# Proxy Voting for Better Outcomes

@article{Cohensius2017ProxyVF, title={Proxy Voting for Better Outcomes}, author={Gal Cohensius and Shie Mannor and R. Meir and Eli A. Meirom and Ariel Orda}, journal={ArXiv}, year={2017}, volume={abs/1611.08308} }

We consider a social choice problem where only a small number of people out of a large population are sufficiently available or motivated to vote. A common solution to increase participation is to allow voters use a proxy, that is, transfer their voting rights to another voter. Considering social choice problems on metric spaces, we compare voting with and without the use of proxies to see which mechanism better approximates the optimal outcome, and characterize the regimes in which proxy…

Representative Committees of Peers

It is demonstrated that the k-sortition is the worst-case optimal rule within a broad family of committee-based rules that take into account metric information about the preference profile of the whole population.

Representative Proxy Voting

- Economics, Computer ScienceAAAI
- 2021

A model of proxy voting where the candidates, voters, and proxies are all located on the real line, and instead of voting directly, each voter delegates its vote to the closest proxy is studied, showing that for candidates located on a line, an optimal proxy arrangement can be computed in polynomial time.

Proxy selection in transitive proxy voting

- EconomicsSoc. Choice Welf.
- 2022

This paper proposes a new social choice-theoretic model of liquid democracy, which is distinguished by taking a richer formal perspective on the process by which a voter chooses a proxy, and explores the topic of manipulation in transitive proxy votes.

Primarily about Primaries

- EconomicsAAAI
- 2019

This work presents a model to analyze multi-stage elections, and conducts the first quantitative comparison (to the best of the knowledge) of the direct and primary voting systems with two political parties in terms of the quality of the elected candidate.

Liquid Democracy: An Algorithmic Perspective

- Economics, Computer ScienceAAAI
- 2018

It is shown that local delegation mechanisms, which only take the local neighborhood of each voter as input (and, arguably, capture the spirit of liquid democracy), cannot provide the foregoing guarantee, and design a non-local delegation mechanism that does provably outperform direct voting under mild assumptions about voters.

A Mathematical Model for Optimal Decisions in a Representative Democracy

- EconomicsNeurIPS
- 2018

This work introduces a mathematical model for studying representative democracy, in particular understanding the parameters of a representative democracy that gives maximum decision making capability.

Incorporating Preference Information into Formal Models of Transitive Proxy Voting

- Economics
- 2019

This thesis is concerned with giving a computational social choice-theoretic model of transitive proxy voting. Transitive proxy voting (or ‘liquid democracy’) is a novel form of collective decision…

Evaluating Committees for Representative Democracies: the Distortion and Beyond

- EconomicsIJCAI
- 2020

In this model, a group of representatives is elected to make a series of decisions on behalf of voters based on the preferences of the voters over the candidates, and qualities of various multiwinner election rules are assessed.

In Defense of Fluid Democracy

- Computer ScienceArXiv
- 2021

The concerns raised about fluid democracy can be overcome, thereby bolstering the case for this emerging paradigm and demonstrating that delegations can be treated as stochastic processes and that they can be compared to wellknown processes from the literature that are sufficiently bounded for their purposes.

It is shown that if not only a committee, but also an election rule used to make final decisions, to depend on the voters' preferences, the authors can obtain an even better representation of the voters.

An axiomatic argument for a hybrid of direct democracy and representative democracy in which each citizen may vote directly on each issue, or delegate his vote on any issue to a representative (that is, a proxy) of his own choosing is constructed.

Ranked Voting on Social Networks

- EconomicsIJCAI

This work establishes a general framework -- based on random utility theory -- for ranked voting on a social network with arbitrarily many alternatives, and identifies a family of voting rules which, without knowledge of the social network structure, are guaranteed to recover the ground truth with high probability in large networks.
