Spatial Price Discrimination in Agricultural Product Procurement Markets: A Computational Economics Approach
针对农产品采购市场中因运输成本与空间分布导致的寡头垄断，提出计算经济学模型分析企业如何选择空间定价策略，发现买方更倾向于通过统一交货定价或部分运费吸收来实现价格歧视。
Significant transport costs and spatially distributed supply and processing create oligopsony power in agricultural markets. Price discrimination expressed in the form of partial or complete absorption of freight charges by processors is often observed in these environments, but we understand little about how these pricing decisions are made. Analytical approaches are often intractable. As an alternative, we propose a computational economics approach to analyze a general spatial competition model and study firms' choices of spatial pricing policy. Instead of the commonly presumed free‐on‐board pricing, we find that buyers choose price discrimination, either through uniform delivered pricing or through partial freight absorption.
