When you write "If the others continue to cooperate, their bid is lower and they get nothing" you imply an iterated game. It seems clear from Hamermesh's account that players were only allowed to submit one bid.

Sorry for the poor phrasing. I didn't read it as an iterated game at all. That statement should instead read, "If the others nevertheless cooperate, ... "

Should I update it? How do you do the strikeout/line-through thing.
