Experimental economists have discovered various violations of expected utility theory and offered alternative models that can explain laboratory results. This study discovers a new violation in risky choices that cannot be explained by theories like Prospect Theory, Disappoint- ment or Regret...

This paper explores cultural differences in risky choices between Australian and German students. The focus is not on risk itself, but on tension which is a positive attribute of risky choices. Furthermore, the effects of real versus hypothetical payoffs are analysed. The experiment of this...

We analyze intraday trades of German stocks (Daimler Chrysler and SAP) that are traded simultaneously at the German stock market XETRA and the New York Stock Exchange (NYSE). At first glance, the stock price clustering seems to be less pronounced at the NYSE. But after converting Euro-prices...

Although the concept of utility is fundamental to many economic theories, up to now a generally accepted method determining a subject’s utility function is not available. We investigated two methods that are used in economic sciences for describing utility functions by using response-locked...

This study investigates context effects in general and the compromise effect in particular. It is argued that earlier research in this area lacks realism which is a major drawback to research conclusions and stated management implications. The importance of this issue is stressed by previous...

The St. Petersburg is one of the oldest violations of expected utility theory. Thus far, explanations of the paradox aim at small probabili- ties being perceived as zero and the boundedness of utility. This paper provides experimental results showing that neither risk attitudes nor perception of...

This paper focuses on the problem of probability weighing in the evaluation of lotteries. According to Prospect Theory a probability of 0.5 has a weight of smaller than 0.5. We conduct an EEG experiment in which we compare the results of the evaluation of binary lotteries by certainty...

This study focuses on the question whether it is risk aversion or the beliefs of players that explains the strategic choices in 2x2 coordination games. In a laboratory experiment, we elicit the risk attitudes by using lottery choices. Furthermore, using a quadratic scoring rule, subjects’...

Behavioral research revealed that product assortments can influence buyer preferences and affect purchase decisions between options of a product line. In this article, the compromise effect is investigated according to which the share of a product is expected to increase when it is in an...

This paper investigates decisions about inter-temporal tradeoffs. The objective of the study is to explore the valuation of time itself without tradeoffs between time and consequences. In an experimental study subjects made decisions about waiting time, where the time was subject to risk. We...
