不可分割物品的民主公平分配

Democratic Fair Allocation of Indivisible Goods

Erel Segal-Halevi, Warut Suksompong

摘要:

我们研究的问题,公平分配不可分割的商品组的代理商。同一组中的代理人共享同一组商品,即使他们可能有不同的偏好。以前的工作集中在一致公平,其中每个组中的所有代理必须同意他们组的份额是公平的。在这种严格的要求下,公平分配只存在于小团体。我们引入了民主公平的概念,其目的是满足一定比例的代理在每个组。这个概念更适合城市或国家等大型群体。我们提出了两个或两个以上的任意大组的代理人与单调,添加剂,或二进制估值之间的民主公平分配协议。对于两组任意单调赋值,我们给出了一个有效的协议,保证envy-freeness高达一个好的至少$1/2$的代理在每个组中,并证明了$1/2$分数是最优的。我们还提出了其他协议,使较弱的公平性保证更多的代理在每个组中,或更多的群体。我们的协议结合了来自不同领域的技术,包括组合博弈论,蛋糕切割和投票。

英文摘要:

We study the problem of fairly allocating indivisible goods to groups of agents. Agents in the same group share the same set of goods even though they may have different preferences. Previous work has focused on unanimous fairness, in which all agents in each group must agree that their group's share is fair. Under this strict requirement, fair allocations exist only for small groups. We introduce the concept of democratic fairness, which aims to satisfy a certain fraction of the agents in each group. This concept is better suited to large groups such as cities or countries. We present protocols for democratic fair allocation among two or more arbitrarily large groups of agents with monotonic, additive, or binary valuations. For two groups with arbitrary monotonic valuations, we give an efficient protocol that guarantees envy-freeness up to one good for at least $1/2$ of the agents in each group, and prove that the $1/2$ fraction is optimal. We also present other protocols that make weaker fairness guarantees to more agents in each group, or to more groups. Our protocols combine techniques from different fields, including combinatorial game theory, cake cutting, and voting.
