Spatial Price Discrimination in Two‐Dimensional Competitive Markets
直觉认为能实施价格歧视的企业利润更高，但本文通过二维空间模型证明，在一般情形下并非如此，并分析了运输成本、竞争与定价策略的相互作用。
Intuition suggests that firms that can apply price discrimination make higher profits than firms that are restricted in their pricing policy. In this paper, we show that, in general, this is not the case. In the framework of a two‐dimensional spatial model with elastic demand à la Lösch, we further investigate the interplay of transport costs, competition, and price policy. One of our results is that under realistic specifications of parameters each firm gains a monopolistic area in the center of its market that has the same shape as the entire market, but with a convexly or concavely distorted separating line, depending on the extension of the market.
