In the ultimatum game, two strangers are given $50 and must decide how to split the money between them. One player, called the proposer, makes the initial decision on how to split the money.

If the responder rejects the offer, neither player receives any money.
a. Suppose the proposer and responder act in a rationally self-interested manner. What split would the proposer offer? How would the responder reply?
