Zero-sum, part 1

Finishing up writing my final exams.  I am particularly proud of the last problem on my Game Theory final:

Update 1

Sadly, my department head nixed this problem as is; or rather, he wouldn’t let me do it without having students sign a “Human Participant” waiver prior to taking the test… which, in hindsight, would have been doubly awesome:

“Here. Sign this form legally absolving me from any psychological damage this exam might inflict upon you.”

In the end, I changed it to an extra-credit variant, with five points for everyone, unless greedy people decided they wanted more.

Update 2

The results: 22 people accepted, and 1 wanted more.  I had a very ethical class this semester.
