In this study, you will be in a randomly formed group
of 3 participants. Each participant in
the group is given 100 points. The group
has the opportunity to undertake a joint project. Each participant in
the group decides how much she or he is going to contribute to
the project. Contribution could be any integer from 0
to 100 points.
The earnings from the project are calculated as follows: The
contributions of all 3 participants are
added up, the total contribution
is multiplied by a factor of 2, and the
resulting amount is the total earnings from the project, which is
evenly split among all 3
participants. Your payoff equals your earnings from the project, plus
the amount you did not contribute.
