Quick Summary

The Shapley value is a concept in game theory that determines a fair distribution of payoffs among players in a cooperative game. Developed by mathematician Lloyd Shapley, it addresses situations where players contribute unequally to a group's success. The Shapley value calculates each player's average marginal contribution, ensuring that those who contribute more receive a proportionally larger share of the rewards. This method is used to ensure equitable outcomes in various scenarios, from business partnerships to resource allocation.12
