Travels of a T-shirt - is pretty fun, written by a prof at georgetown - she explores the global economy (and the institutions that govern it) by following the creation, life, and death of your average t-shirt.
The Goal - is something you'll probably read in your ops class. the best textbook ever, the worst novel ever. i'm a closet ops geek, so i dug it.
Super Crunchers - is all about the way that math (mostly stats) is changing the way the world works. a decent look at regression and other tools.
Predictably Irrational is by a fuqua prof that is a total boy genius. it's behavioral econ.
No Logo is a bit dated but a lovely attack on globalization. if i weren't already too old, i'd grow up to be naomi klein.
