If the productivity growth slows in the developed countries don't bother/can't afford to spend as much money on research in the field, maybe they should give it up all together? Comparative advantage doesn't exist for nothing. Maybe if the EU finally reforms its CAP and US drops its subsidies, and instead direct the money to developing countries in Africa to promote modernization and productivity growth in agriculture, everyone would profit - the developing countries from investment, everyone else from lower food prices. Instead, we get a lose-lose situation as described in the article, which is the complete opposite of how Stiglitz (quite convincingly) argues globalization should work.
If this were a less academically-inclined blog, I'd feel a lot less resentment from using this meme to describe my feelings:
/facepalm
PS: No, I am not making lots of blogposts just to fill a "quota" after 2 weeks of silence during midterms ^_____^
