In Talking About the Berg Et Al

Essay

In talking about the Berg et al. trust game, Cox (2004), remarks "The source of the difficulty is that the single-game experimental designs used to generate the data in these experiments do not discriminate between actions motivated by trust or reciprocity and actions motivated by other-regarding preferences characterized by altruism or inequality aversion that is not conditional on the behaviour of others." Briefly discuss the triadic game design - using more than one game - that Cox (2004) uses in order to distinguish between trusting and other-regarding preferences. How does the approach of Ashraf et al. (2006) which uses a triple dictator game differ from that of Cox?
