The Eurovision Song Contest is one of the worldwide biggest live media events and the world’s leading broadcast of an international music competition. The countries of the European Broadcasting Union participate by sending an artist (or a group of artists) to the contest and both expert juries...

We estimate 3% of the U.S. voter population is registered to vote in two states. Which state these double-registrants choose to vote in reflects incentives and costs, being more prevalent in swing states (higher incentive) and states which automatically send out mail-in ballots (lower cost). We...

In the United States, electoral districts must be equipopulous. This requirement is known as the one man one vote doctrine. We propose welfare-based justifications for this requirement under the economic view, according to which voters care about the policy, and under the political view,...

This research project investigates whether one of the purported benefits of Ranked Choice Voting (RCV) – an expanded candidate pool – has been realized in the cities where it has been implemented. Employing a difference-in-differences approach with matching, I find that any increase in the...

In a functioning democracy, the legitimacy of government rests on citizens' confidence in the political system and its decisions. The ability to express preferences and consider these preferences in decision-making is a critical aspect of democracy. This study investigates the impact of voting...

We critically discuss the Jefferson/D'Hondt and Webster/Sainte-Laguë methods, which are used to allocate parliament seats to parties in the mixed-member proportional representation systems in Germany, New Zealand, Bolivia, South Africa, South Korea, Scotland and Wales, as well as in the...

We generalize the standard, private values voting model with single-peaked preferences and incomplete information by introducing interdependent preferences. Our main results show how standard mechanisms that are outcome-equivalent and implement the Condorcet winner under complete information or...

The Qualified Majority Voting (QMV) used by the Council of the European Union developed to a high degree of complexity from one modifying treaty to another, until the latest definition stipulated in the Treaty of Lisbon. This paper analyses this EU intra-institutional voting method using a...

Experts' voting behavior is conjectured to be more objective than peer voting (own group/peers) and public voters (everyone interested), who are supposedly influenced by all sorts of subjective aspects. We examine differences in voting behavior between these groups by analyzing the voting...

The Eurovision Song Contest is one of the worldwide biggest live media events and the world’s leading broadcast of an international music competition. The countries of the European Broadcasting Union participate by sending an artist (or a group of artists) to the contest and both expert juries...

This paper introduces a new storable vote mechanism (storable votes, pay-as-you-win-mechanism, SV-PAYW) where a fixed number of votes can be cast among different alternatives, and the votes spent (and redistributed) on each election depend only on the number cast for the wining alternative. The...

Complex and important policy decisions are often made with advice from a committee of experts, where experts first convene and discuss, before finalizing their collective decision with a vote. We show that the voting structure (whether the experts vote sequentially or simultaneously) plays a...

Across many contexts, majority rules are used as a decision-making procedure to coordinate conflicts within groups. Despite the prevalence of majority rules procedures, it is unclear how children think about majority rules as a way to resolve group disagreements in early childhood, and how this...

Political polarization in the United States has increased dramatically, hampering the functioning of American government. Some scholars attribute this dynamic to the use of plurality elections and posit that a ranked choice voting (RCV) system may promote greater bipartisanship. Maine’s 2016...

Under majoritarian election systems, securing participation and representation of minorities remains an open problem, made salient in the US by its history of voter suppression. One remedy recommended by the courts is Cumulative Voting (CV): each voter has as many votes as open positions and can...

This article aims to provide a comprehensive overview of the different voting schemes used in DAO governance. We will examine the various features of these schemes and compare their differences. We propose a new hypothetical voting mechanism specifically designed for decentralized and...

ChatGPT has risen rapidly to prominence due to its unique features and generalization ability. This article proposes using ChatGPT to assist small investment funds, particularly small passive funds, in making more accurate and informed proxy voting decisions.Passive funds adopt a low-cost...

We consider a committee that consists of n members with one person one vote approving a proposal if the number of affirmative votes from the members reaches threshold k. Which threshold k between 1 and n is "good" for the committee? We suppose that if a new threshold k' proposed by some...

Traditionally, fund managers cast votes on behalf of investors whose capital they manage. Recently, this system has come under intense debate given the growing concentration of voting power among a few asset managers and disagreements over environmental and social issues. Major fund managers now...

We characterize voting procedures according to the social choice correspondence they implement when voters cast ballots strategically, applying iteratively undominated strategies. In elections with three candidates, the Borda Rule is the unique positional scoring rule that satisfies 'unanimity'...

We study the effect on the participation rate of employing different voting rules in the context of the problem to allocate a fixed monetary budget to two different public projects. Specifically, we compare the mean rule according to which the average of the individually proposed allocations is...

The modern Condorcet jury theorem states that under weak conditions, when voters have common interests, elections will aggregate information when the population is large, in any equilibrium. Here, we study the performance of large elections with population uncertainty. We find that the modern...

In the debate on how to strengthen the European Union’s (EU) capacity to act, calls for an extension of qualified majority voting (QMV) are growing louder. The Council of the EU is currently discussing using the so-called passerelle clauses in the Treaty on European Union (TEU). With these...

We develop a numerical model that simulates the evolution of a virtual population with an incentive and ability-based wage, capital yield from savings, social welfare system, and total income subject to taxation and political turnovers. Meta-heuristics, particle swarm optimization (PSO) in...

This paper deals with the problem of calculating the Shapley-Shubik power index in weighted majority games. We propose an efficient Monte Carlo algorithm based on an implicit hierarchical structure of permutations of players. Our algorithm outputs a vector of power indices preserving the...

We study the efficient computation of power indices for weighted voting games with precoalitions amongst subsets of players (reflecting, e.g., ideological proximity) using the paradigm of dynamic programming. Starting from the state-of-the-art algorithms for computing the Banzhaf and...

Debates on an EU-leaving referendum arose in several member states after Brexit. We want to highlight how the exit of an additional country affects the power distribution in the Council of the European Union. We inspect the power indices of the member states both with and without the country...

This paper investigates the effects of members' exits from a currency union on the credibility of the common currency. In our currency union model, the inflation rate of the common currency is determined by majority voting among N member countries that are heterogeneous with respect to their...

In a model of simultaneous voting, Feddersen and Pesendorfer (1998) consider the possibility that jurors vote strategically, rather than sincerely reflecting their individual information. This results in the counterintuitive result that a jury is more likely to convict the innocent under a...

Homophily in Voting Behavior: Evidence from Preferential Voting Abstract: Homophily is a strong determinant of many types of human relationships. It affects, for example, whom we marry and potentially also whom we vote for. We use data on preferential voting from Czech parliamentary elections in...
