Quiz questions
Question 1
Which best captures the idea of "thinking strategically" as presented in the book?
- Focusing solely on maximizing your immediate payoff regardless of others
- Anticipating others' decisions and incorporating their incentives into your planning
- Relying only on intuition rather than formal analysis
- Always choosing the safest, risk-free option
Question 2
What defines a Nash equilibrium in a simultaneous-move game?
- A strategy profile where no player can unilaterally improve their payoff
- An outcome that maximizes total social welfare
- A strategy where players alternate moves to reach agreement
- A randomized strategy profile only
Question 3
Why do players use mixed strategies (randomization)?
- To conceal private information from rivals
- To make opponents indifferent and prevent exploitation when pure equilibria don't exist
- Because they are risk-averse and avoid deterministic actions
- To communicate intentions credibly
Question 4
What is backward induction used for in sequential games?
- To compute Nash equilibria of simultaneous games
- To reason from the end of the game backward to find subgame-perfect strategies
- To randomize actions to keep opponents guessing
- To design auctions
Question 5
How can cooperation be sustained in repeated interactions according to the book?
- By committing to a single action permanently
- Through strategies that reward cooperation and punish defection, leveraging reputation and the shadow of the future
- By ensuring all players have complete information about types
- By using auctions and bargaining mechanisms
