"What do Lego and 18th century political economist Adam Smith have in common? Both show why Denmark has become the best country in the world for business."
So, as the quote says, Denmark tops the list, and usual suspects are there as well. This is a bit broader than an economic freedom ranking-- they value being able to take part in elections and having freedom of expression-- but it's still another stab at explaining growth at the country level, insofar that one ranking can do that. They look at 120 countries.
There's a paper to be had in simply aggregating all of these rankings-- Frasier, Heritage, Forbes' ranking, etc., and many large scale companies do their own analyses as well. I'd love to see it all in one place.
Denmark, by the way, might be the most underrated country that I've visited. Copenhagen is a great town, and a day trip to Helsingor to see Kronborg Castle is well worth the trek. And the Copenhagen airport has hardwood floors. All considered, I'd return there before revisiting any other city except maybe Prague. Maybe I should do a top ten ranking of European cities...
