Exam 7: Explaining Tastes: The Importance of Altruism and

The hawks and doves example illustrate in the textbook illustrate how the usefulness of a certain mode of behavior depends on:

Given the following: if Shirley believes Betsy will behave in a self-interested way, Shirley will                                 $\text { Betsy }$ defect Shirley cooperate defect cooperate 1 for each 0 for Betsy 3 for Betsy 3 for Betsy 0 for Betsy 2 for each

If the teacher allows students to choose partners for a 1/3 letter grade penalty, what will happen to the student body population.Draw another payoff graph and show the proportion of socialites and individualists on the graph.You cannot use a numerical percentage because the letter grades are not numerically specified.Simply label the horizontal axis with an X at the left side and a Y on the right side and a Z where the proportion of socialites will be fixed.The percentage population then becomes XZ/XY.

What is the strategy we would expect from X and Y in the following prisoner's dilemma?                                     $\text { Prisoner Y }$ confess Prisoner X remain silent confess remain silent 10 years each 0 years for 30 years for 0 years for 30 years for 2 years for each

If you care not only about your own income level but also about your relatives' income level, with increasing concern for them as they get poorer, then your indifference curves (defined over your income level and that of your relatives)

Say Anna's utility function was given by UA = MAMM, where MA is Anna's wealth and MM is Marie's wealth. Initially, Anna has 160 units of wealth and Marie has 40. In order to maximize her utility Anna should:

Consider a population with the following givens: 1) 75% cooperators and 25% defectors, 2) a 8 unit payoff goes to cooperators who interact with another cooperator, 3) a zero unit payoff goes to a cooperator who interacts with a defector, 4) the cost of knowing which is which is 2 If the population balance falls below 75%

The self-interest model predicts that the outcome of the "ultimatum bargaining game" in which the allocator starts with $20 is that

When Anna maximizes her utility her utility level is equal to:

In a society consisting of 75% cooperators and 25% defectors, with an 8-unit payoff to a cooperator who interacts with another cooperator and a 0-unit payoff to the cooperator who interacts with a defector, if the cost of scrutiny is 2, the cooperator

In the prisoner's dilemma exercise, the strategy that is assumed to result is which of the following?

In this chapter, virtue can lead to material gain and therefore is an inevitable part of the social order.Evaluate this view of virtue or moral behavior.Is material gain a sufficient motive for morality? Is moral behavior based on more than the possibility for personal gain?
