A sequential game with two-players 1 and 2, where player 1 has the first move advantage. Each player has two strategies, A and B. If both players choose A, each gets a payoff of 2. Both choose B, each gets a payoff of 3. For player 1 choose A and player 2 choose B, player 1 gets 4, and player 2 gets 1. If player 1 chooses B and player 2 choose A, player 1 gets a payoff of 1, and player 2 gets 4. How many, if there is any, subgame perfect equilibrium are there?

This question is about the sequential moves Stag Hunt game. There are two players. Player 1 moves first, player 2 observes player 1’s move, and then player 2 moves. Players get 10 jollies each if they both choose Stag; 5 jollies if they choose Hare; and 0 jollies if they choose Stag but the other player does not. What is the set of (pure) strategies for player 1? What is the set of (pure) strategies for player 2? Explain why...

This is a sequential game with two players A and B. In this game a dime is put on the table. A can take it or pass. If A takes a dime, the game ends; if A passes, then B can take 2 dimes or pass; if B takes 2 dimes, the game ends; if B passes, then A can take 3 dimes or pass; and so on until a choice of a dollar. This process is shown in the...

Coin taking game This game is played between 2 players, player 1 and player 2. There are two piles of coins. The values of a coin can be any integer. Both players know the values of all coins in both piles. Player 1 makes the first move, and play alternates between the players. A move consists of taking a coin from the top of either of the piles (either player can take from either pile). The game ends when both...

Consider the following game that has two players. Player A has three actions, and player B has three actions. Player A can either play Top, Middle or Bottom, whereas player B can play Left, Middle or Right. The payoffs are shown in the following matrix. Notice that a payoff to player A has been omitted (denoted by x). Player B    Left Middle Right Top (-1,1) (0,3) (1,10) Middle (2,0) (-2,-2) (-1,-1) Bottom (x,-1) (1,2) (3,2) (player A) Both players...

Consider a game with two players, each of whom has two types. The types of player 1 are T1 = (a,b). The types of player 2 are T2 = (c,d). Suppose the beliefs of the types are p1(c/a) = p2(a/c) = 0.25 and p1(c/b) = p2(a/d) = 0.75. Is there a common prior? If yes, construct one; if no, prove why not.

This game is meant for two or more players. In the game, each player starts out with 50 points, as each player takes a turn rolling the dice; the amount generated by the dice is subtracted from the player’s points. The first player with exactly one point remaining wins. If a player’s remaining points minus the amount generated by the dice results in a value less than one, then the amount should be added to the player’s points. (As an...

Two players play a rock-paper-scissors game. The losing player will give $1 to the winning player. If it is a draw, no payment is made. The payoff to a player is the amount of money (s)he gets. Represent the situation in a matrix form. Find all the Nash equilibria.

The game of Pig is a simple two-player dice game in which the first player to reach 100 or more points wins. How to play: Players take turns rolling one six-sided dice and following these rules: If the player rolls 2 through 6, then he/she can either a. “Roll Again” or b. “Hold” At this point, the sum of all rolls is added to the player’s score, and it becomes the other player’s turn. If the player rolls 1 before...
