The Shapley-Shubik model for voting systems assumes that on any issue to be voted upon there is a spectrum of opinion, and that various issues under consideration have different spectra of opinion. The Shapley-Shubik model is based on voting permutations. Definition: Voting Permutation tends Shapley-Shubik’s and Demange-Gale’s models as they are particular instances where the games , are strictly competitive. In addition, as proved by Gale and Sotomayor [6] for the marriage problem, we prove that our algorithm outputs the highest element, with respect to the proposer side, of the lattice.To perform the Shapley–Shubik power index one simply provides the number of members of each party and the minimum amount of votes needed to pass a vote. For instance, for the 2003 elections, the reader only needs to define an object containing the seats distribution, and another object with the labels of the parties for the analyzed period. Therefore, the …This method was originally proposed by Mann and Shapley (1962, after a suggestion of Cantor). The program ssgenf is an adaptation of that published by Lambert (1988).
