The trust game is one of the foundational games in experimental economics and behavioral economics.[1]

In the basic two-player game, there are two players, each of whom is endowed with an equal initial endowment.[2]

One of the two players is a first mover-- sometimes referred to as the Trustor-- who chooses between Invest and Not Invest. Not investing guarantees the first mover his initial endowment as a sure outcome. Investing transfer the entire invested amount by the first mover to the second mover, multiplied by 3. That invested amount is subtracted from the first mover's endowment.[3]

If the first mover invests, the second mover-- referred to as a Trustee-- receives the entire investment of the fist mover, multiplied by 3. He can choose how much to transfer back to the first mover.[4]

If the second mover transfer any amount over 1/3 of the investment to the first mover, then the first mover is as well off as he would have been had he not invested. However, the second mover has a strategic dominance in the sub-game of transferring back nothing at all.[5][6]

By backward induction, the first mover can expect to receive nothing, and therefore he is better off not investing.[7]

The trust game is sometimes erroneously referred to as a variant of the dictator game.[8]
