Harsanyi Solution

The Harsanyi solution, developed by John Harsanyi, addresses how individuals can reach fair agreements in situations where they must share resources or make decisions together, especially when they have different preferences or incomplete information. It relies on the idea of assuming everyone has equal knowledge and can understand each other's interests. By considering a potential agreement that maximizes overall benefits, the Harsanyi solution seeks to balance fairness and efficiency, helping all parties reach a consensus that accommodates their varying needs while ensuring that no one is unfairly disadvantaged.
