Weighted Fair Division: Additive Preferences and Beyond
September 17, 2024 3:30 PM Singapore (Registration starts at 3:20 PM)
Abstract
Fair resource allocation is a fundamental problem in society, with applications ranging from inheritance division to ministry allocation. While the fair division literature typically assumes that all agents have the same entitlement to the resource, several practical applications involve agents with varying entitlements represented by weights. I will present the highlights of my work on weighted fair division of indivisible resources, which include (i) adapting standard fairness notions such as envy-freeness and proportionality to the weighted setting; (ii) generalizing prominent allocation algorithms such as picking sequences and maximum Nash welfare to incorporate weights; and (iii) analyzing algorithms with respect to axiomatic properties including fairness, monotonicity, and strategyproofness. I will also discuss the progress and challenges of extending the results beyond additive preferences.
