Replication Data for Institutions, Norms and Accountability: A Corruption Experiment with Northern and Southern Italians

Anti-corruption research has highlighted the potential for grassroots monitoring to improve governance outcomes, but the conditions under which citizens are willing to report bribery remain under-studied. Are individuals from some societies socialized into a "culture of corruption" that makes them more accepting of malfeasance, or is the failure to denounce wrongdoing simply a response to low-quality enforcement institutions? I conduct a laboratory experiment to examine how the propensity to report corruption differs between Northern and Southern Italians, two populations experiencing different levels of corruption in everyday life. For each group, I experimentally manipulate the quality of enforcement institutions. When given high- quality institutions, all participants are more willing to report corruption. Moreover, Southerners and Northerners behave similarly when placed within the same institutional environments. These results suggest that high-corruption societies are not "culturally" predisposed to tolerate malfeasance. Rather, improving the capacity of enforcement institutions may significantly strengthen accountability norms.
