Non-Existence of PMMS Allocations and a -PMMS Guarantee for Additive Chores
Xiaohui Bei, Zehan Lin, Shengxin Liu +2
We study pairwise maximin share (PMMS) fairness for indivisible items with additive preferences. We give a polynomial-time reduction from chores to goods that preserves the existen…
Individual Fairness in Budget Aggregation
Xiaohui Bei, Felix Brandt, Matthias Greger +3
We consider the problem of aggregating individual distributions over alternatives into a collective distribution, also known as budget aggregation. Existing fairness notion…
Fair Division by Contribution: A Shapley Value Perspective
Xiaohui Bei, Pinyan Lu, Xiaowei Wu +1
In many resource allocation problems, agents' valuations are best interpreted not as subjective preferences, but as the value they generate from receiving resources. Such valuation…
EconCSLib: A Lean Library for Computational Economics and AI-Assisted Research
Xiaohui Bei, Jiajun Ma, Zhan Jing +2
Mathematical formalization uses interactive theorem provers to turn informal mathematical statements into machine-checkable artifacts. The success of mathlib, a large collaborative…
Approximate Maximin Share with Subjective Divisibility: Beating the 1/2 Barrier
Xiaohui Bei, Ke Ding, Bo Li +1
Maximin share (MMS) stands out as a central notion in fair resource allocation. It is known that exact MMS fairness is not always attainable, especially when agents differ along tw…
Welfare Loss in Connected Resource Allocation
Xiaohui Bei, Alexander Lam, Xinhang Lu +1
We study the allocation of indivisible items that form an undirected graph and investigate the worst-case welfare loss when requiring that each agent must receive a connected subgr…
