Game theory is a useful tool for analyzing
Situations in which multiple parties make decisions that do not affect each other.
Situations in which multiple parties make decisions with the potential to affect each other.
Situations in which multiple parties make decisions.
Situations in which one party makes a decision with the potential to affect other parties.
Any situation in which a decision must be made.
Nash equilibrium refers to the optimal outcome of a game where there is no incentive for the players to deviate from their initial strategy. An individual (or player) can receive no incremental benefit from changing actions, assuming other players remain constant in their strategies. Given this premise, can there be a no Nash equilibrium?
You have just played rock, paper, scissors with your friend. You chose scissors and he chose paper, so you won. Is this a Nash equilibrium? Explain why or why not.

- Which of the following problems makes it difficult to interpret human experiments using cooperation games based on economic game theory? If you compare humans from different cultures, you get different results which defeats the purpose. These games do not test human behavior under conditions that are ecologically realistic. Economic game theory assumes that humans are selfish, but actually we are cooperative. Humans choose to cooperate because they are related.arrow_forwardGame theory is designed to study situations in which each agent's decisions are: A)interdependent. B)independent. C)constrained.

- From your own understanding on the concept of “Game Theory”, what can you conclude about the relationship between rules of the game and the outcome that results?arrow_forwardTrue or false? If a game has a Nash equilibrium, that equilibrium will be the equilibrium that we expect to observe in the real world. False. People don’t always act in the way that a Nash equilibrium requires. People don’t always make the necessary calculations and they take into account the outcome of others. False. A Nash equilibrium is based on very strict assumptions that rarely hold in the real world. No real-world situation leads to a Nash equilibrium. True. As long as people are rational and have their own self-interest at heart, real-life games will result in the Nash equilibrium. True. Nash’s theory of equilibrium outcomes was derived from real-world interactions. The theory holds true for almost all real-world scenarios.arrow_forwardEconomics Consider the ultimatum and dictator games. a) Briefly explain the general experimental findings about how individuals play these games. How do they compare with the game theoretic predictions? b) How do social preferences explain behavior in these experiments? c) Real world experiences have an impact on experimental behavior.

Can you think of a way to to this? e) Suppose that individuals play first a dictator game and then an ultimatum game with the roles reversed, i.e. the sender in the dictator game is the receiver in the ultimatum game. Given what you know about individuals' behavior, how do think that players will play? Explain. youarrow_forward
- Is the solution to the prisoner’s dilemma game a Nash equilibrium? Why? The solution to the prisoner’s dilemma game is a Nash equilibrium because no player can improve his or her payoff by changing strategy unilaterally. The solution to the prisoner’s dilemma game is not a Nash equilibrium because players do not end up in the best combination for both. The solution to the prisoner’s dilemma game is not a Nash equilibrium because both players can improve their payoffs by cooperating. The solution to the prisoner’s dilemma game is a Nash equilibrium because it is a noncooperative game in which both players have to expect that the other is purely selfish.arrow_forwardConsider a game between 2 payers (Ann and Bill) where each chooses between 3 actions (Up, Middle and Down). 1) Create a payoff matrix that reflects this. 2) Fill in payoff numbers that makes this game a Prisoner's Dilemma. 3) Explain why your game is a Prisoner's Dilemma.arrow_forwardA Nash Equilibrium is the equilibrium of a game in which; Both players get the largest payoff amount Both players get the best payoff independent of what the other players choices are Both player, with the knowledge of what the other players possible moves are, do not have incentive to deviate from their strategy There is incomplete information of the game and each player makes the move that is best for them and their payoff outcomearrow_forward
