Professor Parallax chooses two students in his economics class, Jasmine and Cassandra,
to participate in the ultimatum game. He chooses Jasmine to be the allocator and
Cassandra to be the recipient. He gives Jasmine $50 and as the allocator, she gets to
decide how to split the money with Cassandra. If Cassandra decides to accept the

decides to reject her allocation, neither student gets to keep the money. How much will
each student end up with if each student acts as if fairness is important? How much will
each student end up with if only Cassandra acts as if fairness is important? How much
will each student end up with if neither student cares about fairness?

Figure 14-9
Refer to Figure 14-9. Uniguest, Inc. is a company that provides PCs with internet
access and touch-sensitive screens to hotels. Suppose the Hard Rock Hotel and Casino
in Las Vegas informs Uniguest that it is considering installing these systems in its hotel
rooms. The Hard Rock expects to be able to charge higher prices for these rooms if it
installs Uniguest's systems in its rooms. The two companies begin bargaining over what

reject this offer? Why?
b. Suppose the Hard Rock offers Uniguest $800 per system. Will Uniguest accept or
reject this offer? Why?
