It has been shown that subjects tend to follow others' behavior even when the external signals are uninformative. In this paper we go one step further, showing that conformism occurs even when the choices of others are not even presented to the subjects, but just indirectly perceived. We use the...

This paper presents a nonparametric approach to classification of data from lottery experiments. Using very basic mathematical tools the paper endeavors to answer the questions: How to determine the “average” subject in a group? How to find a subject presenting the most similar behavior to a...

This short paper demonstrates that the claim of Cumulative Prospect Theory (CPT) that people are risk seeking for loss prospects, which confirmed a hypothetical assumption of the earlier Prospect Theory (PT), appears to be merely a result of using a specific form of the probability weighting...

In the real life groups, rather than individuals, take the most part of decisions. So that it is useful to study how groups take a decision in different strategic environments. This paper provides an overview of previous research about groups’ preferences over risk. I compare different...

Individuals vary in their willingness to take financial risks. Here we show that variants of two genes that regulate dopamine and serotonin neurotransmission and have been previously linked to emotional behavior, anxiety and addiction (5-HTTLPR and DRD4) are significant determinants of risk...

We explore the individual and joint explanatory power of concepts from economics, psychology, and criminology for criminal behavior. More precisely, we consider risk and time preferences, personality traits from psychology (Big Five and locus of control), and a self-control scale from...

We study higher-order risk preferences, i.e. prudence and temperance, next to risk aversion in social settings. Previous experimental studies have shown that higher-order risk preferences affect the choices of individuals deciding privately on lotteries that only affect their own pay-off. Yet,...
