William Easterly. The Elusive Quest for Growth: Economists' Adventures and Misadventures in the Tropics. MIT Press, 2001 [Amazon/SLU]. An accessible book discussing modern growth theory. You need to read this if you hold to the 19th century view that development is a matter of international capital flows.
Paul Collier. The Bottom Billion: Why the Poorest Countries Are Failing and What Can Be Done About it. Oxford University Press, 2007 [Amazon/SLU]. A very readable book which distinguishes between the problems of most developing countries and those failed states at the bottom with a combined population of about a billion.
P. J. O'Rourke. Eat the Rich. Grove/Atlantic, 1999 [Amazon/SLU]. A very funny book. Despite claiming complete ignorance of economics, O'Rourke asks the right questions and gets the answers about 90% correct -- better than most development scholars.
Rohinton Mistry. A Fine Balance. Vintage, 2001 [Amazon/SLU]. A novel set in 1970s India. No economics but communicates the sense of powerlessness of the poor. A Booker Prize finalist and Oprah Book Club selection.
Pietra Rivoli. The Travels of a T-Shirt in the Global Economy: An Economist Examines the Markets, Power, and Politics of World Trade. Wiley, 2005 [Amazon/SLU]. A very accessible, straightforward way to learn about the economics of globalization without the usual polemics.
