Game Theory and Strategy Prisoners’ Dilemma Game Column Silence Fink Silence -1 0 -10 Fink Row -1 0 -8 -8
Game Theory and Strategy Prisoners’ Dilemma Game Row Player: 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 -1 0 -10 0 -8 -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: Column Cooperate Fink 1 5 4 4 -1 Fink Row Cooperate 9 0 0
Game Theory and Strategy A cooperative game with conflict Game with multiple (two) Nash equilibria Prize Fight Ballet Man Woman Prize Fight Ballet 1 2 -1 -1 -5 -5 2 1
Game Theory and Strategy Suppose this game were played sequentially? Would it be better to go first or second? Prize Fight Ballet Man Woman Prize Fight Ballet 1 2 -1 -1 -5 -5 2 1
Game Theory and Strategy Would you want to move first or second? Prize Fight Ballet Man Woman Prize Fight Ballet 20 10 100 6 90 4 30 8

Game Theory and Strategy Lessons #1: 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.
