阿罗和德布鲁(Arrow&Debru,1954)中的交易必须在零时刻集中进行。瑞德那(Radrer,1972)从时间角度对阿罗和德布鲁(Arrow&Debru,1954)中的交易结构进行了改造,本文将进一步从空间角度进行改造,即交易将是序贯分散进行的。分散后,每个子市场中的人数可能会很少,完全竞争假设将不适合。本文研究在分散的子市场中买卖双方将如何通过非完全竞争进行定价。本文证明,在一定条件下,分散定价的结果将向集中定价的结果收敛,并且存在均衡的偏唯一性。
The deals in Arrow and Debru (1954) must be concentrated at zero time. Radrer (1972) transformed the trading structure of Arrow and Debru (1954) from a temporal perspective. This article will further transform from a spatial perspective that the transaction will be sequential and decentralized. After decentralization, the number of people in each sub-market may be small and the perfect competition assumption will not fit. This paper investigates how buyers and sellers in a decentralized sub-market will price through imperfect competition. This paper proves that under certain conditions, the result of decentralized pricing will converge to the result of centralized pricing, and there exists a balanced partial uniqueness.
