In the trust game, one student plays the role of an investor who decides how much of his money to invest with the second student, who plays a financial planner. The financial planner receives the investment and the money grows. The financial planner then decides how much to return to the investor and keeps the remainder.
This game teaches students about the nature of trust and how it can be sustained over time. When the game is repeated, the students can explore issues concerning reciprocity.
