传统的市场均衡模型支持令人印象深刻的存在性结果,包括著名的阿罗-德布鲁定理。然而,在这个模型中,用于计算(或近似)均衡的多项式时间算法仅适用于线性效用函数。我们提出了一个新的,自然的,市场均衡模型,不仅承认存在性和唯一性的结果平行的传统模型,但也适合于有效的算法。
The traditional model of market equilibrium supports impressive existence results, including the celebrated Arrow-Debreu Theorem. However, in this model, polynomial time algorithms for computing (or approximating) equilibria are known only for linear utility functions. We present a new, and natural, model of market equilibrium that not only admits existence and uniqueness results paralleling those for the traditional model but is also amenable to efficient algorithms.
