We present a novel approach to logic-based bilateral negotiation in ecommerce systems. We use Description Logics to describe both requests/offers submitted by buyers and sellers, and relations among issues as axioms in a TBox. Moreover, exploiting concept contraction in DLs, we are able to handle conflicting information both in goods and services descriptions. We ground the approach in a P2P e-...

Experimental studies of the WTP-WTA gap avoid social trading by implementing an incentive compatible mechanism for each individual trader. We compare a traditional random price mechanism and a novel elicitation mechanism preserving social trading, without sacrificing mutual incentive compatibility. Furthermore, we focus on risky goods— binary monetary lotteries—for which asymmetries in evaluati...

We describe a possible design strategy for a market specialist in the TAC Market Design Competition. Specifically, we describe both a linear charging policy that steadily increases the fees charged to trading agents interacting with the market, and an adaptive pricing policy that alters the trading price of goods based on the relative numbers of buyers and sellers in the market and the previous...

Automated negotiation offers new capability for buyers and sellers to efficiently trade goods and services in online markets. In high-dimensional real world negotiations, many agents may communicate with each other over multi-issue products. In this paper, we review soft-computing techniques used in e-negotiation. Although implementation of real world negotiations is very hard but using soft co...

The essential building block for Campbell’s policy recommendation is his assertion that bilateral bargaining between a single seller and a single buyer—as would occur after a merger to monopoly among the sellers that serve that buyer—induces efficient trade. He states: “The overall payment for all the goods will be subject to bargaining between the two parties, but the quantity sold is not in d...

Combined value auctions (CVAs) allow participants to make an offer of a single amount for a collection of items. These auctions provide value to both buyers and sellers of goods or services in a number of environments, but they have rarely been implemented, perhaps because of lack of knowledge and experience. Sears Logistics Services (SLS) is the first procurer of trucking services to use a CVA...

In hand, working in packed, precarious conditions, becoming sick due to COVID-19 will have devastating effects on sellers’ entire households. o...

Product bundles may consist of multiple units of a single product (" uniform " bundles) or multiple units of more than one product (" mixed " bundles). In this paper, we examine consumer evaluations of mixed and uniform bundles. Two factors can explain preferences for mixed bundles. First, consumers may perceive each additional unit of a particular product as possessing less marginal value. Sec...
