Working Papers

The WNE Working Papers series has been published by the Faculty of Economic Sciences at the University of Warsaw since 2008.

The WNE Working Papers series provides a fast, open channel for disseminating research conducted at the Faculty of Economic Sciences, University of Warsaw. The papers hosted here are working versions (pre-prints) and may evolve as authors refine their analyses, incorporate feedback, or progress through formal peer-review. What you read is the current version released by the authors, timestamped and assigned DOI/ISSN identifiers to ensure precise citation and version tracking. Copyright remains with the authors, who may, at any time, upload a revised file or add a note directing readers to a later, peer-reviewed publication.

The Working Papers series accepts articles by research employees of the Faculty and publications from conferences organised at the Faculty of Economic Sciences at the University of Warsaw. Articles should be original research papers which have not been previously published, on the subject of economics.

WP75. Sex, morals and exam cheating

This paper reports a field experiment investigating effectiveness of moral appeal in discouraging exam cheating. Substantial level of cheating was identified using an index of test answers similarity, contrasted with low self-reports. The treatment manipulation made an impact on self-reported but not observed frequency of cheating. Hypothesized gender difference, whereby males took but not gave more illicit information than females was also found.

WP54. Framing in the field. A simple experiment on the reflection effect

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 field experiment: one in which the decision was framed in terms of losses, and the other - in terms of gains. Some alternative theories of decision making under risk, notably prospect theory, propose that individuals display reflection effect, i.e. tend to be more risk-seeking in losses than gains. No such evidence was found: subjects were generally risk-averse and this disposition was not affected by treatment.

WP53. To answer or not to answer? A field test of loss aversion

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 (less questions will be answered) when losses are possible but in fact, no treatment effect was observed.
