Double auctions are widely used market mechanisms on the world. Communication technologies such as internet increased importance of this market institution. The purpose of this study is to develop novel bidding strategies for dynamic double auction markets, explain price formation through interactions of buyers and sellers in decentralized fashion and compare macro market outputs of different micro bidding strategies.

In this study, two novel bidding strategies based on fuzzy logic are presented. Also, four new bidding strategies based on price targeting are introduced for the aim of comparison. The proposed bidding strategies are based on agent-based computational economics approach. The authors performed multi-agent simulations of double auction market for each suggested bidding strategy. For the aim of comparison, the zero intelligence strategy is also used in the simulation study. Various market outputs are obtained from these simulations. These outputs are market efficiencies, price means, price standard deviations, profits of sellers and buyers, transaction quantities, profit dispersions and Smith’s alpha statistics. All outputs are also compared to each other using t-tests and kernel density plots.

The results show that fuzzy logic-based bidding strategies are superior to price targeting strategies and the zero intelligence strategy. The authors also find that only small number of inputs such as the best bid, the best ask, reference price and trader valuations are sufficient to take right action and to attain higher efficiency in a fuzzy logic-based bidding strategy.

This paper presents novel bidding strategies for dynamic double auction markets. New bidding strategies based on fuzzy logic inference systems are developed, and their superior performances are shown. These strategies can be easily used in market-based control and automated bidding systems.

Voyager Inn International (Bethesda) is negotiating a master contract with TourAmerica, an international tour operator, for hotel rooms during the 1995 tourist season. Issues under consideration include number of rooms during peak, mid-, and off-periods; room rates; breakfast prices; and the cost of ancillary services. The hotel manager is evaluated on the basis of several criteria, including adjusted daily rates, occupancy rates, and food and beverage profitability. To facilitate trade-offs among the various criteria, the manager articulates a utility scheme. This case is a role-play exercise, and must be used in conjunction with “TourAmerica” (UVA-QA-0464). Reporting forms for the evaluation of alternative contracts are provided with each case.

This case considers the unusual terms under which Rhone-Poulenc, the large French chemicals producer, acquired the U.S.-based Rorer Group, Inc., in August 1990. Set a year later, in August 1991, the case reviews the terms of the merger and the experience of the new entity in its first year, and invites the student to evaluate the “contingent value right” (CVR) issued by Rhone-Poulenc in the merger.

This paper presents an e‐commerce system that is being used for construction material procurement. The paper identifies the limitations relating to information retrieving, recording and sharing in the traditional material procurement process. E‐commerce applications that can improve the efficiency and effectiveness of the material procurement process in construction are then identified and described. Finally, the design and implementation of an e‐commerce system for construction material procurement for trading construction materials in China is presented and discussed.
