The purpose of this paper is to present a structural specification of the Shapley- Shubik and Banzhaf power indices in a weighted voting rule. We compare them in term of the cardinality of the sets of power vectors (PV). This is done in different situations where the quota or the number of seats are fixed or not.
Keywords: Shapley-Shubik; Banzhaf; power index; power vectors. (search for similar items in EconPapers)
