Davide Grossi presented the paper Power in Liquid Democracy: A Network Centrality Approach at the 3rd Workshop on New Directions in Social Choice, co-located with the ACM Conference on Economics and Computation (EC 2026) in Rome, Italy.
The paper, co-authored by Davide Grossi, Andreas Nitsche, Georgios Papasotiropoulos, Oskar Skibski, Piotr Skowron, and Tomasz Wąs, investigates how power and influence can be measured in liquid democracy systems with transitive and suspendable delegations.
The work develops a new approach based on expected voting weight and network centrality, taking into account that participants can vote directly and thereby suspend their delegations.
The paper is available as a preprint.
