Knowledge check
Q1. What is the main focus of Game Theory?
- A. To study the behavior of individuals in isolation
- B. To analyze decision-making in strategic situations ✓
- C. To predict the weather
- D. To improve mathematical calculations
Why: Game Theory primarily focuses on how individuals or groups make decisions when their outcomes depend on the actions of others.

- A. A solo puzzle game
- B. A chess match between two players ✓
- C. A library book checkout system
- D. A calculator performing arithmetic
Why: A chess match is a strategic interaction between two players, making it a classic example of a game in Game Theory.

- A. A reward given to players for participating
- B. The outcome or result of a player's decision ✓
- C. A penalty for losing a game
- D. A tool used to calculate probabilities
Why: A 'payoff' refers to the outcome or result that a player receives based on the decisions made by all participants in the game.

- A. A random guess made by a player
- B. A plan of action a player takes to achieve their objective ✓
- C. A rule set for a video game
- D. A type of mathematical equation
Why: A strategy is a plan of action that a player follows to achieve their goals, considering the possible actions of other players.

Module 3: The Prisoner's Dilemma in Real Life
The Prisoner's Dilemma in Real Life
Knowledge check
Q1. What is the main conflict in the Prisoner's Dilemma?
- A. One player benefits while the other loses
- B. Both players would be better off if they cooperate but may end up worse off if they act in self-interest ✓
- C. One player has complete control over the outcome
- D. The outcome is always fair and predictable
Why: The dilemma arises because individual rationality leads to a worse collective outcome, even though cooperation would yield better results for both players.
Q2. Which of the following is a real-life example of the Prisoner's Dilemma?
- A. A competition between two companies on pricing strategies ✓
- B. A person choosing between two different brands of soda
- C. A family deciding where to go on vacation
- D. A student choosing between studying or playing video games
Why: In competitive pricing, both companies would benefit from higher prices, but each has an incentive to lower prices to gain more customers, leading to lower profits for both.
Q3. What is the dominant strategy in the Prisoner's Dilemma?
- A. Cooperate
- B. Defect ✓
- C. Randomly choose
- D. Wait for the other player to decide
Why: Defecting is the dominant strategy because it always results in a better individual outcome, regardless of the other player's choice.
Q4. In the Prisoner's Dilemma, if both players cooperate, what is the outcome?
- A. Both receive the maximum punishment
- B. Both receive a moderate punishment
- C. One player is rewarded while the other is punished
- D. Both are rewarded with the best possible outcome ✓
Why: Cooperation leads to the best collective outcome, where both players receive the best possible result.
Q5. How can the Prisoner's Dilemma be resolved in real life?
- A. By ignoring the other player's actions
- B. By creating mechanisms that encourage cooperation, such as repeated interactions or rewards ✓
- C. By always choosing to defect
- D. By making the consequences of cooperation more severe
Why: Repeated interactions or incentives that promote cooperation can help overcome the dilemma and lead to better collective outcomes.

Module 4: Nash Equilibrium and Everyday Choices
Nash Equilibrium and Everyday Choices
Knowledge check
Q1. What is a Nash Equilibrium?
- A. A situation where all players are trying to change their strategy
- B. A situation where no player can benefit by changing their strategy while the others keep theirs unchanged ✓
- C. A situation where only one player has an optimal strategy
- D. A situation where all players are cooperating to maximize overall benefit
Why: Because in a Nash Equilibrium, each player's strategy is optimal given the strategies of the others, and no one has an incentive to deviate
Q2. In the Prisoner's Dilemma, what is the Nash Equilibrium?
- A. Both players cooperate
- B. Both players defect ✓
- C. One player cooperates and the other defects
- D. There is no Nash Equilibrium
Why: Because both players defecting is the outcome where neither can benefit by changing their strategy unilaterally
Q3. Which of the following is a real-life example of a Nash Equilibrium?
- A. Two friends choosing different restaurants to avoid meeting each other ✓
- B. Two companies setting prices lower than their competitors
- C. Two drivers both choosing the same route to avoid traffic
- D. Two countries engaging in an arms race
Why: Because neither friend can benefit by changing their choice if the other stays the same, making it a stable outcome
Q4. What happens if a game has multiple Nash Equilibria?
- A. Players will always choose the same equilibrium
- B. Players may choose any of the equilibria depending on the situation ✓
- C. The game becomes unsolvable
- D. There is no Nash Equilibrium
Why: Because players may coordinate or follow certain conventions to select one equilibrium over others
Q5. In a Nash Equilibrium, what is true about the players' strategies?
- A. They are not aware of each other's strategies
- B. They are trying to maximize their own benefit regardless of others
- C. They are trying to minimize the benefit of others
- D. They are choosing strategies that are optimal given the strategies of others ✓
Why: Because in a Nash Equilibrium, each player's strategy is optimal given the strategies of the other players

Cooperation vs. Competition
Knowledge check
Q1. What is a key factor that encourages cooperation in a group?
- A. High competition
- B. Shared goals ✓
- C. Individual rewards
- D. Lack of communication
Why: Shared goals create a sense of unity and mutual benefit, which encourages cooperation among group members.
Q2. Which of the following is an example of a cooperative strategy in game theory?
- A. Prisoner's Dilemma
- B. Chicken Game
- C. Stag Hunt ✓
- D. Battle of the Sexes
Why: The Stag Hunt represents a scenario where cooperation leads to a better outcome for all players involved.
Q3. In a competitive situation, what is the primary focus of individuals?
- A. Mutual benefit
- B. Personal gain ✓
- C. Team success
- D. Long-term relationships

- A. Decreased trust
- B. Increased conflict
- C. Sustainable relationships ✓
- D. Short-term gains
Why: Cooperation in repeated interactions often leads to sustainable relationships as trust and mutual benefit are reinforced over time.

Applying Game Theory to Personal Finance
Knowledge check
Q1. What is the primary goal of using game theory in personal finance?
- A. To maximize short-term gains
- B. To make better decisions under uncertainty ✓
- C. To eliminate all risks
- D. To outsmart others in investing

- B. A loan agreement between two parties ✓
- C. Buying a life insurance policy
- D. Saving money in a bank account
Why: In a loan agreement, one party's gain (borrower) is another's loss (lender), making it a zero-sum game.
Q3. When making investment decisions, what does game theory suggest about considering other players' strategies?
- A. Ignore them, as they do not affect your decisions
- B. Assume they will act in your best interest
- C. Anticipate their actions and plan accordingly ✓
- D. Always follow the majority
Why: Game theory emphasizes anticipating others' strategies to make optimal decisions, which is important in competitive markets.

- A. Nash Equilibrium ✓
- B. Prisoner's Dilemma
- C. Dominant Strategy
- D. Zero-Sum Game
Why: Nash Equilibrium helps in understanding stable outcomes where no player has an incentive to deviate, which is useful in evaluating investment choices.
