Dear Arjan, we have a paper about the impact of internet reviews on the trustworthiness of the seller: Utz, S., Matzat, U., & Snijders, C. (2009). "Online Reputation Systems: The Effects of Feedback Comments and Reactions on Building and Rebuilding Trust in Online Auctions." in: International Journal of Electronic Commerce, 13, 3: 95-118. In the list of references of this paper you find other studies, for instance: Pavlou, P. A. and Dimoka, A. The nature and role of feedback text comments in online marketplaces: implications for trust building, price premiums, and seller differentiation. Information Systems Research, 17, 4 (December 2006), 392414.
