Bidding in the last seconds or minutes of an auction is a common strategy in Internet auctions with fixed end-time. This paper examines the three explanations of late bidding in eBay auctions that survived the first scrutiny in Roth and Ockenfels (2002). There is no indication that late bidding could lead to collusive gains for bidders. Late bidding is a strategic response to the presence of bidders placing multiple bids. Experts protecting their private information are typically the last to bid, while collectors are often the first. As bidders gain familiarity with eBay rules, they tend to bid slightly earlier.

There is a great deal of late bidding on internet second price auctions. We show that this need not result from either common value properties of the objects being sold, or irrational behavior: late bidding can occur at equilibrium even in private value auctions. The reason is that very late bids have a positive probability of not being successfully submitted, and this opens a way for bidders to implicitly collude, and avoid bidding wars, in auctions such as those run by eBay, which have a fixed end time. A natural experiment is available because the auctions on Amazon, while operating under otherwise similar rules, do not have a fixed end time, but continue if necessary past the scheduled end time until ten minutes have passed without a bid. The strategic differences in the auction rules are reflected in the auction data by significantly more late bidding on eBay than on Amazon. Futhermore, more experienced bidders on eBay submit late bids more often than do less experienced bidders, while the effect of experience on Amazon goes in the opposite direction. On eBay, there is also more late bidding for antiques than for computers. We also find scale independence in the distribution over time of bidders' last bids, of a form strikingly similar to the deadline effect' noted in bargaining: last bids are distributed according to a power law. The evidence suggests that multiple causes contribute to late bidding, with strategic issues related to the rules about ending the auction playing an important role

Document from the year 2010 in the subject Business economics - General, grade: 8,0, Maastricht University, language: English, abstract: The following short paper underlines the impact of bidding behaviour, at eBay auctions, on the sales price. At the online auction portal eBay, bidders try to get the object of desire as cheap as possible with the highest evidence of quality and security, while sellers try to sell their product for the highest price possible. This paper elaborates on the impacts of minimum pricing, reserve prices, last minute bidding, sniping and seller’s reputation on the end prices of eBay auctions from seller’s and buyer’s perspective.

This paper shows that in online auctions like eBay, if bidders can only place bids at random times, then many di fferent equilibria arise besides truthful bidding, despite the option to leave proxy bids. These equilibria can involve gradual bidding, periods of inactivity, and waiting to start bidding towards the end of the auction - bidding behaviors common on eBay. Bidders in such equilibria implicitly collude to keep the increase of the winning price slow over the duration of the auction. In a common value environment, we characterize a class of equilibria that include the one in which bidding at any price is maximally delayed, and all bids minimally increment the price. The seller's revenue can be a small fraction of what could be obtained at a sealed-bid second-price auction, and in the worst equilibrium it is decreasing in the value of the object. With many bidders, we show that this equilibrium has the feature that bidders are passive until near the end of the auction, and then they start bidding incrementally.

Despite the recent misfortunes of many dotcoms, e-commerce will have major and lasting effects on economic activity. But the rise and fall in the valuations of the first wave of e-commerce companies show that vague promises of distant profits are insufficient. Only business models based on sound economic propositions will survive. This book provides professionals, investors, and MBA students the tools they need to evaluate the wide range of actual and potential e-commerce businesses at the microeconomic level. It demonstrates how these tools can be used to assess a variety of existing applications. Advances in web-based technology--particularly automation and delegation technologies such as smart agents, shopping bots, and bidding elves--support the further growth of e-commerce. In addition to enabling consumers to conduct automated comparisons and sellers to access visitors' background information in real time, such software programs can make decisions for individuals, negotiate with other programs, and participate in online markets. Much of e-commerce's economic value arises from this kind of automation, which not only reduces operating costs but adds value by generating new market interactions. This text teaches how to analyze the added value of such applications, considering consumer behavior, pricing strategies, incentives, and other critical factors. It discusses added value in several e-commerce arenas: online shopping, business-to-business e-commerce, application design, online negotiation (one-to-one trading), online auctions (one-to-many trading), and many-to-many electronic exchanges. Combining insights from several years of microeconomic research as well as from game theory and computer science, it stresses the importance of economic engineering in application design as well as the need for business models to take into account the "total game." As the only serious treatment of the microeconomics of e-commerce, this book should be read by anyone seeking e-commerce solutions or planning to work in the field.

Economists often look at markets as given, and try to make predictions about who will do what and what will happen in these markets. Market design, by contrast, does not take markets as given; instead, it combines insights from economic and game theory together with common sense and lessons learned from empirical work and experimental analysis to aid in the design and implementation of actual markets In recent years the field has grown dramatically, partially because of the successful wave of spectrum auctions in the US and in Europe, which have been designed by a number of prominent economists, and partially because of the increase use of the Internet as the platform over which markets are designed and run There is now a large number of applications and a growing theoretical literature. The Handbook of Market Design brings together the latest research from leading experts to provide a comprehensive description of applied market design over the last two decades In particular, it surveys matching markets: environments where there is a need to match large two-sided populations to one another, such as medical residents and hospitals, law clerks and judges, or patients and kidney donors It also examines a number of applications related to electronic markets, e-commerce, and the effect of the Internet on competition between exchanges.

This book provides a new bidding strategy for agents to adopt in continuous double auctions (CDAs) and proposes some generally used tools to enhance the performance of existing bidding strategies in CDAs. It is the first book to focus on CDAs where a limited amount of seller agents and buyer agents trade what they want. The superior performance of the new bidding strategy and the tools proposed by this book are illustrated through extensive experiments.
