This paper reports a field experiment involving manipulation of invitations to register in an experimental economics subject database. Two types of invitations were sent, one emphasizing pecuniary and the other non-pecuniary benefits of participation. It was found that first-year economicsmajors...

This study is a field experiment on loss aversion. The framing of scoring rules was differentiated in two exams at the University of Warsaw, with only half the students facing explicit penalty points in the case of giving an incorrect answer. Loss aversion predicts that less risk will be taken...

This study makes use of an unusual opportunity to manipulate framing of a simple decision under uncertainty: whether or not to answer an exam question when unsure which answer is correct and a missing response is scored higher than an incorrect one. Two treatments were compared in a natural...

This study measures hypothetical bias in CVM-based estimates of willingness to support a forest protection and restoration program in Poland. It does so in two parallel ways: within- and between-subjects. To this end, participants are asked to vote in a referendum on an NGO-led reforestation...

Several studies have identified the “better than average” effect – the tendency of most people to think they are better than most other people on most dimensions. The effect would have profound consequences, such as over-trading in financial markets. The findings are predominantly based on...

In this project we sought to contribute to extant literature on overconfidence by identifying it in a large, heterogeneous sample making familiar, repeated choices in a natural environment which provides direct feedback. In Study 1 we elicited predictions of own finishing time among participants...

In this study, we try to assess the prevalence of illicit downloading in the market of audio books and the willingness to admit to such practices. We compare the Bayesian Truth Serum (Prelec, 2004) treatment in which truthful responses and precise estimates are rewarded to the control treatment...

Ethical norms on the Internet are believed to be more permissive than in the ‘real’ world and this belief often serves as an explanation for the prevalence of the so-called digital “piracy”. In this study we provide evidence from a vignette experiment that contradicts this claim....

Attitudes towards uncertainty have been indicated to be highly context-dependent, and to be sensitive to the measurement technique employed. We present data collected in controlled experiments with 2939 subjects in 30 countries measuring uncertainty attitudes through incentivized measures as...
