Shapley-Shubik Power Definition (Pivotal Count) A player’spivotal countis the number of sequential coalitions in which he is the pivotal player. In the previous example, the pivotal counts are 4, 1, 1. Definition (Shapley-Shubik Power Index) TheShapley-Shubik power index (SSPI)for a player is that player’s pivotal count divided by N!. The first definition, the delegate, elector or representative weighted voting definition is common at highest levels of governance and decision-making. This type of feature of an electoral system is used in many companies' shareholder meetings.

A simple game is an abstraction of the constitutional political machinery for voting. In 1954, Shapley and Shubik [ 2] proposed the specialization of the Shapley value [ 3] to ... Reference [10] shows that computing the Shapley-Shubik index in weighted majority games is #P-complete. Similar results [25,27] show that calculating both the Banzhaf and Shapley-Shubik indices in weighted voting games is NP-complete. The problem of power-index comparison is studied in [12], and is shown to also be hard in general.

and. 1002 = 10,000. Page 26. Calculating Shapley-Shubik Power Indices. For any weighted voting system with N ...The Shapley–Shubik power index considers all possible permutations (orderings) of all players. Each player is incorporated into the coalition formed by the players preceding it in the permutation. In each permutation, there is a critical player, i. e., a player who changes a losing coalition into a winning one.
