A vast literature shows that individuals frequently fail to identify the normative solutionsin logical reasoning tasks. Much attention has been devoted to the study ofthese deviations at the individual level; less effort was exerted to investigate whetherinstitutional settings might facilitate...

A great deal of late bidding has been observed on internet auctions such as ebay, which employ a second price auction with a fixed deadline. Much less late bidding has been observed on internet auctions such as those run by Amazon, which employ similar auction rules, but use an ending rule that...

Spieltheoretische Überlegungen zeigen, dass Reputationsmechanismen, wie sie auf Internet-Marktplattformen zur Anwendung kommen, prinzipiell geignet sind, Handel in großen anonymen Märkten zu erleichtern. Dies geil selbst dann, wenn die Marktteilnehmer ihre Identität jederzeit und kostenlos...

This paper studies how software agents influence the market behavior ofhuman traders. Programmed traders with a passive arbitrage seekingstrategy are introduced in a double auction market experiment with humansubjects in the laboratory. As a treatment variable, the influence ofinformation on the...

Are commonly known beliefs essential for bidding behavior in asymmetric auctions? Our experimental results suggest that not informing participants how values are randomly generated does not change behavior much and may even make it appear more rational.

Many bidders in eBay employ bidding strategies that involve late bids, incremental bids, or both. Based on field evidence, we discuss teh manner in which late bids are caused both by sophisticated, strategic reasoning and by irrationality and inexperience, the interaction of late bidding and...

Auctions on the Internet provide a new source of data on how bidding is influenced by the detailed rules of the auction. Here we study the second-price auction run by eBay and Amazon, in which a bidder submits a reservation price, and has this (maximum) price used to bid for him by proxy.[...]

Experimental sealed bid first price auctions with private values in which feedback onthe losing bids is provided yield lower revenues than auctions where this feedback isnot given. Furthermore, bids tend to be above the equilibrium predictions for riskneutral bidders. While the latter...

The internet facilitates interactive and asynchronous communication among human and artificial agents in large bilateral markets. As a consequence, new institutional structures are emerging in the new economy. I discuss a few core problems associated with the economic design of internet markets...

Least-Unmatched Price Auctions have become a popular format of TV and radio shows. Increasingly,they are also applied in internet trading. In these auctions the lowest single (unique)bid wins. We analyze the game-theoretic solution of least unmatched price auctions when prize,bidding cost and...
