The World Economic Forum is one of those nebulous organization that publishes information and lists like this (most competiveness economies). They have a mysterious compound in Switzerland. One halfway expects to see armed guards milling around as the top of the building opens and a death ray machine pops up....
Here's a good link to more detailed country information and how they made the list. In between sipping Tokay and dispatching Number Two to a sauna in the English countryside.
Nevertheless the snark, take a look at the list because it will give you some ideas about what makes a good economy and how to sift different factors in the information soup.
FWIW. Reading other people's analyses will help you with your own.
