What is non transferable utility game ntu?

A non-transferable utility (NTU) game is a type of cooperative game where the benefits or payoffs resulting from cooperation among players cannot be freely transferred between them. In NTU games, players must achieve outcomes that are beneficial to all parties involved without the ability to redistribute their utility or resources. This contrasts with transferable utility (TU) games, where players can negotiate and share payoffs. NTU games often involve complex negotiations and coalition formations, as the utility of each player depends on the specific agreements made with others.
