Imagine that you are playing the “ultimatum game” described in the box “Determinants of Cooperation” (page 423). The other player

(whom you cannot observe) is of your same economic and social group. The sum of money to be divided in the game is $1,000.

a. If you were the responder, what minimum payout would you accept? Explain why.

b. If you were the proposer, what division would you propose? Explain your reasoning.

c. How would your responses to parts a and b have differed if the sum of money to be divided was $10 instead of $1,000? Why?
