Preferred term

pivot player  

Definition

  • A pivot player is a player who, in the formation of a coalition, turns a losing coalition into a winning one. This term was introduced by Lloyd Stowell Shapley and Martin Shubik in an important article published in 1954 in which they particularized the Shapley value of a game (Shapley, 1953) in the context of voting games, thus creating the Shapley-Shubik power index.
