本文阐述了另一种建模搜索摩擦的方法。摩擦不被假设存在，但被证明是作为一组对应于特定参数值范围的平衡的独特特征内生产生的。模型的空间结构和智能体的移动决策被明确地阐明，允许发生的接触数量取决于智能体选择定位自己的方式。一个聚合匹配函数被证明是存在的，它的行为与参数的变化有关，如地点之间的距离，代理的报酬，以及市场两边的搜索者群体的大小是完全表征的。
This paper illustrates an alternative approach to modeling search frictions. Frictions are not assumed to exist, but are shown to arise endogenously as a distinctive feature of the set of equilibria that correspond to a particular range of parameter values. The model’s spatial structure and the agents’ moving decisions are explicitly spelled out, allowing the number of contacts that occur to depend on the way agents choose to locate themselves. An aggregate matching function is shown to exist, and its behavior with respect to changes in parameters such as distances between locations, the agents’ payoffs, and the sizes of the populations of searchers on each side of the market is completely characterized.
