Question 1

According to Adam Smith, which of the following best describes the relationship between self-interest and altruism in a successful society?

Accepted Answer

A balance between self-interest and altruism is necessary for a successful and just society.

Question 2

In the context of game theory, what does the Nash Equilibrium represent?

Accepted Answer

A stable outcome where no player can improve their payoff by unilaterally changing their strategy.

Question 3

Consider the following payoff conditions for two firms deciding between Technology A and Technology B:

$$\begin{align*}
&	ext{Profit1AB} \u003e 	ext{Profit1BB} \
&	ext{Profit1AA} \u003e 	ext{Profit1BA} \
&	ext{Profit2AB} \u003e 	ext{Profit2AA} \
&	ext{Profit2BB} \u003e 	ext{Profit2BA}
\end{align*}$$

What is the dominant strategy for Firm 2?

Accepted Answer

Firm 2 should always choose Technology B.

Question 4

Which real-world scenario best illustrates the concept of the Prisoner's Dilemma as discussed in the materials?

Accepted Answer

Countries engaging in an arms race, where mutual cooperation would be better but fear of exploitation leads to non-cooperation.

Question 5

Why might repeated interactions between players in a game lead to more cooperative outcomes?

Accepted Answer

Players can build reputations and enforce cooperation over time.

Question 6

Suppose Firm 1 and Firm 2 are choosing dashboard technologies. If Firm 1 chooses Technology A regardless of Firm 2's choice, what does this indicate about Firm 1's strategy?

Accepted Answer

Firm 1 has a dominant strategy to choose Technology A.

Question 7

Which of the following statements about self-interest and altruism is most consistent with the discussion of Adam Smith's philosophy?

Accepted Answer

Altruism and self-interest can overlap, as helping others can fulfill one's own psychological needs.

Question 8

In the context of digital platforms and social media, how does the Prisoner's Dilemma manifest according to the discussion?

Accepted Answer

Short-term incentives lead users to 'defect' by posting sensational or low-quality content, resulting in a race to the bottom.

Question 9

Which of the following best explains why Nash Equilibrium outcomes can be inefficient?

Accepted Answer

Players act rationally based on their own incentives, which can lead to stable but suboptimal outcomes for the group.

Question 10

Suppose two firms are considering whether to develop their own dashboard operating system or contract with a tech firm. If both firms choose their dominant strategies, what is the likely outcome?

Accepted Answer

Each firm will choose the strategy that maximizes its own profit, leading to a Nash Equilibrium.

Question 11

Which of the following is a key insight from game theory as applied to real-world policy challenges?

Accepted Answer

Strategic interactions can be redesigned by altering incentives and strengthening institutions to achieve better outcomes.

Question 12

If a player in a game has a dominant strategy, what does this mean?

Accepted Answer

The player will earn a higher payoff with this strategy, regardless of what others choose.

Question 13

Which of the following best describes the concept of 'mutually assured destruction' (MAD) as a Nash Equilibrium?

Accepted Answer

Both parties choose non-cooperative strategies, leading to a stable but undesirable outcome.

Question 14

How can institutions or regulations help move outcomes from inefficient equilibria to more socially optimal ones?

Accepted Answer

By enforcing rules that change incentives and encourage cooperation.

Question 15

Which of the following is an example of how self-interest can lead to altruistic outcomes, as discussed in the materials?

Accepted Answer

A person helps others because it fulfills their own psychological need for happiness and usefulness.

Question 16

Suppose two firms are locked in a strategic battle over dashboard technology. If Firm 1's dominant strategy is Technology A and Firm 2's is Technology B, what is the Nash Equilibrium?

Accepted Answer

Firm 1 chooses Technology A and Firm 2 chooses Technology B.

Question 17

Which of the following statements about stability and optimality in game theory is correct?

Accepted Answer

Stability does not guarantee optimality; stable outcomes can be inefficient.

Question 18

If a social media platform wants to encourage higher-quality content and avoid a 'race to the bottom,' which game-theoretic approach would be most effective?

Accepted Answer

Redesign incentives to reward cooperation and long-term engagement.

Question 19

Which of the following best describes why cooperation is difficult in one-shot Prisoner's Dilemma games?

Accepted Answer

Players cannot communicate and have no way to enforce agreements.

Question 20

Which of the following is NOT a reason why repeated games can lead to more cooperative outcomes?

Accepted Answer

Players always forget previous interactions and cannot learn from them.
