Introduction: Thinking Strategically
Thinking strategically means anticipating others' decisions and incorporating their incentives into your planning. It introduces game theory as a toolkit to analyze interactive decision problems in business and life, emphasizing strategic thinking over solitary optimization.
Supporting points
- Strategy depends on interdependent choices, not just individual payoffs.
- Predicting others' responses is essential to choosing effective actions.
- Games provide models to formalize conflicts and cooperation.

Introduction: Thinking Strategically
1. The Basics: Games, Payoffs, and Strategies
This chapter defines games formally by listing players, available strategies, and payoffs, and shows how to represent interactions in normal (matrix) and extensive form. It explains dominant strategies, dominated strategy elimination, and how payoffs reflect preferences and incentives.
Supporting points
- A game is specified by players, strategy sets, and payoff functions.
- Dominant strategies win regardless of opponents' moves; dominated strategies can be discarded.
- Normal

2. Simultaneous-Move Games and Nash Equilibrium
Simultaneous-move games are ones where players choose without knowing others' current choices; Nash equilibrium identifies strategy profiles where no player can unilaterally improve their payoff. The chapter explains existence, multiplicity, and interpretation of equilibria as stable predictions of play.
Supporting points
- Nash equilibrium: each player's strategy is a best response to others'.
- Games can have multiple equilibria or none in pure strategies, creating coordination or indeterminacy problems.
- Dominance

3. Mixed Strategies and Randomization
When pure-strategy equilibria don't exist or are exploitable, players may randomize over actions; mixed strategies assign probabilities to pure moves and can produce equilibrium. The chapter shows how randomization makes players unpredictable and balances opponents' incentives.
Supporting points
- Mixed strategy equilibrium exists in many games where no pure equilibrium exists.
- Indifference principle: opponents randomize so each action used yields equal expected payoff.
- Randomization can be strategic (e.g., in pricing, sports, auctions) to avoid being exploited.

4. Sequential Games and Backward Induction
Sequential games model situations with ordered moves and observed actions, using game trees to represent choices; backward induction solves these by reasoning from the end of the game to the beginning. Subgame perfect equilibrium refines Nash by requiring credible optimality in every subgame.
Supporting points
- Extensive
- form trees capture timing, information sets, and moves.
- Backward induction finds optimal strategies by solving later decisions first.

5. Commitment: Making Your Threats and Promises Credible
This chapter examines commitment devices that change future incentives and make threats or promises credible, altering opponents' expectations and behavior. It distinguishes endogenous commitment (actions you take now) from exogenous mechanisms and shows payoff trade-offs.
Supporting points
- Credible commitments change the game by restricting your future choices.
- Irreversible actions, contracts, reputation, and sunk costs can serve as commitment tools.
- Commitment can create first

6. Strategic Moves and Manipulating Choices
The chapter explores strategic moves—announcements, delegations, and actions—that influence rivals' choices by changing their payoff calculations. It covers preplay communication, framing choices, and mechanisms to shape the strategic landscape.
Supporting points
- Strategic moves alter opponents' incentives without changing their preferences directly.
- Cheap talk can sometimes coordinate but lacks credibility unless backed by action.
- Delegation, partial irreversibility, and changing the choice set can be used to influence rivals.

7. Information and Asymmetry: Signaling and Screening
This chapter addresses games with private information, where signaling (by informed players) and screening (by uninformed players) help reveal types. It explains separating and pooling equilibria and shows how information asymmetry shapes markets and contracts.
Supporting points
- Private information creates adverse selection and moral hazard problems.
- Signaling (education, warranties) can credibly convey high
- quality types if costly to mimic.
