Keynote Speaker

Rudolf Vetschera
Full professor at the University of Vienna, studied economics and computer science at the University of Vienna and Technical University of Vienna. Research interests: Decision-oriented models of organizations, network organizations, multi-criteria decision making, decision support systems. He has been working in the field of MCDM area for about 15 years and came to Vienna in 1996 from the University of Konstanz, Germany. The main focus of teaching and research is on organization theory, but this area provides plenty of applications for multicriteria approaches

Plenary Session 1 – Response mode bias in decisions under risk
The response mode bias, in which subjects exhibit different risk
attitudes when assessing certainty equivalents versus indifference
probabilities is a well-known phenomenon in the assessment of utility functions. We present a set of experiments, in which we have studied the impact of problem characteristics on the measured risk attitudes. Our approach uses a new approximate measure of risk aversion. Our results indicate a strong impact of probability levels on the bias, different utility elicitation methods react differently to changed probability levels. This results in a particular pattern of biases, which we call the “tailwhip” effect. We have demonstrated this effect across a wide range of problems and subjects.

Plenary Session 2 – Analyzing e-negotiations from a quantitative and qualitative perspective
We give a broad overview of a set of studies on electronic negotiation processes. Our approach combines an analysis of the substantive issues of negotiations, in particular, offers, and the communication and relationship aspects. At both levels, we focus on the negotiation process, its influence factors, and the resulting outcomes of negotiations. By various examples of quantitative and qualitative studies, we show how the integration of different aspects can lead to a comprehensive understanding of negotiation processes.
