Nov 25, 2019 · The Shapley-Shubik power index is a game-theoretic approach to this non-linear transformation from vote share to the degree of power. To formally define this index, we introduce some notations. Suppose that there are n shareholders on company j and \(q \in (0.5,1]\) of total shares are necessary to pass a bill in a shareholders meeting.

The value of an uncertain outcome (a ‘gamble’, ‘lottery’, etc.) to a participant is an evaluation, in the participant’s utility scale, of the prospective outcomes: It is an a priori measure of what he expects to obtain (this is the subject of ‘utility theory’). In a similar way, one is interested in evaluating a game; that is ...Program ssdirect. This page enables you to calculate Shapley-Shubik indices exactly using the program ssdirect which employs the fundamental definition directly.

Reference [10] shows that computing the Shapley-Shubik index in weighted majority games is #P-complete. Similar results [25,27] show that calculating both the Banzhaf and Shapley-Shubik indices in weighted voting games is NP-complete. The problem of power-index comparison is studied in [12], and is shown to also be hard in general.

We provide a new axiomatization of the Shapley-Shubik and the Banzhaf power indices in the domain of simple superadditive games by means of transparent axioms.

The value is required to satisfy the following four axioms.

Moreover, stochastic games were first proposed by Shapley as early as 1953. Potential games which are extensively used by researchers these days were proposed by Shapley and Dov Monderer in 1996. His joint work Shapley-Shubik index was given quite a few years later by Dubey [3]. Nowadays, the Shapley-Shubik index is one of the most established power indices for committees drawing binary decisions. However, not all decisions are binary.
