I loved this class. Prof. Mattli has an unusual lecture style, but somehow he manages to be incredibly engaging. The topic matter (which ranged from the creation of the EU to GATT to globalization to property rights theory) is also incredibly interesting. He is very nice and encourages students to utilize his office hours. the only thing is class often started late or class time was reduced because he took so many student comments and spent a lot of time reiterating what was covered the week before. overall, if you haven't taken an international political economy course before and want the basics, i'd highly recommend it.
