I like
the www.cia.org because it gives country reports that include growth and development statistics
www.IMF.org I like their article IV reports which show the IMF's annual economic reviews of countries
I like the Moody's and Standard and Poors websites although you normally have to be a subscriber to access the country reports
The Economist intelligence unit is another subscription that is very useful which produces great country reports
For teaching I like www. tutor2u.net and www.econclassroom.com and well as Ted talks

I recommend the following articles
www.ncpa.org/sub/dpd/index.php?Article_ID=23658
and
www.bbc.co.uk/news/business-13798000 Eurozone Crisis Explained

I like the economics IB notes provided at www.tutor2u.net/revision_notes_economics.asp and on www.econclassroom.com
