number of alternatives for the group decision. A Shapley-Shubik power index for (3;2) simple games was introduced in [7, pp. 291{293]. When discussing the so-called roll call model for the Shapley-Shubik index, we will see that certain biases of the voters to \yes" or o"-votes do not matter for the Shapley-Shubik index for simple games. Martin Shubik. Martin Shubik (1926-2018) was an American mathematical economist who specialized in game theory, defense analysis, and the theory of money and financial institutions. The latter was his main research interest and he coined the term "mathematical institutional economics" in 1959 to describe it and referred to it as his "white ...

Brief Introduction (For a more complete explanation, see For All Practical Purposes, 10th Edition, New York, WH Freeman 2015, Chapter 11). A weighted voting system is a decision-making device with participants, called voters, who are asked to decide upon questions by "yea" or "nay" votes. Each voter is assigned a v oting weight.

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’). In a similar way, one is interested in evaluating a game; that is ...
