In the Prisoner's Dilemma, what is the dominant strategy for each player?

  1. Confess

  2. Remain Silent

  3. Cooperate

  4. Defect


Correct Option: A
Explanation:

In the Prisoner's Dilemma, the dominant strategy for each player is to confess, regardless of the other player's choice.

What is the Nash Equilibrium in the Prisoner's Dilemma?

  1. (Confess, Confess)

  2. (Remain Silent, Remain Silent)

  3. (Cooperate, Cooperate)

  4. (Defect, Defect)


Correct Option: A
Explanation:

The Nash Equilibrium in the Prisoner's Dilemma is the outcome where both players choose to confess, even though they would both be better off if they both chose to remain silent.

What is the Pareto Efficient outcome in the Prisoner's Dilemma?

  1. (Confess, Confess)

  2. (Remain Silent, Remain Silent)

  3. (Cooperate, Cooperate)

  4. (Defect, Defect)


Correct Option: C
Explanation:

The Pareto Efficient outcome in the Prisoner's Dilemma is the outcome where both players choose to cooperate, as this outcome maximizes the total payoff for both players.

What is the main reason why players in the Prisoner's Dilemma often choose to confess, even though it is not in their best interest?

  1. Fear of retaliation

  2. Lack of trust

  3. Miscommunication

  4. All of the above


Correct Option: D
Explanation:

Players in the Prisoner's Dilemma often choose to confess due to a combination of fear of retaliation, lack of trust, and miscommunication.

What are some strategies that can be used to promote cooperation in the Prisoner's Dilemma?

  1. Communication

  2. Repeated play

  3. Reputation building

  4. All of the above


Correct Option: D
Explanation:

Communication, repeated play, and reputation building are all strategies that can be used to promote cooperation in the Prisoner's Dilemma.

Which of the following is an example of a real-world situation that can be modeled using the Prisoner's Dilemma?

  1. Two firms competing for market share

  2. Two countries negotiating a peace treaty

  3. Two prisoners deciding whether to confess or remain silent

  4. All of the above


Correct Option: D
Explanation:

The Prisoner's Dilemma can be used to model a variety of real-world situations where two parties have conflicting interests and must decide whether to cooperate or defect.

What is the main lesson that can be learned from the Prisoner's Dilemma?

  1. Cooperation is always the best strategy.

  2. Defection is always the best strategy.

  3. The best strategy depends on the specific situation.

  4. There is no way to avoid conflict in a Prisoner's Dilemma situation.


Correct Option: C
Explanation:

The best strategy in a Prisoner's Dilemma situation depends on a variety of factors, including the payoffs, the level of trust between the players, and the likelihood of repeated play.

In the Prisoner's Dilemma, what is the payoff for each player if they both cooperate?

  1. R, R

  2. P, P

  3. S, S

  4. T, T


Correct Option: A
Explanation:

In the Prisoner's Dilemma, the payoff for each player if they both cooperate is (R, R), where R is the reward for cooperation.

In the Prisoner's Dilemma, what is the payoff for each player if they both defect?

  1. R, R

  2. P, P

  3. S, S

  4. T, T


Correct Option: B
Explanation:

In the Prisoner's Dilemma, the payoff for each player if they both defect is (P, P), where P is the punishment for defection.

In the Prisoner's Dilemma, what is the payoff for each player if one cooperates and the other defects?

  1. R, R

  2. P, P

  3. S, S

  4. T, T


Correct Option:
Explanation:

In the Prisoner's Dilemma, the payoff for the player who cooperates while the other player defects is (S, T), where S is the sucker's payoff and T is the temptation to defect.

What is the difference between a dominant strategy and a Nash Equilibrium?

  1. A dominant strategy is always a Nash Equilibrium, but a Nash Equilibrium is not always a dominant strategy.

  2. A Nash Equilibrium is always a dominant strategy, but a dominant strategy is not always a Nash Equilibrium.

  3. A dominant strategy and a Nash Equilibrium are the same thing.

  4. None of the above.


Correct Option: A
Explanation:

A dominant strategy is a strategy that is always the best response to any strategy that the other player might choose. A Nash Equilibrium is a set of strategies, one for each player, such that no player has an incentive to change their strategy given the strategies of the other players.

Can the Prisoner's Dilemma be solved by communication between the players?

  1. Yes

  2. No

  3. It depends on the specific situation.

  4. None of the above.


Correct Option: A
Explanation:

The Prisoner's Dilemma can be solved by communication between the players if they are able to reach a binding agreement to cooperate. However, this is often difficult to achieve in practice.

What is the role of trust in the Prisoner's Dilemma?

  1. Trust is essential for cooperation.

  2. Trust is not important in the Prisoner's Dilemma.

  3. Trust is only important if the players are playing the game repeatedly.

  4. None of the above.


Correct Option: A
Explanation:

Trust is essential for cooperation in the Prisoner's Dilemma because it allows the players to believe that the other player will not defect, even if it is in their best interest to do so.

Can the Prisoner's Dilemma be used to model real-world situations?

  1. Yes

  2. No

  3. It depends on the specific situation.

  4. None of the above.


Correct Option: A
Explanation:

The Prisoner's Dilemma can be used to model a variety of real-world situations, such as competition between firms, negotiations between countries, and interactions between individuals.

What are some of the limitations of the Prisoner's Dilemma as a model of real-world interactions?

  1. The Prisoner's Dilemma assumes that the players are rational and self-interested.

  2. The Prisoner's Dilemma does not take into account the possibility of communication between the players.

  3. The Prisoner's Dilemma does not take into account the possibility of repeated play.

  4. All of the above.


Correct Option: D
Explanation:

The Prisoner's Dilemma is a simplified model of real-world interactions, and it does not take into account all of the factors that can influence the behavior of players in real-world situations.
