Sous quelles conditions se réalise l'ajustement entre l'offre et la demande lorsque le marché bouleverse le jeu des intermédiaires qui s'y consacrent? L'article étudie les dispositifs mis en place sur Internet par la plate-forme d'intermédiation eBay; il met en évidence la centralité du processus de qualification qui définit l'objet matériel, ses parties prenantes et les conditions de l'échange. Il s'articule dans un dispositif sophistiqué et complexe qui permet à la fois au jeu de l'offre et de la demande de (...) s'exercer et à l'intermédiaire de s'abstraire de la transaction.Under what conditions is carried adjustment between supply and demand when the market upsets the game intermediaries engaged in it?

The Delaware court's decision in eBay v. Newmark has been viewed by many commentators as a decisive affirmation of shareholder wealth maximization as the only legally permissible objective of a for-profit corporation. The implications of this court case are of particular concern for the emerging field of social enterprise, in which some organizations, such as, in this case, Craigslist, choose to pursue a social benefit mission in the for-profit corporate form. The eBay v. Newmark decision may also threaten (...) companies that seek to be socially responsible by serving constituencies other than shareholders at the expense of some profit. This examination of the court decision concludes that a legal requirement to maximize shareholder value may not preclude a commitment to social responsibility and may even permit the pursuit of a social benefit objective, such as the preservation of the culture developed by Craigslist. In particular, the court's decision in eBay v. Newmark reflects unique features of the case that could have been avoided by Craigslist and by other similar companies. (shrink)

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 marketisation of heritage has been a major topic of interest among heritage specialists studying how the online marketplace shapes sales. Missing from that debate is a large-scale analysis seeking to understand market trends on popular selling platforms such as eBay. Sites such as eBay can inform what heritage items are of interest to the wider public, and thus what is potentially of greater cultural value, while also demonstrating monetary value trends. To better understand the sale of heritage (...) on eBay’s international site, this work applies named entity recognition using conditional random fields, a method within natural language processing, and word dictionaries that inform on market trends. The methods demonstrate how Western markets, particularly the US and UK, have dominated sales for different cultures. Roman, Egyptian, Viking and Near East objects are sold the most. Surprisingly, Cyprus and Egypt, two countries with relatively strict prohibition against the sale of heritage items, make the top 10 selling countries on eBay. Objects such as jewellery, statues and figurines, and religious items sell in relatively greater numbers, while masks and vessels sell at generally higher prices. Metal, stone and terracotta are commonly sold materials. More rare materials, such as those made of ivory, papyrus or wood, have relatively higher prices. Few sellers dominate the market, where in some months 40% of sales are controlled by the top 10 sellers. The tool used for the study is freely provided, demonstrating benefits in an automated approach to understanding sale trends. (shrink)

Applying an evolutionary framework, we investigate how a reputation mechanism and a buyer insurance (as used on Internet market platforms such as eBay) interact to promote trustworthiness and trust in markets with moral hazard problems. Our analysis suggests that the costs involved in giving reliable feedback determine the gains from trade that can be obtained in equilibrium. Buyer insurance, on the other hand, can affect the trading dynamics and equilibrium selection. We find that, under reasonable conditions, buyer insurance crowds (...) out trust, and trustworthiness.

This article examines the relationship between online dispute resolution (ODR) and trust. We discuss what trust is, why trust is important, and how trust develops. Our claim is that efforts to implement online dispute resolution on a site or service in a manner that promotes trust need to consider ODR as just one tool in a broader toolbox of trust-building tools and techniques. These techniques are amongst others marketing, education, trust seals, and transparency. By evaluating ODR in its proper context (...) as one component of a larger trust strategy, we can more accurately set expectations for its results and position our projects for success. (shrink)

Internet fraud is an issue that increasingly concerns regulators, consumers, firms, and business ethics researchers. In this article, we examine one common form of internet fraud, the practice of shill bidding (when a seller in an auction enters a bid on his or her own item). The significant incidence of shill bidding on eBay (in spite of the fact that it is illegal just as it is in live auctions) exemplifies the current ineffectiveness of regulatory means as well as (...) the lack of effective societal mechanisms to prevent online fraud. Further, the proliferation of shill bidding along with other types of internet fraud may have broader implications. If unethical behavior such as shill bidding becomes too widespread on the internet, regulators and other societal forces may deem it necessary to institute controls that will impact the entire online marketplace as well as the future development and regulation of business activities on the internet. Our results indicate that shill bidding is perpetrated on eBay significantly more often than 0.1% rate of fraud estimated by the firm. This suggests that regulators, users, and others stakeholders may become concerned enough to act. The impact of those responses on the internet of the future may affect a broad array of users beyond the unethical sellers on eBay. (shrink)

This chapter discusses the following three fundamental features of our online environment: epistemic success, connectivity, and coordination. The Internet connects people and makes communication, interaction, and transactions between them easy and cheap. Two‐sided markets and platforms, like Uber, Airbnb and eBay, allow buyers and sellers, demand and supply, to find each other, and to coordinate their behavior and engage in interactions, transactions, and collaboration. In addition to these features, a number of other features of our online environments shed light (...) on how evil online gets traction. Many of these features – notably, selectivity, anonymity, positionality, domestication, isolation, conflation of public/ private contrasts, high voluntariness, jurisdiction, virtuality, and interpretive flexibility – have enabled the doing and consumption of evil in a particular way. They have created and magnified moral fog in the minds of users. (shrink)

Star Wars action figures can help illuminate some theories about the science of the mind and how religious thinking originated. Playing with action figures illustrates how a science of the mind is possible and what can go wrong in the religious mind. In the twentieth century, philosophers began to think of new ways to study the mind. The key is to switch from a first‐person view to a third‐person perspective. Playing with Star Wars action figures illustrates Daniel Dennett's theory of (...) how a science of the mind is possible. To illustrate, this chapter presents a vintage Blue Snaggletooth action figure that sells for hundreds of dollars on eBay. The chapter highlights that understanding what happens when we play with action figures can reveal how a science of mind is possible and illuminate a theory of the origins of the religious mind.

In today’s competitive environments, a growing number of firms are establishing their presence through the Web sites. Based on Steuer’s and Rheingold’s arguments on perceptual experience in the virtual space, this paper provides a theoretical framework that highlights the effects of interactivity, immersion, and association for customers. The paper argues that though interactivity, immersion, and association are critical for attracting customers on a Web site, these characteristics may also lead to social, ethical and privacy concerns among customers that many unscrupulous (...) firms tend to exploit for their advantages. Interactivity has been measured through speed, range, and significance of interactivity. Immersion has been measured through breadth and depth of immersion. Association has been categorized into one‐to‐one or many‐to‐many relationships. Four Web sites, amazon.com, eBay.com, schwab.com, and victoriasecret.com, are analyzed with respect to interactivity, immersion, and association. The implications of the use and abuse of interactivity, immersion, and association are discussed. (shrink)

The main results of our indirect evolutionary approach to trust in large interactions suggest that trustworthiness must be detectable if good conduct in trust-relationships is to survive. According to theoretical reasoning there is a niche then for an organization offering a (possibly) costly service of keeping track of the conduct of participants on the net. We compare traits of an organizational design as suggested by economic reasoning with those that actually emerged and ask whether institutions like eBay will increasingly (...) have to ‘economize on virtue’ although so far they could rely on its spontaneous provision.

Spirited disagreement exists among online auction participants over the ethics of sniping: delaying one's bid until the closing seconds of an online auction. Through analysis of the structural features of online auctions and by deploying Rawls's (1955) distinction between justifying an action under a practice and justifying the practice itself, I argue that: (i) the disagreement is better conceived as one over the ethics of online auction hosting (and therefore, over business ethics) than over the ethics of online auction participation; (...) (ii) so conceived, the argument against sniping is nonetheless implausible; and (iii) the disagreement remains interesting not on the merits, but for the curious fact that it is bidders who complain about sniping.
