Dictator game#Trust game

The confidence game is a social dilemma, which can be analyzed in the framework of game theory. It involves a two-person game with a trustor or trust donors (A) and a trustee or trustee (B). The settlor may entrust the fiduciary with a task. First, decide the settlor, if he gives the trustee trust or not. If he chooses the first option can now turn to the trustee to decide whether he abused the trust placed in him a) or b ) rewarded. For these options, three alternatives, none of which, for each of the two parties different payouts result found. The trust game can be a so-called sequential game ( optimal display here is the game tree ) or as a simultaneous game ( optimal representation is the matrix form ) depict. Here is a payoff matrix is chosen to illustrate:

A rational trustee will now choose to abuse the trust placed in him, because he gets so the highest payout for themselves. Because a settlor suspects this he will give only no confidence. This means that both players get nothing. Can be solved this dilemma on the one hand by the fact that the settlor has experience with the trustee and thus the behavior of the trustee is predictable. On the other hand, the settlor also exercise control over the trustee and impose sanctions for abuse of trust. When instrument of control the desired behavior of the trustee from the trustor is "forced" to a certain extent. Therefore, this solution corresponds to the exercise of power by the trustor on the trustee ( with the sanction as appropriate means of power ). If the problem can be overcome, however, by the fact that ( credible ) experiences are present, such as a favorable reputation of the trustee regarding his loyalty or his character, then the trust game can actually be solved by trust. The good reputation would be the basis of trust, the settlor can support his expectation in this case.
