一个模型的产品差异化相结合的空间和代表性的消费者配方的元素被用来检查单一和多重价格均衡的属性。给出了消费者偏好强度下降导致价格下降的条件。它表明，与某些类型的需求曲线，进入可以消除价格成本加价，即使产品差异化。如果竞争是本地化的，则表明进入并不影响加价。最后，虚假的产品差异化对价格的影响进行了研究。
A model of product differentiation which combines elements of both spatial and representative consumer formulations is used to examine the properties of single- and multiple-price equilibria. Conditions under which decreases in the intensity of consumer preferences reduce price are given. It is shown that, with certain types of demand curves, entry can eliminate price-cost markups even given product differentiation. If competition is localized, it is demonstrated that entry does not affect the markup. Finally, the effect of spurious product differentiation on price is examined.
