Online auction has become an intriguing new type of economic exchange mechanism. Given that Internet auctions differ from traditional physical auctions in terms of flexibility and synchronicity, there is much doubt as to whether existing theoretical and empirical literature on traditional physical auctions still holds. This paper seeks to unravel factors affecting Internet auction prices. Speci...

We address the fundamental issue of revenue and efficiency in the combinatorial and simultaneous auction using a novel approach. Specifically, upper and lower bounds are constructed for the first-price sealed-bid setting of these two auctions. The question of revenue is important yet very few results can be found in the literature. Only for very small instances with 2 items have comparisons bee...

We consider a setting where there is a manufacturer who wants to procure multiple items from a set of suppliers each of whom can supply one or more of these items (bundles). We design an ascending price auction for such a setting which implements the Vickrey-Clarke-Groves outcome and truthful bidding is an ex post Nash equilibrium. Our auction maintains non-linear and non-anonymous prices throu...

This paper continues the study, initiated by Cole and Fleischer in [Cole and Fleischer 2008], of the behavior of a tatonnement price update rule in Ongoing Fisher Markets. The prior work showed fast convergence toward an equilibrium when the goods satisfied the weak gross substitutes property and had bounded demand and income elasticities. The current work shows that fast convergence also occur...

Inspired by the recent developments in the field of Spectrum Auctions, we have tried to provide a comprehensive framework for the complete procedure of Spectrum Licensing. We have identified the various issues the Governments need to decide upon while designing the licensing procedure and what are the various options available in each issue. We also provide an in depth study of how each of this...

In mass customization, companies strive to enhance customer value by providing products and services that are approximate to customers’ needs. A company’s strategy of allocating its limited capacity to meeting diverse customer requirements directly impact customer perceived value in terms of available options, cost, and schedule. Proposed in this paper is an auction-based mass customization mod...

We analyze the realistic, popular format of an ascending auction with anonymous itemprices, when there are two items that are substitutes. This auction format entails increased opportunities for bidders to coordinate bids, as the bidding process is longer, and since bidders see the other bids and can respond to various signaling. This has happened in many real auctions, e.g., in the Netherlands...

eBay is by far the world’s largest online auction site. Millions of people are doing transactions through it. eBay offers the sellers several additional listing options (“ALO” for short) at certain prices for them to enhance the visibility or attractiveness of their auction listings. In this paper we tried to find out how much these ALO can help to improve the outcome of an online auction, focu...

In spring 2000, the British government auctioned off licences for Third Generation mobile telecommunications services. In the preparation of the auction, two designs involving each a hybrid of an English and a sealed-bid auction were suggested by the government: a discriminatory and a uniform price variant. We report an experiment on these two designs, and also compare the results to those with...
