Endowments, Exclusion, and Exchange
提出排他核作为离散交换经济的新解概念，将禀赋重新解释为排他权分配，适用于有条件的产权、共同所有权和社会等级制度，并用广义顶环算法刻画。
We propose a new solution for discrete exchange economies and resource‐allocation problems, the exclusion core. The exclusion core rests upon a foundational idea in the legal understanding of property, the right to exclude others. By reinterpreting endowments as a distribution of exclusion rights, rather than as bundles of goods, our analysis extends to economies with qualified property rights, joint ownership, and social hierarchies. The exclusion core is characterized by a generalized top trading cycle algorithm in a large class of economies, including those featuring private, public, and mixed ownership. It is neither weaker nor stronger than the strong core.
