Abstract

Liquid democracy encompasses a family of decision-making processes where votes can be cast directly or passed along proxy chains. We provide a community-maintainable and systematic survey of (computational) social choice papers on liquid democracy, organized through a searchable taxonomy of core modeling features that have appeared in the literature. Drawing on the insights from our survey, we also outline a number of research directions, which we consider of special importance for both the theory and practice of liquid democracy.
