If Alice chooses action b, then Bob chooses action c or action d. If Bob chooses action c, then Alice receives a payoff of 10 and Bob receives a payoff of 5. If Bob chooses action d, then Alice receives a payoff of 0 and Bob receives a payoff of 6. Which of the following are correct statements about the game described in the previous paragraph? (Mark all that are correct.) Alice's backward induction payoff is 10. This is a prisoners' dilemma. This game has imperfect information. Alice's backward induction payoff is 0

Alice and Julia want to spend time together but have different preferences for their activities. They can choose between two options: going to a soccer game or watching a football game. Alice prefers football and Julia prefers the football game, but they both prefer being together over being apart. If they both choose to attend a soccer game then Julia receives a payoff of 2 and Alice a payoff of 1. If they both choose to attend a football game, then Julia receive a payoff of 1 and Alice a payoff of 2. If one chooses a football game and the other a soccer game then they both receive a payoff of O. The payout matrix below illustrates these payoffs. Which of the following statements are true: I. There is a dominant strategy II. A nash equilibrium exists where Alice attends a football game and Julia attends a soccer game III. A nash equilibrium exists where both friends attend a soccer game IV. Both attending a football game is a stable outcome. Alice Soccer Football Julia Soccer Football…
Eva and Ethan love attending sports events, especially when they go together. However, Eva prefers watching field hockey while Ethan would rather go to a cricket match. If they go together, the payoff is higher for the person who favors the sports event more (payoff = 3), and less for the other person (payoff = 2). If they attend the events alone, the payoff is smaller and the same for each (payoff = 1). Show the payoff matrix for this couple and deter- mine the Nash equilibria. How do the payoffs from the Nash equilibria compare?
Tinky Winky and Dipsy both choose to play an action, and the payoff from that choice is dependent on what the other player chooses. Both players choose their actions simultaneously and reveal their choice to each other at the same time.

Martin has a brother and can take a selfish action, which pays him $10 and his brother $0, or an altruistic action, which pays him $6 and his brother $6. The parents love their children equally and decide how to distribute $20 between them. The parents' payment is the minimum of their two children's payments. Assume that the game is simultaneous. Find the Nash equilibrium.
CLASSES OF GAMES First, Alice chooses either action al or action a2. If Alice chooses action al, then she receives a payoff of 2 and Bob receives a payoff of 8. If Alice chooses action a2, then Bob chooses either action b1 or action b2. If Bob chooses action b1, then Alice receives a payoff of 0 and Bob receives a payoff of 2. If Bob chooses action b2, then Alice receives a payoff of 4 and Bob receives a payoff of 4. Which of the following are correct statements about the game described in the previous paragraph? (Mark all that are correct.) This game has perfect information. The strategy profile (a2,b1) is a Nash equilibrium of this game. Bob's backward induction payoff is 8. The strategy profile (al,b1) is a Nash equilibrium of this game. The strategy profile (a1,b2) is a Nash equilibrium of this game. The strategy profile (a2,b2) is a Nash equilibrium of this game. This is a bargaining game. This is a promise game. This is a threat game. Alice's backward induction payoff is 2.
We consider a game between two players, Alice and Bob. Alice chooses a number x and Bob chooses a number y. Alice's payoff is given by the following function:50 x + 79 x y - 89 x 2 . (the last entry is "x squared".)Suppose that Bob plays y = 23. Calculate Alice's best response (round your answer to 2 decimals).
Two athletes of equal ability are competing for a prize of $12,000. Each is deciding whether to take a dangerous performance-enhancing drug. If one athlete takes the drug and the other does not, the one who takes the drug wins the prize. If both or neither take the drug, they tie and split the prize. Taking the drug imposes health risks that are equivalent to a loss of XX dollars. Complete the following payoff matrix describing the decisions the athletes face. Enter Player One's payoff on the left in each situation, Player Two's on the right. Player Two's Decision Take Drug Don't Take Drug Player One's Decision Take Drug , , Don't Take Drug , , True or False: The Nash equilibrium is taking the drug if X is greater than $6,000. True False Suppose there was a way to make the drug safer (that is, have lower XX). Which of the following statements are true about the effects of making the drug safer? Check all that…
Find the SPNE for the centipede game. Centipede game: Two players, 1 and 2, take turns choosing one of two actions each time, continue or stop. They both start with $1 in their respective piles, and each time i says continue, $1 is taken away from his pile, and $2 are added to the other player's pile. The game automatically stops when both players have $100 in their respective piles.

We consider a game between two players, Alice and Bob. Alice chooses a number x (between -infinity and +infinity), and Bob chooses a number y (between -infinity and +infinity). Alice's payoff is given by the following function: 35 x + 87 x y - 95 x squared. (the last entry is "x squared".) Bob's payoff is given by the following function: 30 y + 42 x y + 75 y squared. (the last entry is "y squared".) Calculate Alice's strategy in the (unique) Nash equilibrium of this game.
