Trust, reciprocity, and cheap talk Standard microeconomics implies a particular view of trust between agents: it can only exist under incentive mechanisms. In the experiment reported in this paper, the Dynamic Investment Game, in which such standard incentive mechanisms are not present but in which trust can lead to mutual gains, we find that certain individuals exhibit trust and thereby induce others to reciprocate. A static game theoretic model with incomplete information which contains a concept of fairness equilibrium more accurately describes behaviour in the experiment than the standard model. We further study behavior in this game with a second series of experiments in which cheap talk is permitted. Our results confirm the existence...
