Abstract

For the classical power indices there is a disproportion between power and relative weights, in general. We introduce two new indices, based on weighted representations, which are proportional to suitable relative weights and which also share several important properties of the classical power indices. Imposing further restrictions on the set of representations may lead to a whole family of such indices.

Keywords: voting power, power indices, proportionality, weighted majority games, representations

JEL Classification: C71, D71
