Stable and efficient reallocations when preferences are single-dipped
研究一群拥有单谷偏好的代理人如何再分配一种不可丢弃的无限可分商品，刻画了满足个人理性或联盟理性的帕累托最优分配，并给出核心非空的充要条件。
Imagine a group of agents, each being endowed with a share of one unit of an infinitely divisible and non-disposable commodity. Each agent has single-dipped preferences. We characterize the Pareto optimal allocations that satisfy individual rationality or coalitional rationality. In particular, we show that Pareto optimal and individually rational allocations always exist, and we provide a necessary and sufficient condition for non-emptiness of the core.
