for Shapley–Shubik power index and banzhaf power index,
If there is dummy voter A, then SSI(A) and BI(A) have got to be 0?
is there any counter example to it?
I think there is no counter example to it.
because if Either one of them is not equal to zero, then there might be some coalitions where Dummy voter A is pivotal, but It is against the definition of dummy.
anyone?
