This article is from today's issue of the International Herald Tribune. I think it is a must read for any serious student if IB Higher Level Economics (but also for the interested Standard Level student who wants to go beyong textbooks).
Reading this article carefully may provide the IB Econ student with ideas on how to evaluate theory or a statement. There may be arguments against large budget deficits and expansionary fiscal policy but the seriousness of these arguments must be weighed against the specific circumstances.
