In this paper, the concept of decisional power is introduced and compared with other measures for power like those of Shapley-Shubik, Banzhaf and Dahl, and completely democratic structures are characterized.Abstract:
The concept of decisional power is introduced and compared with other measures for power like those of Shapley‐Shubik, Banzhaf and Dahl. The sum of the powers of all actors in a social network is maximal for certain structures of the network. These structures are called completely democratic. Completely democratic structures are characterized. In every network dictator sets are present. These can be found by use of Boole polynomials. Decisional power turns out to‐have both a causal aspect and a utility aspect and to allow for variations that express the power over other persons as well as the power in a certain state of the network.read more

A Priori Voting Power: What Is It All About?
Dan S. Felsenthal,Moshé Machover +1 more
TL;DR: The meaning of a priori voting power is explained and how it is measured, leading to two approaches to measuring it, which focus on a voter's potential influence over the outcome of decisions by a voting body.

Is politics power or policy oriented? A comparative analysis of dynamic access models in policy networks
TL;DR: In this article, the authors compare different models and investigate the resulting network structures and predicted outcomes of decisions and show that the policy driven models do fundamentally better than the power driven models.

Centrality and power revisited: actor success in group decision making
Mark S. Mizruchi,Blyden B. Potts +1 more
TL;DR: In this paper, the authors examine the effect of centrality on power in a communication network involving group voting on political issues and find that the link between centrality and power is highly contingent on the structure of the network.

The Impossibility of a Preference-Based Power Index
Matthew Braham,Manfred J. Holler +1 more
TL;DR: In this paper, the authors argue that a preference-based power index is incompatible with the definition of power as a generic ability: "the ability to affect outcomes" and claim that power resides in, and only in, a game form and not in a game itself.

A model of influence in a social network
TL;DR: This paper separates the influence part from the group decision part, and proposes among other descriptive tools a definition of a (weighted) influence index of a coalition upon an individual.

The concept of power
TL;DR: In this paper, the concept of power is defined in terms of a relation between people, and is expressed in simple symbolic notation, and a statement of power comparability is developed, or the relative degree of power held by two or more persons.

A Method for Evaluating the Distribution of Power in a Committee System
Lloyd S. Shapley,Martin Shubik +1 more
TL;DR: The method of measuring power, based on a technique of the mathematical theory of games, is presented here to a number of illustrative cases, including the United States Congress, and is intended as a first step in the attack on these problems.

Decision-Rules and Individual Values in Constitutional Choice
TL;DR: In this paper, the authors consider the problem of deciding how many members of a political community must agree before a policy is imposed on the community if participation is limited to one man.
