Power Point Set 9c: Game Theory and Strategy
Game Theory and Strategy • Key Concept: Preemption of Strategically Valuable Assets • Access to raw materials (e.g., Alcoa) • Wal-mart’s rural strategy
Analyzing Competitive Dynamics Commitment Vs. Flexibility • Commitment • Game-theoretic preemption strategy • Flexibility • Real (Strategic) Options Analysis

Column Silence Fink -1 0 -1 Silence -10 Row -10 -8 Fink 0 -8 Game Theory and Strategy • Prisoners’ Dilemma Game
-1 0 -1 -10 -10 -8 0 -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).
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: • 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.

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