Evidence on Agglomeration in Quality Space
利用西德175种商品的测试数据，研究质量空间中的集聚现象，发现集聚是常态，市场通常能满足高需求但可能忽视低需求。
This paper is an empirical study of agglomeration in quality space. Data has been collected for 175 West German commodities that the consumer testing agency Test has tested on a number of quality characteristics for a number of brands for each commodity, thus providing product positions in quality space. The major findings are that agglomeration seems to be the norm rather than the exception, an d that the market does not usually fail consumers wanting a high-qualit y brand, but may fail consumers wanting a low-quality brand.
