The Shapley value not only has desirable properties, it is also the only payment rule satisfying some subset of these properties. For example, it is the only payment rule satisfying the four properties of Efficiency, Symmetry, Linearity and Null player. See for more characterizations. Visa mer The Shapley value is a solution concept in cooperative game theory. It was named in honor of Lloyd Shapley, who introduced it in 1951 and won the Nobel Memorial Prize in Economic Sciences for it in 2012. To each Visa mer Formally, a coalitional game is defined as: There is a set N (of n players) and a function $${\displaystyle v}$$ that maps subsets of players to the real numbers: The function Visa mer The Shapley value has many desirable properties.
