Game Theory and Strategy Prisoners’ Dilemma Game Row Silence Fink Column -1 -10 -8

Game Theory and Strategy 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). -1 -10 -8

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: Row Cooperate Fink Column 5 4 1 9 -1

Game Theory and Strategy A cooperative game with conflict Game with multiple (two) Nash equilibria Man Prize Fight Ballet Woman 2 -1 1 -5

Game Theory and Strategy Suppose this game were played sequentially? Would it be better to go first or second? Man Prize Fight Ballet Woman 2 -1 1 -5

Game Theory and Strategy Would you want to move first or second? Man Prize Fight Ballet Woman 10 100 20 4 90 30 8 6

How Can “Commitment” Affect A Competitor’s Response? Commitment = An Irreversible Action (Sunk Costs) Competition In The Commercial Aircraft Industry Airbus No Launch Launch Boeing 400 300 200 -100 -200

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.

How Can “Commitment” Affect A Competitor’s Response? Commitment = An Irreversible Action (Sunk Costs) GM Cooperate L. Race Toyota 112 123 -28 58 91 -51

How Can “Commitment” Affect A Competitor’s Response? Mutual sunk cost commitments GM Cooperate L. Race Toyota 112 -28 58 -51

Game Theory and Strategy 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.
