英文摘要:
In a recent and ongoing work, Baldwin and Klemperer explored a connection between tropical geometry and economics. They gave a sufficient condition for the existence of competitive equilibrium in product-mix auctions of indivisible goods. This result, which we call the Unimodularity Theorem, can also be traced back to the work of Danilov, Koshevoy, and Murota in discrete convex analysis. We give a new proof of the Unimodularity Theorem via the classical unimodularity theorem in integer programming. We give a unified treatment of these results via tropical geometry and formulate a new sufficient condition for competitive equilibrium when there are only two types of product. Generalizations of our theorem in higher dimensions are equivalent to various forms of the Oda conjecture in algebraic geometry.

中文摘要:
在最近正在进行的一项研究中,鲍德温和克伦佩尔探索了热带几何学与经济学之间的联系。他们给出了不可分割商品的产品组合拍卖存在竞争均衡的充分条件。这个结果,我们称之为单模性定理,也可以追溯到Danilov、Koshevoy和Murota在离散凸分析中的工作。通过整数规划中的经典单模性定理,给出了单模性定理的一个新证明。我们通过热带几何学对这些结果进行了统一处理,并在只有两类产品的情况下给出了竞争平衡的一个新的充分条件。我们的定理在高维上的推广等价于代数几何中各种形式的Oda猜想。
