If at First You Don't Succeed…: Profits, Prices, and Market Structure in a Model of Quality with Unknowable Consumer Heterogeneity*
构建了一个新的品质模型，探讨为何高品质利基市场利润更高、高品质产品有时低价而低品质产品罕见高价、市场能否同时存在品质分化与聚集，以及固定成本随品质变化如何影响市场结构。
Why are higher quality niches seen as intrinsically more profitable in business circles? Why do high quality products sometimes have a low real price, whereas it is unusual to see low quality products with high real prices? Can markets have quality differentiation as well as quality bunching? How does the rate at which fixed costs change with quality affect market structure? In this article we develop a new model of quality that casts light on such issues.
