Abstract
Each day, a countless number of items is sold through online auction sites such as eBay and Ricardo. Though abuse is being reported more and more, transactions seem to be relatively hassle free. A possible explanation for this phenomenon is that the sites' reputation mechanisms prevent opportunistic behavior. To analyze this issue, we first summarize and extend the mechanisms that affect the probability of sale of an item and its price. We then try to replicate the results as found in four recent papers on online auctions. Our analyses reveal that (1) it makes sense to differentiate between 'power sellers' and the less regular users, (2) there are variables that have an effect on sales that are often not controlled for, (3) one should carefully consider how reputation is operationalized, ( 4) neglecting heteroscedastidty in the data can have serious consequences, and (5) there is some support indicating that effects differ across auction sites.

The aim of this article is to demonstrate how harmonization of private law especially in the field of European Directives on E-commerce and distance contracts is working in the market of Internet Auctions where parties are contracting without intermediaries. The authors have chosen the topic of Internet Auctions because it is a very important modality to sell goods through the Internet, easily crossing borders of national sovereignty.
First of all, the authors give an overview over the existing Internet Auction models and the way of concluding contracts in such an Auction. Then, they provide an overview over the relevant European Directives in the field of Internet Auctions, the implementation of the Directives in the different national legal systems and the related national case law.Several differences between Italy and Germany are highlighted. One of these differences is the way to solve disputes between consumers: in Germany, these disputes are decided by courts while in Italy the solution is found through Alternative Dispute Resolution. Despite all the differences, several similarities are identified, like the desire to monitor transactions in E-commerce. In the end, each system can benefit from the results found in the other.

"Game Theory Bargaining and Auction Strategies bridges the gulf between the theoretical economic principles of negotiation and auction theory and explores the multifaceted applications of these principles in practice. The book provides a comprehensive collection of case studies that detail the outcomes of different game theoretic and bargaining strategies. Each case study is accompanied by an accessible and lucid explanation of the relevant theoretical aspects and is written with general readers and practitioners in mind. Game Theory will supplement the already existing literature and contributes to shaping the application of game theory appropriately in the actual practice of price negotiations. Scholars and students of economics will find the feedback from practitioners about the applicability and relevance of current research worthwhile reading. Furthermore, the text contains numerous valuable insights for those involved in negotiations, especially auctions, to help increase personal success."--
