Punishment in Experimental Games, Pablo Brañas-Garza
"In daily life, subjects sanction other individuals if they behave in an unacceptable way. This means that punishers pay a cost to punish other subjects if they behave improperly (or violate the right social rule at hand). Punishment has been extensively studied in strategic environments, i.e games.
In my talk I will provide three examples: First, I will show how subjects change their behaviour in a repeated experiment under threat from an exogenous mechanism (robot) following a tit-for-tat rule. That is, subjects are punished if they deviate from the cooperative social rule.
Secondly, I discuss the 'Ultimatum' bargaining game where second movers have the option to punish first movers if they do not propose a 'fair' allocation. While the sequential game is more 'realistic' (in the sense that subjects decide on strategies once they already know their partners choices) the simultaneous game provides us with more information. I will provide experimental evidence of both experimental games.
Finally, I will focus on an experiment where subjects play a one-shot 'public good' game with endogenous punishment, that is, subjects may punish each other if they disapprove of what other subjects have done. I will show that time preferences make a critical difference in punishment for both co-operators and defectors."
