We analyze and evaluate the different decision rules describing the Council of Ministers of the EU starting from 1958 up to now. Most of the existing studies use the Banzhaf index (for binary voting) or the Shapley-Shubik index (for distributive politics). We argue in favor of the nucleolus as a...

We study the political economy of urban traffic policy. We consider a city and its suburbs. The city decides, by majority voting, on a parking charge in the Central Business District (CBD) and restrictions on road space dedicated to cars. City and suburbs vote on road pricing in the CBD. Results...

The capacity to trust wisely is a critical facilitator of success and prosperity, and it has been conjectured that people of higher intelligence were better able to detect signs of untrustworthiness from potential partners. In contrast, this article reports five Trust Game studies suggesting that...

Nous exploitons dans cet article la théeorie des indices de pouvoir pour évaluer les influences respectives des deux classes d’électeurs dans le mode de scrutin instauré par la loi électorale du 29 juin 1820, dite loi du "double vote". Nous montrons, à l’aide d’un modèle simplifié, que le pouvoir...
