Shapley shubik.

The Shapley-Shubik index is a measure of a voter's power in a weighted voting system. To calculate the index of a voter we first list all of the permutations of voters. If there are 3 voters there will be 3! = 6 permutations, with 4 voters there will be 4! = 24 permutations, and so forth. In each permutation the order plays an important role.Shubik is the surname of the following people .

She is pivot if she is second or third in a permutation. There are 4 such permutations: BAC, CAB, BCA, and CBA, and since 3! = 6, the Shapley-Shubik Power Index of A is 4/6 = 2/3. B and C share the remaining two permutations, so each has Shapley-Shubik power index equal to 1/6. Counting Problems. To calculate these power indices is a counting ...

In situations like political alliances, the order in which players join an alliance could be considered the most important consideration. In a weighted voting system with three players the winning coalitions are {P1, P2} and {P1, P2, P3}. List the sequential coalitions and identify the pivotal player in each sequential coalition.

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’).
