My research revolves around the question how to prevent illegal behavior, corporate fraud in particular, in a (cost)effective manner. When studying this question, I focus on how situational factors affect behavior. For instance, an analysis of the universe of Coast Guard surveillance flights shows that if shipping crews discharge oily substances into the sea, they do so after sunset - when they are sure not to be convicted in court even when caught. In a completely different context, and based on a long-running field experiment at the Royal Palace in Amsterdam, I show that people are less likely to soil the street when exposed to light.
