In this article we employ the theory of power indices to evaluate the respective influence of the two classes of electors in the polling method introduced by the electoral law of 29 June 1820, a method known as the law of “double vote”. We will show, using amplified model, that the voting...

In a federal union, a referendum paradox occurs each time a decision taken by representatives elected in separate jurisdictions (districts, states, regions) conflicts with the decision that would have been adopted if the voters had directly given their opinion via a referendum (Nurmi 1999)....

This article provides detailed results of computer simulation related to a theoretical work led by Le Breton and Lepelley [2011]. Particularly, we try to enlight results that can not be reached with analytical tools. Classification JEL : D71, D72.

An Excess-Voting Function relative to a profile assigns to each pair of alternatives (x,y), the number of voters who prefer x to y minus the number of voters who prefer y to x. It is shown that any non-binary separable Excess-Voting Function can be achieved from a preferences profile when...
