Document Summary

Tragedy of commons - farmer wants to put as many sheep as he can on common raising ground then the commons can support, therefore the commons get over used. Can lead to deterioration of the grounds with too many sheep (invdual bene t) which negatively effects the whole group. Each person gets 10$ and everyone can contribute any number of dollars to the middle. The money in the middle gets summed up then the experimenter doubles it, then everyone gets an even share regardless of what the contributed - cooperation. Conditional cooperation- only cooperates if others do, so if one person doesn"t it kind of fucks up everything. One person not contributing and gaining money - would u pay 1$ for them to lose. 4 yah fuck him i want to punish him. Someone who contributed relevant to the rest of the group levels of punishment is a lot higher for people who contribute a lot less,
