In the standard IG, two players receive an endowment and are assigned either the role of a trustor (investor) or a trustee. The trustor may choose either to trust,that is, pass any portion of the endowment to the trustee while keeping the rest, or to distrust by sharing no money(trust stage). If the trustor shares, the money is multiplied(usually tripled) by the experimenter and passed on to the trustee. The trustee can now reciprocate, that is, pass anyportion of the money back to the trustor while keeping the rest, or betray by keeping the entire amount (reciprocity stage). At the end of the game, the trustor is informed about the trustee’s decision and the overall gains (feedback stage).
