Yep. An interesting paper on the subject was done a few years ago:

Abstract: 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
corruption based on real-world behavior for government officials all acting in the same setting.
We find tremendous persistence in corruption norms: diplomats from high corruption countries
(based on existing survey-based indices) have significantly more parking violations. 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 nonlaboratory
evidence on the role that sentiment and affinity play in economic decision-making.
