongoing relationships and adaptation.
