There is no simple analytical relationship between the Shapley- Shubik index and the Banzhaf or Coleman indices. Like the Banzhaf index, the Shapley-Shubik index gives normalized power values that sum to 1 for all members of a weighted voting body. 9 Unlike the Coleman indices, the Shapley-Shubik index does not distinguish between …This problem has been solved!

The Shapley-Shubik Power Index Differs from Banzhaf Power Index: order of the players is important Who joined the coalition first? Example: Under the Banzhaf method, {P 1,P 2,P 3} is the same as {P 3,P 1,P 2}. Under Shapley-Shubik, these are different coalitions. Change in notation: Use hP 1,P 2,P 3i for sequential coalitionAccording to this paper Penrose (aka Banzhaf) and Shapley-Shubik power indices always rank the players in the same way. That makes it at least "more likely" for normalized Penrose and Shapley-Shubik indices to coincide. For players i = 1, 2, …, n i = 1, 2, …, n let N N be the set of all players.
