Abstract We analyze and evaluate the different decision rules describing the Council of Ministers of the EU starting from 1958 up to date. All the existing studies use the Banzhaf index (for binary voting) or the Shapley-Shubik index (for distributive politics). We argue that the nucleolus can be considered an appropriate power measure in distributive situations and an alternative to the Shapley-Shubik index. We then calculate the nucleolus and compare the results of our calculations with the conventional measures. In the second part, we analyze the power of the European citizens as measured by the nucleolus under the egalitarian criterion proposed by Felsenthal and Machover (1998), and characterize the first best situation. Based on these results we propose a methodology for the design of the optimal (fair) decision rules. We perform the optimization exercise for the earlier stages of the EU within a restricted domain of voting rules, and conclude that Germany should receive more than the other three large countries under the optimal voting rule. * We would like to thank Moshé Machover, Josep Freixas and participants in the 10th international meeting of the society for Social Choice and Welfare for helpful comments.

In this paper, we introduce a su¢ cient condition on the domain of admissible preferences of a social choice mechanism under which the properties of individual and coalitional strategyproofness are equivalent. Then, we illustrate the usefulness of this general result in the case where a …xed budget has to be allocated among several pure public goods.
In this paper, we analyse the equilibrium of a sequential game-theoretical model of lobbying, based on Groseclose and Snyder (1996), describing a legislature that votes on two alternatives and two opposing lobbies, lobby 0 and lobby 1, that compete by bidding for legislators'votes. In this model there is a strong second-mover advantage, so the lobbyist moving …rst will make o¤ers to legislators only if he deters any credible counter-reaction from his opponent, i.e. if he anticipates winning the battle. Our main focus is on the calculation of the smallest budget that he needs to win the game and on the distribution of this budget across the legislators. We study the impact of game's key parameters on these two variables and show the connection of this problem with the combinatorics of sets and notions from cooperative game theory.We would like to thank Ron Holzman, Peter Sudhölter and seminar audiences in Leuven and Toulouse.
