THE EFFECT OF GROUP SIZE AND ASYMMETRIES ON THE INCENTIVE TO REVEAL GROUP‐SPECIFIC INFORMATION*
研究了企业通过揭示产品属性真实信息来差异化产品的激励如何随消费者偏好分布变化，发现即使没有规模经济，信息也倾向于为大规模群体提供，且群体相对规模（不对称性）是信息盈利性的重要决定因素。
In this paper, I examine how firms' incentives to differentiate their products through the revelation of truthful information about product attributes varies with the distribution of consumer preferences for those attributes. I show that information will tend to be provided for large groups, even absent scale economies in producing that information. In addition, the relative sizes of the groups whose estimates of product quality change positively vs. negatively (i.e., the degree of asymmetry) by the information is likewise an important determinant of its profitability.
