Almost Envy-Freeness for Additive Mixed Manna with Entitlements: Deterministic and Randomized Guarantees

Zehan Lin, Shengxin Liu, Biaoshuai Tao +1

We investigate the fair allocation of indivisible items among agents with asymmetric entitlements in mixed manna settings, where the items consist of both goods and chores. For add…

Non-Existence of EFX Chore Allocations for Monotone Cost Functions with Binary Marginals

Zehan Lin, Shengxin Liu, Biaoshuai Tao +1

We study the existence of envy-free up to any item (EFX) allocations of indivisible chores when agents have monotone cost functions with binary marginals. For indivisible goods, th…

Bayesian Fair Division: Truthfulness in Picking Sequence with Correlated Valuations

Xiaolin Bu, Biaoshuai Tao

Sequential allocation mechanisms contain a class of widely studied mechanisms (e.g., round-robin) in the fair division of indivisible goods, where agents take turns picking items i…

Limitations of Best-of-Both-Worlds Solutions in Approval-Based Multiwinner Elections

Jiarong Jin, Xuanxuan Liu, Biaoshuai Tao

We study the best-of-both-worlds fairness in approval-based multi-winner elections, asking whether ex-ante guarantees for a fractional outcome can be implemented while every realiz…
