In a symmetric information voting model, an individual (politician) can influence voters' choices by strategically designing a policy experiment (public signal). We characterize the politician's optimal experiment. With a nonunanimous voting rule, she exploits voters' heterogeneity by designing an experiment with realizations targeting different winning coalitions. Consequently, under a simple-majority rule, a majority of voters might be strictly worse off due to the politician's influence. We characterize voters' preferences over electoral rules and provide conditions for a majority of voters to prefer a supermajority (or unanimity) voting rule, in order to induce the politician to supply a more informative experiment.

AbstractWe conduct a laboratory experiment to study the incentives of a privileged group (the “yellows”) to share political power with another group (the “blues”). The yellows collectively choose the voting rule for a general election: a simple-majority rule that favors them, or a proportional rule. In two treatments, the blues can use a costly punishment option. We find that the yellows share power voluntarily only to a small extent, but they are more inclined to do so under the threat of punishment, despite the fact that punishments are not sub-game perfect. The blue group conditions punishments both on the voting rule and the electoral outcome.

AbstractDoes the accuracy of verdicts improve or worsen if individual jurors on a panel are barred from deliberating prior to casting their votes? I study this question in a model where jurors can choose to exert costly effort to improve the accuracy of their individual decisions. I find that, provided the cost of effort is not too large, it is better to allow jurors to deliberate if jury size exceeds a threshold. For panels smaller than this threshold, it is more effective to instruct jurors to vote on the basis of their private information, without deliberations, and to use a simple majority rule to determine the collective decision (regardless of the voting rule used with deliberations). The smaller the cost of paying attention, the larger the threshold above which the switch to allowing deliberations becomes optimal. However, if the unanimity rule had to be maintained under the no-deliberations system, it would be better to allow deliberation. The results apply to binary decision making in any committee where the committee members incur some effort in reviewing the evidence. Examples are arbitration panels and tenure and promotion committees and some board of director meetings on issues such as whether to dismiss a CEO. As an extension I consider the case where jurors differ in their costs of effort.

In this paper we provide an analysis of the Commission's proposal of so called double simple majority rule (when to pass a decision simple majority of Member States and at the same time simple majority of total population has to be reached) for the voting in the Council of Ministers of the EU. In our evaluation we are using an a priori voting power methodology to measure an influence of the Member States before and after extension of the EU. In the closing part of the paper we shortly compare the double simple majority rule to the compromise approved by the 2000 Nice Summit of the EU.

Simple majority rule is badly behaved. This is one of the earliest lessons learned by political scientists in the positive political theory tradition. Discovered and rediscovered by theorists over the centuries (including, famously, the Majorcan Franciscan monk Raymon Llull in the thirteenth century, the Marquis de Condorcet in the eighteenth, the Reverend Charles Dodgson (Lewis Carroll) in the eighteenth, and Duncan Black in the twentieth), the method of majority rule cannot be counted on to produce a rational collective choice. In many circumstances (made precise in the technical literature), it is very likely (a claim also made precise) that whatever choice is produced will suffer the property of not being “best” in the preferences of all majorities: for any candidate alternative, there will always exist another alternative that some majority prefers to it. This chapter suggests that while a collection of preferences often cannot provide a collectively “best” choice, institutional arrangements, which restrict comparisons of alternatives, may allow majority rule to function more smoothly. That is, where equilibrium induced by preferences alone may fail to exist, institutional structure may induce stability.

This chapter details the likely economic, democratic, and rights performance of a decentralized national legislature with representatives elected from geographically specified local districts. The national legislature is assigned responsibility for national public goods and services and national regulations. Decisions in the legislature are made by simple majority rule. Independent local governments continue to be responsible for important local services, perhaps provided concurrently with the national government. On the dimensions of democratic participation and the protection of rights and liberties, Democratic Federalism is likely to do well, provided all citizens are represented in the legislature. It is on the dimension of economic efficiency that legislature-only Democratic Federalism is most likely to fall short.

Sapir (1998) calculated the probabilities of the expert rule and of the simple majority rule being optimal under the assumption of exponentially distributed logarithmic expertise levels. Here we find the analogous probabilities for the family of restricted majority rules, including the above two extreme rules as special cases, and the family of balanced expert rules. We compare the two families, the rules within each family, and all rules of the two families with the extreme rules.

Roughly two centuries ago the Marquis de Condorcet and Chevalier Jean-Charles de Borda originated a research tradition – by no means a continuous one – that over the decades has produced results casting doubt on many widely used collective decision-making procedures. The phenomenon known as the Condorcet effect or the Condorcet paradox is the well-known problem of the simple majority rule. The paradox bearing the name of Borda is less commonly known, but it also relates to a procedure that is widely used, namely the plurality principle. Either one of these paradoxes is serious enough to make these procedures suspect unless one is convinced that the situations giving rise to these paradoxical features are extremely rare. In this article we review some voting procedures that have been introduced in the literature. We aim at giving a synthesis of the assessments of procedures with respect to various criteria.
