Effects of Evaluation Information Disclosure in E-Commerce Systems

This paper focuses on an incentive model to enhance information disclosure from sellers in e-shopping site. In existing e-commerce website, user rating is shown as simple form such as only total rating or combination of some attributes rating. We propose a new rating mechanism in which seller declares attributes. The e-commerce system provides extra point with information disclosure degree for seller. On the other hands, in marketplace, there are a lot of types of buyers. Our simulation shows how sellers make their appropriate strategies with distribution of buyer´s type in marketplace.
