Category Signaling and Reputation
提出当低质量生产者获取类别成员资格的成本更高时，类别成员资格可作为质量的集体市场信号，并以阿尔萨斯生物动力和有机葡萄栽培为例进行实证研究。
We propose that category membership can operate as a collective market signal for quality when low-quality producers face higher costs of gaining membership. The strength of membership as a collective signal increases with the sharpness of the category boundary, that is, contrast. Our empirical study focuses on biodynamic and organic viticulture in Alsace.
