How the Perception of Corruption Shapes the Willingness to Bribe: Evidence From An Online Experiment

Abstract

Abstract Does the perception of corruption shape the willingness to bribe? This study evaluates the socio-psychological determinants of corruption by measuring how different types of messages influence the probability of engaging in corruption for access to public health, social programs, and official documents. This research uses the social norms approach to explore the link among messaging, perception, and behavior. An online experiment was conducted in Peru for two weeks between October and November 2021, using social media (Facebook) to recruit participants (n = 2584). The participants were divided into two treatment groups and one control group. Those in the treatment groups received informational displays on (i) the perception of corruption as widespread in the public sector (descriptive norm) or (ii) corruption as morally wrong (injunctive norm). The control group did not receive a message. Exposure to messages on corruption increased the overall probability of engaging in corruption. Unexpectedly, those in the injunctive norm group increased their willingness to bribe. Furthermore, this study also found significant differences in bribing behavior based on the different types of public service, gender, and age.
