PSYC 472 Lecture Notes - Lecture 12: Extortion, Relational Aggression, Reciprocal Altruism
Document Summary
With: low contributors are punished, people contribute more. So if doesn"t affect you, seems like you don"t want to punish (seems more like revenge than cooperative norm enforcement) Caveat: in last round (where punishment doesn"t actually matter because there is no next round for the people who are punished) people punish others just as much (not a logical, calculated thing, more emotional/they are just irritated) Caveat: punishment reduces welfare: the size of a negative effect of a punishment on earnings is occasionally big, but most of the time does not change or can slightly negatively affect average payoff. Caveat: third party punishment diminishes when punishment is strictly anonymous, suggests punishment is motivated by reputational concerns. Caveat: counter punishment: if punishers can be punished in return, initial punishment decreases. Caveat: cross cultural variability: in some places people who contribute the most are punished (interpreted as showing off, a threat) Punishment as a way to sustain cooperation (yamagishi)
