Ade, Michelini & Vigiani (2022), Proportionality in Liquid Democracy and Representative Democracy

<h4><a href="https://figshare.com/projects/Proceedings_of_the_ESSLLI_2022_Student_Session/144189" target="_blank">Proceedings of the ESSLLI 2022 Student Session</a></h4> <h2>Proportionality in Liquid Democracy and Representative Democracy</h2> <h3>Leyla Ade, Matteo Michelini and Pietro Vigiani</h3> <p>In this paper, we compare liquid democracy to representative democracy with respect to a <em>proportionality principle</em>, according to which agents with higher stakes should have more voting weight. We provide a formal model of voting systems that models agents' uncertainty towards a voting issue as influenced by stakes in the issue. We formalise the delegation process in representative democracy and liquid democracy and prove that only the latter satisfies the proportionality principle.</p>
