Individual and group behaviour in the traveler's dilemma: An experimental study

We provide an experimental test of the traveler's dilemma using individual and group data. Our investigation aims to assess whether individual decisions differ significantly from group decisions. Experimental findings reported in this paper show that: (1) groups are always more rational – i.e. their claims are closer to the Nash equilibrium; (2) the size of the penalty/reward influences convergence to the equilibrium both when decisions are taken individually or in groups; and (3) groups are more sensitive to the size of the penalty/reward.
