This paper presents the design of an extended matchmaking component for electronic markets, which is able to identify negotiable agreements and the issues that are subject to the negotiation, in the case where basic matchmaking fails to find agreements that satisfy the constraints of the seller and the buyer. The foundation for this functionality is the introduction of negotiable constraints wi...

This paper analyzes the fundamental changes in market structures that may result from the increasing use of information technology. First, an analytic framework is presented and its usefulness is demonstrated in explaining several major historical changes in American business structures. Then, the framework is used to help explain how electronic markets and electronic hierarchies will allow clo...

As globalization moves forward, many IS/IT investments are being deployed across organizations located in different countries and world regions. Cross-system and inter-system integration and collaboration technologies play essential roles and often determine investment success or failure. However, economic, social and other factors outside the system must also be taken into consideration for gl...

In this study, we seek to further our knowledge of e-marketplaces by exploring empirically the existence of different types of business-to-business e-marketplaces. We used the reference model for electronic markets [Schmid & Lindemann 1998] as the theoretical foundation for a domain-specific model that we used to develop a set of coherent types of e-marketplaces, based on data from 24 German e-...

In the context of a virtual university’s information broker we study the consumption patterns for information goods and we investigate if Ehrenberg’s repeatbuying theory which successfully models regularities in a large number of consumer product markets can be applied in electronic markets for information goods too. First results indicate that Ehrenberg’s repeat-buying theory succeeds in descr...

Many electronic markets are linked together into larger “network markets” where the links reflect constraints on traders. These constraints mean that a choice to trade in one market limits the trader’s choice of other markets to use. This kind of network market is important because so many basic products, including gas, water, and electricity, are traded in such markets, and yet it has been lit...

Software agents help automate a variety of tasks including those involved in buying and selling products over the Internet. This paper surveys several of these agent-mediated electronic commerce systems by describing their roles in the context of a Consumer Buying Behavior (CBB) model. The CBB model we present augments traditional marketing models with concepts from Software Agents research to ...

My research studies the economic impact of IT-driven changes in the availability of market information. In particular, my dissertation examines the impact of Internet-enabled market transparency on consumer demand, firm strategy, and the broader impact on a market’s structure. My long term goal is to develop a modeling and empirical basis for a theory of market transparency in electronic market...

Reputation mechanisms have become an important component of electronic markets, helping to build trust and elicit cooperation among loosely connected and geographically dispersed economic agents. Understanding the impact of different reputation mechanism design parameters on the resulting market efficiency has, thus, emerged as a question of theoretical and practical interest. Along these lines...

Although E-Commerce has marketability as well as usefulness, there are few empirical studies on consumer acceptance using the transaction cost theory. This paper suggests that consumer product acceptance is determined by the difference of transaction cost. And the uncertainty and asset specificity which determine the transaction cost can affect the consumer acceptance of products. In addition, ...
