The Shapley-Shubik Power Index Idea: The more sequential coalitions for which player P i is pivotal, the more power s/he wields. Let SS i = number of sequential coalitions where P i is pivotal. The Shapley-Shubik power index of player P i is the fraction ˙ i = SS i total number of sequential coalitions. and the Shapley-Shubik power ...The Shapley–Shubik power goes to zero as \(N \rightarrow \infty \) as well, in fact, even faster than the Penrose–Banzhaf power (see Proposition 3). It may be somewhat surprising that the Shapley–Shubik success rate does \(not \) go to \(\frac{1}{2}\) for large N, but rather stays at about \(\frac{3}{4}\) independent of the size of V.

To calculate the index of a voter we first list all of the permutations of voters. If there are 3 voters there will be 3! = 6 permutations, with 4 voters there will be 4! = 24 permutations, and so forth. The Shapley–Shubik power index was formulated by Lloyd Shapley and Martin Shubik in 1954 to measure the powers of players in a voting game. The index often reveals surprising power distribution that is not obvious on the surface. The constituents of a voting system, such as legislative bodies, executives, shareholders, individual legislators, and so forth, …Born: 1923, Cambridge, MA, USA. Died: 2016, Tucson, AZ, USA.

Shapley-Shubik Power Index (SSI) has been applied in the notion of power for yes-no voting systems.
