The efects of trading institutions on market eficiency and trading volume are examined. The trading institutions are computerized versions of continuous double auction and "clearinghouse" markets. Traders are experienced, profit-motivated undergraduates. The traded good is afinancial asset whose moneta y value is stateand trader type-contingent. Traders possess asymmetric private information on...

To build a new bidding model of multi-attribute online auctions, this paper introduces the concepts of multi-type attribute and nonlinear function. The model can measure the effect of the attributes in auctions by adopting the normalized method of weighting and it will set the stage for the purchasers to evaluate suppliers in the procurement management. Furthermore, this paper developed an appl...

To be successful in multi-attribute auction, agents must be capable of adapting to continuous changing bidding price. This paper presents a novel fuzzy attitude based bidding strategy (FA-Bid), which employs dual assessment technique i.e. assessment of multiple attributes of the goods as well as assessment of agents attitude (eagerness) to procure an item in automated auction. The assessment of...

Multi Attributes Procurement Auction is a well known solution for negotiation between sellers and buyers. Seller wants to sell the product with more prices while buyer wants to buy the product with fewer prices. This problem has been analyzed by game theory approach and one optimal solution is achieved for the seller and the buyer with this assumption that the seller knows the exact value of th...

The use of e-Auction services has been increasing in recent years. Security requirements in conducting eAuctions are mainly bid privacy, anonymity and public verifiability. Most of the secure protocols concentrate on privacy and anonymity, which are achieved through bidder-resolved multi-party computation, assuming two or more trusted third parties, either through numerous auctioneers or with a...

Auction models are found efficient in managing resources allocation, which is a key technology in grid computing system. In this paper, a new reverse auction approach is proposed, and its mechanism and related auction algorithm are designed. In our approach, the grid trading service, i.e., an intelligent entity, uses this auction algorithm to estimate the resource user’s satisfaction degree and...

The vast majority of electronic markets have been based purely on a single variable (price) as the factor that determines ‘the winner’. Multi-attribute auctions are likely to be more appropriate for procurement scenarios where factors other than price need to be considered in determining the outcome. Nevertheless, there is a scarcity of empirical research on multi-attribute electronic auctions....
