“…Because of the many negative effects of corruption on society, 1 there is a lot of interest in the study of factors influencing corrupt behavior and examining effects of various anticorruption policies, oftentimes in laboratory settings. Although some of the explored approaches are less typical, such as staff-rotation (Ryvkin & Serra, 2012), competition among public officials (Shleifer & Vishny, 1993), anonymous public reporting (Ryvkin, Serra, & Tremewan, 2017) or ethics education (Banerjee & Mitra, 2018), most attempts at curbing corruption focus on the probability and size of a punishment (Abbink & Serra, 2012). Despite the amount of research interest in the effects of these two factors, the results remain mixed and inconclusive (Boly & Gillanders, 2018), possibly because many studies employ one-shot tasks and explore only a limited number of combinations of punishment probabilities and sizes.…”
