We analyze and evaluate the different decision rules describing the Council of Ministers of the EU starting from 1958 up to date. Most of the existing studies use the Banzhaf index (for binary voting) or the Shapley-Shubik index (for distributive politics). We argue in favor of the nucleolus as...

This paper introduces a new storable vote mechanism (storable votes, pay-as-you-win-mechanism, SV-PAYW) where a fixed number of votes can be cast among different alternatives, and the votes spent (and redistributed) on each election depend only on the number cast for the wining alternative. The...

This paper deals with the problem of calculating the Shapley-Shubik power index in weighted majority games. We propose an efficient Monte Carlo algorithm based on an implicit hierarchical structure of permutations of players. Our algorithm outputs a vector of power indices preserving the...
