In particular, it has been used to estimate political power (Leech, 2002; Felsenthal et al., 1998).

Let SS i = number of sequential coalitions where P i is pivotal. The Shapley-Shubik power index of player P i is the fraction ˙ i = SS i total number of sequential coalitions. and the Shapley-Shubik power ...We now compare the Shapley-Shubik indices and the Banzhaf indices to show that they diﬀer for at least one divisor of n. We can show that each proper divisor of n, di, has a …
According 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. A coalition S S is the subset of N N with all ... Commodity money, oligopoly, credit and bankruptcy in a general equilibrium model. M Shubik. Economic Inquiry 11 (1), 24. , 1973. 347. 1973.
