Corruption is believed to be a major factor impeding economic development, but the importance of legal enforcement versus cultural norms in controlling corruption is poorly understood. To disentangle these two factors, we exploit a natural experiment, the stationing of thousands of diplomats from around the world in New York City. Diplomatic immunity means there was essentially zero legal enforcement of diplomatic parking violations, allowing us to examine the role of cultural norms alone. This generates a revealed preference measure of government officials' corruption based on real-world behavior taking place in the same setting. We find strong persistence in corruption norms: diplomats from high corruption countries (based on existing survey-based indices) have significantly more parking violations, and these differences persist over time. In a second main result, officials from countries that survey evidence indicates have less favorable popular views of the United States commit significantly more parking violations, providing non-laboratory evidence on sentiment in economic decision-making. Taken together, factors other than legal enforcement appear to be important determinants of corruption. Here's a link to the paper. Hat tip to Tyler Cowen, who proposes a pithier abstract: During a period of diplomatic parking immunity, the average Kuwaiti diplomat to the United Nations racked up 246 parking violations. No Swedish diplomat had any parking violations. This paper explores how that might possibly be the case. There's another finding that I thought interesting: In the aftermath of the September 11, 2001 attacks, there is a sharp ? though temporary ? drop in diplomatic parking violations, by roughly 80%. We find that countries with greater Muslim populations experience particularly sharp declines. We can only speculate about the exact causes of this change in behavior, but the fear of police harassment or negative media attention for the home country during that politically charged period is a possibility.
