Comparison of few National Economies with USA Cities and Provinces

Comparison of few National Economies with USA Cities and Provinces:

One of our Professor Mark J. Perry has compared the USA -Cities and Provincial Economies with the National Economies of UAE, Qatar, Syria, and other countries. As I found this to be great and interesting comparison I am putting his URL here. Anyone may visit his blog and see it.
