When the members of a voting body exhibit single peaked preferences, majority winners exist. Moreover, the median(s) of the preferred alternatives of voters is (are) indeed the majority (Condorcet) winner(s). This important result of Duncan Black has been crucial in the development of public...

We study option management by committee. Analysis is illustrated by tenure decisions. Our innovations are two-fold: we treat the committee's problem as one of social choice, not information aggregation; and we endogenise the outside option: rejecting a candidate at either the probationary or...

Commercially speaking, law journalism was a risky business in the early Republic. According to Frederick Hicks, of the 30 legal periodicals that went into business before 1850, 24 also went out of business before 1850. And of the six that survived into the second half of the century, five...

We propose a boundedly-rational model of opinion formation where agents are subject to the phenomenon of persuasion. We argue that persuasion - whereby repeated exposure to an opinion has a cumulative effect on an agent's beliefs - is pervasive and closely related to the concept of social...

Nous exploitons dans cet article la théeorie des indices de pouvoir pour éevaluer les infuences 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,...

We establish a new suffcient condition for avoiding a generalization of the Anscombe’s paradox. In a situation where ballots describe positions regarding finitely many yes-or-no issues, the Anscombe’s alpha−paradox holds if more than alpha % of the voters disagree with on a majority of...

A new voting rule for electing committees is described. Specifically, we use approval balloting and propose a voting procedure guaranteeing that if a committee representing (in a determined proportion) all voters exists, then the selected committee has to represent all voters at least in the...

We study dominant strategy incentive compatible (DIC) and deterministic mechanisms in a social choice setting with several alternatives. The agents are privately informed about their preferences, and have single-crossing utility functions. Monetary transfers are not feasible. We use an...

Rules of k names are frequently used methods to appoint individuals to office. They are two-stage procedures where a first set of agents, the proposers, select k individuals from an initial set of candidates, and then another agent, the chooser, appoints one among those k in the list. In...
