Vertrauen bei Internet-Auktionen

The text replies to the article “Trust and Reputation in Internet-Auctions” (KZfSS, Vol. 54, No. 4, pp. 674–693) by Diekmann and Wyder. In principle the authors’ consideration regarding a premium for reputation for trustworthy participants in internet auctions seems to be attractive. However, we object to the lacking definitions of the categories of trust and reputation as well as to the problematic design of their central indicator (reputation). With regard to their interpretation we criticize the missing consideration of qualitative — especially negative — statements in the public rating systems, underestimating the relevance of “critical incidents” to fragile trust relations on the internet. Finally we remark that Diekmann and Wyder misjudge the founding, cultivating and modifying activities (including imposing sanctions) of the platform owner towards this institution regulating the market.
