In a game theory context, what is a Nash Equilibrium?

  1. An outcome where no player can improve their payoff by unilaterally changing their strategy.

  2. An outcome where all players are making optimal choices.

  3. An outcome where the total payoff of all players is maximized.

  4. An outcome where the game is in a state of perfect competition.


Correct Option: A
Explanation:

A Nash Equilibrium is a set of strategies, one for each player, such that no player can improve their payoff by unilaterally changing their strategy while the other players keep their strategies unchanged.

What is the primary objective of experimental economics?

  1. To test and validate economic theories in a controlled environment.

  2. To analyze the behavior of individuals in economic decision-making scenarios.

  3. To develop new economic models and theories based on empirical data.

  4. To provide policy recommendations to governments and organizations.


Correct Option: A
Explanation:

Experimental economics aims to test and validate economic theories by conducting controlled experiments in which participants make economic decisions under specific conditions.

Which of the following is an example of a game with a dominant strategy?

  1. Prisoner's Dilemma

  2. Chicken Game

  3. Battle of the Sexes

  4. Matching Pennies


Correct Option: D
Explanation:

In Matching Pennies, each player has a dominant strategy of playing Heads or Tails, regardless of the other player's choice. This is because each player has an equal chance of winning or losing, regardless of their choice.

What is the main purpose of conducting laboratory experiments in experimental economics?

  1. To observe and analyze individual decision-making in controlled settings.

  2. To simulate real-world economic scenarios and study their outcomes.

  3. To test the validity of economic theories and models under specific conditions.

  4. To provide training and education in experimental economic methods.


Correct Option: A
Explanation:

Laboratory experiments in experimental economics allow researchers to observe and analyze individual decision-making in controlled settings, where they can manipulate variables and study the effects on economic outcomes.

In a sequential game, what is the concept of backward induction?

  1. Reasoning backward from the end of the game to determine optimal strategies.

  2. Considering all possible outcomes and choosing the strategy with the highest expected payoff.

  3. Analyzing the game tree and identifying dominant strategies for each player.

  4. Applying game theory principles to real-world economic scenarios.


Correct Option: A
Explanation:

Backward induction involves reasoning backward from the end of the game, considering the payoffs and available actions at each stage, to determine the optimal strategies for each player.

Which of the following is a common method used in experimental economics to elicit preferences from participants?

  1. Direct questioning

  2. Choice experiments

  3. Auctions

  4. Laboratory experiments


Correct Option: B
Explanation:

Choice experiments are a widely used method in experimental economics to elicit preferences from participants. They involve presenting participants with a series of hypothetical scenarios and asking them to make choices between different options.

In a game theory context, what is a zero-sum game?

  1. A game where the total payoff of all players is always zero.

  2. A game where one player's gain is always another player's loss.

  3. A game where the payoffs of all players are independent of each other.

  4. A game where all players have the same strategies and payoffs.


Correct Option: B
Explanation:

A zero-sum game is a game where the total payoff of all players is always zero, meaning that one player's gain is always another player's loss.

What is the main challenge in conducting field experiments in experimental economics?

  1. Controlling for external factors that may influence the results.

  2. Recruiting a large and diverse sample of participants.

  3. Designing experiments that are both realistic and ethical.

  4. Interpreting the results and generalizing them to real-world settings.


Correct Option: A
Explanation:

The main challenge in conducting field experiments in experimental economics is controlling for external factors that may influence the results, such as unobserved variables, confounding factors, and real-world complexities.

In a game theory context, what is a mixed strategy?

  1. A strategy where a player randomly chooses between multiple pure strategies.

  2. A strategy where a player always chooses the same pure strategy.

  3. A strategy where a player chooses a pure strategy based on the other player's strategy.

  4. A strategy where a player chooses a pure strategy based on their own preferences.


Correct Option: A
Explanation:

A mixed strategy is a strategy where a player randomly chooses between multiple pure strategies, with each pure strategy having a specified probability of being chosen.

What is the purpose of using control groups in experimental economics?

  1. To compare the results of an experiment to a baseline scenario.

  2. To ensure that the results of an experiment are not due to chance.

  3. To test the validity of a new economic theory or model.

  4. To provide a benchmark for evaluating the effectiveness of an economic policy.


Correct Option: A
Explanation:

Control groups are used in experimental economics to compare the results of an experiment to a baseline scenario, where the treatment or intervention is not applied, in order to determine the causal effect of the treatment.

Which of the following is an example of a non-cooperative game?

  1. Prisoner's Dilemma

  2. Chicken Game

  3. Battle of the Sexes

  4. Matching Pennies


Correct Option: A
Explanation:

The Prisoner's Dilemma is an example of a non-cooperative game, where each player's best strategy depends on the strategy of the other player, and there is no incentive for cooperation.

What is the concept of subgame perfection in game theory?

  1. A refinement of the Nash Equilibrium concept that eliminates strategies that are not credible.

  2. A method for finding the optimal strategy for a player in a game.

  3. A way to determine the outcome of a game when players have incomplete information.

  4. A technique for analyzing games with multiple stages or rounds.


Correct Option: A
Explanation:

Subgame perfection is a refinement of the Nash Equilibrium concept that eliminates strategies that are not credible, meaning that they would not be played by a rational player in any subgame of the original game.

In experimental economics, what is the purpose of using random assignment?

  1. To ensure that participants are evenly distributed across different treatment groups.

  2. To minimize the effects of confounding factors on the results of an experiment.

  3. To increase the sample size and statistical power of an experiment.

  4. To reduce the likelihood of bias in the results of an experiment.


Correct Option: A
Explanation:

Random assignment is used in experimental economics to ensure that participants are evenly distributed across different treatment groups, which helps to minimize the effects of confounding factors and reduce the likelihood of bias in the results.

Which of the following is a common method used in experimental economics to study individual decision-making under uncertainty?

  1. Laboratory experiments

  2. Field experiments

  3. Surveys

  4. Econometric analysis


Correct Option: A
Explanation:

Laboratory experiments are a common method used in experimental economics to study individual decision-making under uncertainty. In these experiments, participants are presented with hypothetical scenarios and asked to make choices under conditions of risk or uncertainty.

What is the main goal of experimental economics?

  1. To test and validate economic theories and models.

  2. To develop new economic theories and models.

  3. To provide policy recommendations to governments and organizations.

  4. To educate students about economic principles.


Correct Option: A
Explanation:

The main goal of experimental economics is to test and validate economic theories and models by conducting controlled experiments in which participants make economic decisions under specific conditions.
