Existence of Walrasian equilibria with discontinuous, non-ordered, interdependent preferences, without free disposal, and with an infinite-dimensional commodity space
证明了在无限维商品空间中，即使偏好不连续、相互依赖且非有序，且无免费处置假设，瓦尔拉斯均衡仍然存在，推广了多个经典存在性结果。
Abstract A new proof of the existence of a Walrasian equilibrium with an infinite dimensional commodity space is provided, which allows agents’ preferences to be discontinuous. The new theorems include as corollaries the existence results of Mas-Collel, Yannelis and Zame, Araujo and Monteiro, and Mas-Collel and Richard, among others.
