Information Architecture and Electronic Market Performance

Electronic markets are one of the most prominent business applications of the Internet, so determining the factors that drive their performance is of great value. This thesis shows that an important driver of electronic market performance is the information architecture of the market, which describes what type of information is available to whom during the market process. Two studies of electronic market initiatives at a large Dutch flower auction highlight how information and communication technology (ICT) affects the information architecture of the market and the consequences for market behavior. ICT not only affects existing markets, but also offers opportunities to design innovative new market mechanisms. One of these is a multidimensional auction, in which bidders bid not only on price, but also on dimensions such as quality and delivery time. The effects of different information architectures of multidimensional auctions are explored in laboratory experiments. The findings of the three studies are synthesized into a theory of electronic markets that has important implications for market designers, traders and researchers.

Otto Koppius studied Applied Mathematics at the University of Twente in the Netherlands, with a major in graph theory. During his studies, he spent several months at the University of South Australia, working on a project involving the optimal layout of mineshafts. In June 1997, he received his M.Sc. degree for a thesis on the novel graph-theoretic problem of finding degree-preserving spanning trees, which arose from an application in water distribution networks. In September 1997, he took up a position as Ph.D. student at the department of Decision and Information Sciences at the Rotterdam School of Management, Erasmus University. In 1998, he was one of the recipients of a grant from the Carnegie Bosch Institute at Carnegie-Mellon University, for a project on electronic sourcing strategy. The same year, his dissertation proposal on electronic multidimensional auctions was runner-up in the contest for "Best E-Commerce Thesis Proposal", organized by IBM Research's Institute for Advanced Commerce. The following year, he spent three months as a visiting researcher at the University of Michigan, as well as three months at the IBM T.J. Watson Research Center. He was invited to the doctoral consortia of the International Conference on Information Systems in 1999 and the Academy of Management in 2000 and he has presented his work at various other conferences, including INFORMS, the Workshop on Information Systems and Economics, the Hawaii International Conference on Systems Sciences, the European Conference on Information Systems, the Sunbelt Social Network Analysis conference and the Strategic Management Society. He is currently an assistant professor at the department of Decision and Information Sciences at the Rotterdam School of Management, Erasmus University. As a result of his research on electronic markets, his research interests branch out into areas within strategic management, entrepreneurship, behavioral decision theory and social network analysis.
