Two people, Baker and Cutler, play a game in which they choose and divide a prize. Baker decides how large the total prize should be; she can choose either $10 or $100. Cutler chooses how to divide the prize chosen by Baker; Cutler can choose either an equal division or a split where he gets 90% and Baker gets 10%. Write down a payoff table of the game and find equilibria for the following situations and answer the final question about whether this is a Prisoner's Dilemma.

(a) When the moves are simultaneous

(b) When Baker moves first

(c) When Cutler moves first

(d) Is this game a Prisoner's Dilemma? Why or Why not?

Solutions

Expert Solution

a) the payoff table:

Cutler
Equal unequal
Baker 10 5. 5 1, 9
100 50, 50 10, 90

b) When Baker moves first:

If Baker were to move first, she would know that Cutler would choose unequal for sure (higher payoff for Cutler). So she chooses 100. Because 100 would give her a payoff of 10 against 1 from selection of 10. So the equilibrium is (100, unequal)

c) When Cutler moves first:

If Cutler were to move first, he would know that Baker would select 100 (higher payoff than 10). So he would choose unequal so that she would get 90 (comapred to 50 if she chose equal.) So the equilibrium is (100, unequal)

d) This game is not like prisoner's dilemma. reason: In prisoner's dilemma, the players have dominated strategies, but it brings a lower outcome than dominated strategy. So the equilibrium is the second best outcome. In this game, Cutler has a dominatted strategy, and he plays it.

The Ultimatum Game: A and B are two individuals who are to divide $100. A (chosen randomly by a coin toss) makes an offer to B. There is a minimum offer of $10. Assume, for simplicity, that offers must be evenly divisible by 10 (i.e., A can offer $10, or $20, or $30 etc.) B can either accept or reject the offer. If B accepts, they split the $100 as per the amount offered. For example, if A offers $20,...

Consider the following game, which might model the “Split-or-Steal” game show. Two players simultaneously choose whether to split or steal. If they each choose to split, they each get $50. If one chooses steal and the other chooses split, then the stealer gets $100 and the splitter gets $0. If both choose steal, they each get $0. (a) Assume the players care both about their own monetary earnings and the amount of inequality between their earnings: for a pair of...

After player 2 makes her counteroffer –if she does– player 1 can accept or reject the counteroffer. As before, if there is no agreement after the two rounds of offers, neither player gets anything. If there is an agreement in either round then each player gets the amount agreed to.Represent the...

Game Description: The popular rock-paper-scissors game is usually played between two people in which each player simultaneously chooses either a rock or a paper or scissors (usually with an outstretched hand). The rule of the game is simple: rock crushes scissors, scissors cut paper, and paper wraps rock. If both the players choose the same object, then it ends in a tie. Problem Description: You have to play the rock-paper-scissors game against the computer for 100 times. You receive the...

Two people are playing an exciting game in which they take turns removing marbles from a bag. At the beginning of the game, this bag contains some red marbles and some blue marbles. The bag is transparent so at any time during the game, the players know exactly how many red and how many blue marbles are in the bag. The players alternate taking turns. On a player’s turn, he or she must remove some marbles from the bag. The...
