Electoral thresholds in the context of parliamentary elections are an instrument for preventing the fragmentation of parliaments and facilitate the formation of a coalition government. However, the clauses also introduce distortions and modify the equality of electoral votes in an election. In...

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 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...

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...

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...

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...

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...

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...

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...

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...

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 propose a new single-winner voting system using ranked ballots: Stable Voting. The motivating principle of Stable Voting is that if a candidate A would win without another candidate B in the election, and A beats B in a head-to-head majority comparison, then A should still win in the election...

We study pre-vote interactions in a committee that enacts a welfare-improving reform through voting. Committee members use decentralized promises contingent on the reform enactment to influence the vote outcome. Equilibrium promises prevent beneficial coalitional deviations and minimize total...

Under simple majority voting an absolute majority of voters may choose policies that are harmful to minorities. It is the purpose of sub- and super-majority rules to protect legitimate minority interests. We study how voting rules are chosen under the veil of ignorance. In our experiment,...

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...

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...

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...

Consider a setting in which individual strict preferences need to be aggregated into a social strict preference relation. For two alternatives and an odd number of agents, it follows from May’s Theorem that the majority aggregation rule is the only one satisfying anonymity, neutrality, and...

Olonite 2/3.5 Rule (O2/3.5R) is a selection rule employed to reduce the stress of researchers who are to sample a large population while maintaining the optimal selection from the large population. Using a three sampling/selection techniques, the result showed that the Olonite 2/3.5 Rule gives a...

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...
