Q1. Suppose two players, First and Second, take part in a sequential-move game. First moves first,...
Consider a sequential move game with two players. If the player who moves first has two or more strategies that offer him the same payoff, which one will he choose?
4. Consider the following game that is played T times. First, players move simultaneously and independently. Then each player is informed about the actions taken by the other player in the first play and, given this, they play it again, and so on. The payoff for the whole game is the sum of the payoffs a player obtains in the T plays of the game A 3,1 4,0 0,1 В 1,5 2,2 0,1 C 1,1 0,2 1,2 (a) (10%) Suppose...

Consider two players (Rose as player 1 and Kalum as player 2) in which each player has 2 possible actions (Up or Down for Rose; Left or Right for Kalum. This can be represented by a 2x2 game with 8 different numbers (the payoffs). Write out three different games such that: (a) There are zero pure-strategy Nash equilibria. (b) There is exactly one pure-strategy equilibrium. (c) There are two pure-strategy Nash equilibria.
Consider two players (Rose as player...
3. (15 points) Consider a sequential game with two players with three-moves, in which player 1 moves twice: Player 1 chooses Enter or Erit, and if she chooses Exit the game ends with payoffs of 2 to player 2 and 0 to player 1. • Player 2 observes player l's choice and will have a choice between Fight or Help if player 1 chose Enter. Choosing Help ends the game with payoffs of 1 to both players. • Finally, player...
(a) There are two players in this game - A and B. A moves first and can go either left L or right R. B does not see what A did, and can go either up U or down D. If B went D, A moves again, and can choose 1, c, or r. If B went U then A can move again only if he started with going L in the beginning. In this case A can choose either...
Consider the following game: there are two players, an incumbent (denoted I) and a potential entrant (denoted E) to the market. The entrant has two actions: it can either enter the market in which the incumbent operates, or not enter. The incumbent has two actions: it can either fight the entrant, or accommodate. The payoffs are as follows: if E enters and I fights, E gets -1 and I gets 2. If E does not enter, I gets 10 for...
Consider a variant of the Nim game called "Stones". Suppose that initially there is a single pile of 5 stones and two players, I and II. Each player takes turns picking up either 1 or 2 stones from the pile. Player I moves first, then Player II, then Player I, etc. until all stones have been picked up 3. Assuming that the loser is the player who picks up the last stone, write the game of Stones out in extensive...
Problem 1. (20 points) Consider a game with two players, Alice and Bob. Alice can choose A or B. The game ends if she chooses A while it continues to Bob if she chooses B. Bob then can choose C or D. If he chooses C the game ends, and if he chooses D the game continues to Alice. Finally, Alice can choose E or F and the game ends after each of these choices. a. Present this game as...
Brothers: Consider the following game that proceeds in two stages: In the first stage one brother (player 2) has two $10 bills and can choose one of two options: he can give his younger brother (player 1) $20 or give him one of the $10 bills (giving nothing is inconceivable given the way they were raised). This money will then be used to buy snacks at the show they will see, and each $1 of snacks purchased yields one unit...
5. Consider the payoff matrix below, which shows two players each with three strategies. Player 2 A2 B2 C2 A1 20, 22 24, 20 25, 24 B1 23,26 21,24 22, 23 C1 19, 25 23,17 26,26 Player1 STUDENT NUMBER: SECTION: Page 11 of 12 pages Find all Nash equilibria in pure strategies for this simultaneous choice, one play game. Explain your reasoning. a) b) Draw the game in extended form and solve assuming sequential choice, with player 2 choosing first.
