Voting: a game theory look

[Dan.]

Borodog's thread inspired me, but I decided to create a new thread to discuss it.

Basically, it's possible that no one vote at all. However, if no one votes, a single person has incentive to "cheat" the no-one-vote agreement, since his or her vote would be the only one counted, so whatever he or she says goes. Now, if one person cheats, another then also has incentive to cheat, and the result is a landslide where a whole slew of people go out and vote, since they all are given incentive to vote. It's a very simple game theory problem relating to cartel agreements, quite common in microeconomics.
