Shapley-shubik power distribution.
Chapter 10, “Power and the Shapley Value,” by Peters, deals with a family of power indices, including Shapley-Shubik, Shapley-Owen, Banzhaf, and Banzhaf-Coleman measures of pivotal players in a political party or parliament, who can turn a coalition from a loser to the winner by joining it.
The Shapley-Shubik power index was introduced in 1954 by economists Lloyd Shapley and Martin Shubik, and provides a different approach for calculating power.
