power indices
Definition
- If a group of persons—an assembly, for example, a committee—makes decisions by vote, one may wish to measure various types of voting power of the group as a whole or of any of its members: for example, the a priori probability that a given voter will be decisive in a division (i.e., the collective act of voting), or the value of a particular voter's vote to a potential briber, or the probability of an act being passed by the assembly. The need for voting power indices is twofold, having both prescriptive and descriptive purposes. [Source: Encyclopedia of Power; Power Indices]
