Parking Tickets and Corruption.

Some guys dig new ways of discovering the ways of world. 2 guys did a study of unpaid parking tickets to legally immune Diplomats from various countries. And they found a correlation between their behaviour and corrption back home.
Their findings in their own words.

"5. Conclusion
We exploit a unique natural experiment – the stationing in New York City of thousands of government officials from 146 countries from around the world – in a setting ofzero legal enforcement of parking violations to construct a revealed preference measure of official corruption. We find that this measure is strongly correlated with existing measures of home country corruption. This finding suggests that cultural
or social norms related to corruption are quite persistent: even when stationed thousands of miles away, diplomats behave in a manner highly reminiscent of officials in the home country. Norms related to corruption are apparently very deeply engrained.
The second main empirical finding is the strong correlation between affinity for the United States in the diplomat’s home country and parking violations in New York. This provides real-world empirical evidence that sentiments matter in economic decision-making. Of course, in the case we study the punishment for parking violations was essentially zero (at least in the pre-November 2002 period),
allowing individuals to indulge their tastes without penalty.

Pakistan is at 10th position and India is at 69th position. Something wrong with study? Or probably, we really have good diplomats.
