This is from the Altman blog Managing Globalization. Read Bhagwati and Jeff Sachs explaining what is going on. BTW, we just got for the library the new Sachs book Common Wealth: Economics for a Crowded Planet.
Also read Rodrik's post on Food prices and poverty: confusion or obfuscation? (a bit more demanding - but you are really great students, interested and ambitious!)
