First-price auctions, Dutch auctions, and buy-it-now-prices with Allais paradox bidders
This paper investigates first-price and Dutch auctions when bidders have preferences exhibiting the Allais paradox. We characterize an equilibrium for both auctions, paying particular attention to the dynamic inconsistency problems which can arise with such preferences. We show that the Dutch auction systematically yields a higher revenue than the first-price auction. This stands in sharp contrast with the presumption that these auctions are strategically equivalent, which is indeed valid in the expected utility case. We also show that introducing a "buy-it-now-price" to the first-price auction increases seller's expected revenue when bidders have Allais paradox preference while it does not for expected-utility maximizers.Dutch auctions (descending auctions), Allais paradox, buy-it-now-prices
The Biggest Auction Ever: the Sale of the British 3G Telecom Licenses
This paper reviews the part played by economists in organizing the British third-generation mobile-phone licence auction that concluded on 27 April 2000. It raised £22 1/2 billion ($34 billion or 2 1/2% of GNP) and was widely described at the time as the biggest auction ever. We discuss the merits of auctions versus "beauty contests", the aims of the auction, the problems we faced, the auction designs we considered, and the mistakes that were made.Auctions, Telecommunications, Spectrum Auctions, Mobile Phones, 3G, UMTS, Bidding.
A typology of foreign auction markets in sub-Saharan Africa
The authors compare and contrast the design and outcomes of different foreign exchange auctions in four countries in sub-Saharan Africa and present a typology of such auctions. They identify two distinct sets of countries in terms of the auctions'features, policy interventions, and outcomes. In Ghana and Uganda, the exchange rate auctions are judged to have been largely on target in exchange rate unification, exchange rate stabilization,and efficient allocation of foreign exchange. The auctions in Nigeria and Zambia, on the other hand, were subject to frequent policy interventions, resulting in unsustainable auctions, inefficient allocation of foreign exchange (through ad hoc disqualifications), limited unification, and a rather volatile exchange rate. The conclusions reached by the authors are broadly corroborated by a statistical analysis of weekly micro-auction data for all four countries.Economic Theory&Research,Markets and Market Access,Access to Markets,International Terrorism&Counterterrorism,Economic Stabilization
Internet Auctions: Description, Bidders' Profiles and Implications
The increasing quantity of items bough and sold over the internet led to the success of internet auctions, to the introduction of new auction rules and the creation of new businesses and merger among existing ones. In this paper, we present a description of existing internet auction rules and typical profile of consumers who use them. We found that bidders are most likely located in the U.S., have some internet experience and skills and that they belong to the 26-50 years old age group. We also discuss the implication of online auctions on resource allocation.Internet Auctions, Online Auctions
Online Auctions
The economic literature on online auctions is rapidly growing because of the enormous amount of freely available field data. Moreover, numerous innovations in auction-design features on platforms such as eBay have created excellent research opportunities. In this article, we survey the theoretical, empirical, and experimental research on bidder strategies (including the timing of bids and winner's-curse effects) and seller strategies (including reserve-price policies and the use of buy-now options) in online auctions, as well as some of the literature dealing with online-auction design (including stopping rules and multi-object pricing rules).
The Dutch DCS-1800 Auction
In February 1998 the Dutch government auctioned licences to operate mobile telecommunications networks according to the DCS-1800 technology. Two “national” licences and sixteen “regional” ones were auctioned by using a variant of the simultaneous, multiple round auction that was proposed by US-economists and that had been tested in the US. This paper describes how the decision to auction came about, it details the auction rules, and it analyzes the resulting outcomes.Telecommunications;Auctions;Regulation
A Rule-driven Approach for Defining the Behavior of Negotiating Software Agents
One problem with existing agent-mediated negotiation systems is that they rely on ad hoc, static, non-adaptive, and hardcoded schemes to represent the behaviour of agents. This limitation is probably due to the complexity of the negotiation task itself. Indeed, while negotiating, software (human) agents face tough decisions. These decisions are based not only on the information made available by the negotiation server, but on the behaviour of the other participants in the negotiation process as well. The information and the behaviour in question are constantly changing and highly uncertain. In the first part of the paper, we propose a rule-driven approach to represent, manage and explore negotiation strategies and coordination information. For that, we divide the behaviour of negotiating agents into protocols, strategies and coordination. Among the many advantages of the proposed solution, we can cite the high level of abstraction, the closeness to human understanding, the versatility, and the possibility to modify the agents' behaviour during the negotiation process. To validate our solution, we ran many agent tournaments, and used the rule-driven approach to implement bidding strategies that are common in the English and Dutch auctions. We also implemented simple coordination schemes across several auctions. The ongoing validation work is detailed and discussed in the second part of the paper. Un des inconvénients qu'on retrouve fréquemment dans les systèmes de négociation par agents est qu'ils reposent sur des schémas ad-hoc, non adaptatifs et figés dans le code pour représenter le comportement des agents. Cette limitation est probablement due à la complexité de l'activité de négociation elle-même. En effet, au cours de la négociation, les agents logiciels (humains) ont des décisions difficiles à prendre. Ces décisions ne sont pas seulement basées sur l'information disponible sur le serveur de négociation, mais aussi sur le comportement des autres participants durant le processus de négociation. L'information et le comportement en question changent constamment et sont très incertains. Dans la première partie de l'article, nous proposons une approche à base de règles pour représenter, gérer et explorer les stratégies de négociation ainsi que l'information de coordination. Parmi les nombreux avantages de la solution proposée, on peut citer le haut niveau d'abstraction, la proximité avec la compréhension humaine, la souplesse d'utilisation et la possibilité de modifier le comportement des agents durant le processus de négociation. Pour valider notre solution, nous avons effectué plusieurs tournois entre agents et utilisé l'approche à base de règles pour implémenter des stratégies simples applicables à l'enchère anglaise et à l'enchère hollandaise. Nous avons aussi implémenté des schémas simples de coordination impliquant plusieurs enchères. Le travail de validation, en cours, est détaillé et discuté dans la seconde partie de l'article.e-negotiation, online auction, software agent, negotiation strategy, coordination, rule-based system, rule engine, Négociation électronique, enchères en ligne, agents logiciels, stratégie de négociation, coordination, système à base de règles, moteur de règles
