A detailed analysis shows that in the repeated game some … subjects imitate reciprocity. Thus, reciprocity and repeated game incentives reinforce each other. Observed behaviour is robust …

Behavioural economists have come to recognize that reciprocity, the interaction of trust and trustworthiness, is a … power of trust as a determinant of those decisions, suggesting that altruism may explain much of what ‘looks like’ trust … protocols and framing.
