Abstract:

Where behavior defies economic analysis, one explanation is that individuals consider more than the immediate payoff. We present evidence that noneconomic factors influence behavior. Attractiveness influences offers in the Ultimatum and Dictator Games. Facial resemblance, a cue of relatedness, increases trusting in a two-node trust game. Only by considering the range of possible influences will game-playing behavior be explained.

Notes

1. Relatedness refers not to the total proportion of genes shared, but to those shared by identical descent. In this case, r is the probability that the recipient shares a gene for altruism with the altruist.

2. The conclusion holds for any r > 0 with this particular game payoff structure.
