GWD-7-Q6 to GWD-7-Q9:
For many years, theoretical
economists characterized humans
as rational beings relentlessly bent
Line on maximizing purely selfish reward.
(5) Results of an experimental economics
study appear to contradict this view,
however. In the “Ultimatum Game,”
two subjects, who cannot exchange
information, are placed in separate
(10) rooms. One is randomly chosen to
propose how a sum of money, known
to both, should be shared between
them; only one offer, which must
be accepted or rejected without
(15) negotiation, is allowed.
If, in fact, people are selfish and
rational, then the proposer should offer
the smallest possible share, while the
responder should accept any offer,
(20) no matter how small: after all, even
one dollar is better than nothing. In
numerous trials, however, two-thirds
of the offers made were between
40 and 50 percent; only 4 percent
(25) were less than 20 percent. Among
responders, more than half who were
offered less than 20 percent rejected
the offer. Behavior in the game did not
appreciably depend on the players’
(30) sex, age, or education. Nor did the
amount of money involved play a
significant role: for instance, in trials
of the game that were conducted in
Indonesia, the sum to be shared was
(35) as much as three times the subjects’
average monthly income, and still
responders refused offers that they
deemed too small.

GWD-7-Q9:
All of the following are expressly mentioned in the passage as factors that did not significantly affect players’ behavior EXCEPT the
- players’ level of schooling
- amount of money to be shared
- ages of the players
- players’ professions
- genders of the players
