Which of the following best defines a Nash Equilibrium? A) A situation where each player maximizes their own payoff without regard to the strategies of others. B) A situation where no player can improve their payoff by unilaterally changing their strategy. C) A situation where players cooperate to achieve the highest collective payoff. D) A situation where each players strategy maximizes the opponents payoff.
Consider the game shown below. In this game, players 1 and 2 must move at the same time without knowledge of the other player’s move. Player 1’s choices are shown in the row headings (A, B, C, D), Player 2’s choices are shown in the column headings (E, F, G). The first payoff is for the row player (Player1) and the second payoff is for the column player (Player 2).

Three married couples in the state of Maryland—Bob and Carol, Ted and Alice, and Ross and Mike (remember, same-sex marriage is legal in the state of Maryland)—are thinking about renting a boat to go sailing on the Chesapeake Bay. The cost of a boat rental is $600. Each of the three couples puts some amount of money in an envelope. Thus, each player in this game is a couple. If the total amount collected is at least $600, then the boat is rented. If the amount collected is more than $600, then the money left over after renting the boat is spent on wine. If the total amount collected is less than $600, then they do not rent the boat, and the money is spent on a dinner. Assume the benefit to a couple from the boat trip is 400, the benefit from each dollar spent on wine is 50 cents, the benefit from each dollar spent on dinner is 40 cents, and the personal cost of the contribution to a couple equals the amount of contribution. For example, if the boat is rented, $50 of wine is purchased…
Consider a one-time game involving a penalty kick in football/soccer. There are two players: kicker and goalkeeper. The kicker has two possible actions: kick left or right. The goalkeeper also has two possible actions: guess left or right. The kicker and goalkeeper move simultaneously. If the kicker and goalkeeper choose the same direction, the goalkeeper "wins" and the payoffs are (0,1). If the kicker and goalkeeper choose different directions, the kicker wins and the payoffs are (1,0). (a) Is there a pure strategy equilibrium in this game? Explain. (b) Derive and explain the mixed strategy equilibrium for this game.

Find all the Nash equilibrium. p. Suppose player 1 moves first or we are in a sequential game now. Draw the extensive form in the sequential version. c. What is the subgame perfect Nash Equilibrium (SPNE) in the sequential version? d. ) Explain why it is an SPNE.
Which of the following is the COLLUSIVE OUTPUT in the Game Theory Matrix below? * Firm B Payoff = Expected Profit ($m) High Price Low Price High Price $4m; $4m $-1m, $6m Firm A Low Price $6m; $-1m $1m, $1m Both firms choose High Price Both firms choose Low Price Firm A chooses Low Price; Firm B chooses High Price O Firm A chooses High Price; Firm B chooses Low Price
Imagine two Pizzerias are playing a static game where the firms have to choose their strategies simultaneously, selecting a strategy that maximizes its profit given what it believes the other firm will do. Their decision is how many pizzas to produce. They can choose between producing 100, 150 or 200 pizzas each. The profit for respective firm is showed in the payoff matrix below. a) What is the solution (if there is one) and also describe the characteristic features of this game. b) If this game was played repeatedly, could that potentially change the outcome of the game? In your answer, you are expected to motivate and describe how.
Consider the following simultaneous-move game that represents the payoffs from different advertising campaigns (low, medium, and high spending) for two political candidates that are running for a particular office. The values in the payoff matrix represent the share of the popular vote earned by each candidate is given below. The equilibrium in dominant strategies Candidate A-low Candidate A-medium Candidate A-high Ois (low. low). O is (medium, medium). O is (high, high). O is (medium, high) O does not exist. Candidate B-low Candidate B-medium Candidate B-high 50, 50 60,40 80, 20 40, 60 50, 50 65, 35 20, 80 35,65 50, 50
Consider the following representation of a hockey shootout. The shooter can shoot on their forehand, or deke to their backhand, and the goalie can anticipate either move. The number in each cell in the table below represents the percentage chance that the shooter scores for each pair of pure strategies. Anticipate Forehand Anticipate Backhand Shoot Forehand 20 40 Deke Backhand 40 10 In the mixed strategy Nash equilibrium of this game, what is the percentage chance that the player scores? (ie. An 80% chance should be recorded as 80)
Three politicians are voting on whether to allow themselves a salary increase of$3,500per a year. If they vote in favor of a raise, then they lose some public support, costing them each$1,500 per year. The salary increase passes if two or more politicians vote in favor of it. What is this game’s Nash equilibrium (or equilibria)? Explain. There is no need to draw a payoff matrix.
There are three players in this simultaneous move game. Player-3 chooses between game A and game B. Player-1 chooses between U, M and D. Player-2 chooses between L and R. The payoffs are given below: P-1 U M D A P-2 L R 5,5,0 1,4,0 6,4,5 2,5,3 3,1,2 3,3,1 Find all pure strategy N.E. of this game. P-1 U M D L 4,8,0 4,1,3 3,5,1 B P-2 R 2,1,0 3,3,3 0,3,0
Question 1 Consider the following game. Player 1 has 3 actions (Top, middle,Bottom) and player 2 has three actions (Left, Middle, Right). Each player chooses their action simultaneously. The game is played only once. The first element of the payoff vector is player 1’s payoff. Note that one of the payoffs to player 2 has been omitted (denoted by x). A) Suppose that the value of x is such that player 2 has a strictly dominant strategy. Find the solution to the game. What solution concept did you use to solve the game? B) Suppose that the value of x is such the player 2 does NOT have a strictly dominant strategy. Find the solution to the game. What solution concept did you use to solve the game?
