Liquid Democracy with Ranked Delegations

On Rational Delegations in Liquid Democracy

Liquid democracy is a proxy voting method where proxies are delegable. We propose and study a game-theoretic model of liquid democracy to address the following question: when is it rational for a voter to delegate her vote? We study the existence of pure-strategy Nash equilibria in this model, and how group accuracy is affected by them. We complement these results by means of simulations to stu...

Liquid Democracy: An Algorithmic Perspective

We study liquid democracy, a collective decision making paradigm that allows voters to transitively delegate their votes, through an algorithmic lens. In our model, there are two alternatives, one correct and one incorrect, and we are interested in the probability that the majority opinion is correct. Our main question is whether there exist delegation mechanisms that are guaranteed to outperfo...

Binary Voting with Delegable Proxy: An Analysis of Liquid Democracy

The paper provides an analysis of the voting method known as delegable proxy voting, or liquid democracy. The analysis first positions liquid democracy within the theory of binary aggregation. It then focuses on two issues of the system: the occurrence of delegation cycles; and the effect of delegations on individual rationality when voting on logically interdependent propositions. It finally p...

Delegations and Trust

One of the fundamental notions in a multiagent system is that of delegation. Delegation forms the foundation for cooperation and collaboration among the members of a multiagent system. In diverse environments such as those formed by open multiagent systems, the various members constituting the environment are customarily alien to one another. Delegation decisions in such environments are necess...
