“Abstention, multiple issues, and the Banzhaf power index”

(joint work Hans Peters)

This paper considers voting systems in which abstention is possible, and in which the power of coalitions may depend on the issues under consideration. A class of issue-based Banzhaf power indices is axiomatically characterized for such systems. As a by-product, this approach also yields several new characterizations of (nonnegative multiples of) the Banzhaf power index. Examples are included to show how the indices behave.
