auctions have been as a competitive method of buying and selling valuable or rare items for a long time. single-sided auctions in which participants negotiate on a single attribute (e.g. price) are very popular. double auctions and negotiation on multiple attributes create more advantages compared to single-sided and single-attribute auctions. nonetheless, this adds the complexity of the auctio...

This article discusses the auction phenomenon in buying and selling transactions: a study of syarah hadith. research is important because lack literature on hadith about auctions. The purpose this to discuss method used by using qualitative research. results include auctions, concept conclusion difference opinion scholars regarding auctions transactions.

We study a family of convex polytopes, called SIM-bodies, which were introduced by Giannakopoulos and Koutsoupias in 2018 to analyze so-called Straight-Jacket Auctions. First, we show that the SIM-bodies belong class generalized permutahedra. Second, prove an optimality result for Auctions among certain deterministic auctions. Third, employ computer algebra methods mathematical software explici...

This special issue of EM — Electronic Markets on ‘Innovative Auction Markets’ illustrates the increasingly pervasive and diverse applications of online auctions. From auctions for keywords tied to search engines, to B2B and financial auctions, or the use of auctions to generate predictive information for decision making — online auctions are becoming more widely applied in practice. Since the l...

Spectrum is a valuable, scarce and finite natural resource that is needed for many different applications, so efficient use of the scarce radio spectrum is important for accommodating the rapid growth of wireless communications. Spectrum auctions are one of the best-known market-based solutions to improve the efficiency of spectrum use. However, Spectrum auctions are fundamentally differen...

Internet auctions for consumers’ goods are an increasingly popular selling venue. We have observed that many sellers, instead of offering their entire inventory in a single auction, split it into sequential auctions of smaller lots, thereby reducing the negative market impact of larger lots. Information technology also makes it possible to collect and analyze detailed bid data from online aucti...

We study independent private value auctions where bidders have preferences over relative payoos. We derive symmetric equilibria for four important auction forms: rst-price, second-price, English, and Dutch. We nd that equilibrium bidding is more aggressive than standard predictions. Indeed, in second-price auctions it is optimal to bid above one's valuation when bidders care about relative payo...

Auctions have emerged as the primary means of assigning spectrum licenses to companies wishing to provide wireless communication services. Since July 1994, the Federal Communications Commission (FCC) has conducted 33 spectrum auctions, assigning thousands of licenses to hundreds of firms. Countries throughout the world are conducting similar auctions. I review the current state of spectrum auct...

We study multi-object auctions where agents have private and additive valuations for heterogeneous objects. We focus on the revenue properties of a class of dominant strategy mechanisms where a weight is assigned to each partition of objects. The weights influence the probability with which partitions are chosen in the mechanism. This class contains efficient auctions, pure bundling auctions, m...
