Measures of Powerlessness in Simple Games

Author

  • Thomas Quint

Abstract

Consider a simple game with n players. Let ψ i be the Shapley–Shubik power index for player i. Then 1-ψ i measures his powerlessness. We break down this powerlessness into two components – a `quixote index' Q i (which measures how much of a `quixote' i is), and a `follower index' F i (which measures how much of a `follower' he is). Formulae, properties, and axiomatizations for Q and F are given. Examples are also supplied. Copyright Kluwer Academic Publishers 2001
