Testing a Spatial Interacting-Markets Hypothesis
提出两个城市零售店空间竞争定价模型，区分市场供需关系和竞争空间形态，并用汽油零售价格数据在价格涨跌期进行拟合检验。
Two models for competitive spatial pricing between retail outlets in a single urban area are presented. The models are distinguished in terms of first, their relationships to underlying supply and demand conditions in the market and second, the spatial forms of inter-site competition described. Properties of the models are identified. The statistical theory appropriate to these models is reviewed and the models then fitted to data for retail gasoline prices during periods of falling and then rising average price levels.
