In my economic development class I have my students read Paul Collier's The Bottom Billion. In the book Collier outlines 4 traps to economic development (Civil War, Being Landlock, Overreliance on natural resources, and bad government). I like his straight forward approach, and he does a good job of emphasizing the macro trends in a country.
Collier has a new book (War, Guns, and Votes) out I haven't had a chance to read.
If you want to follow more of Collier's work he is now bloging occasionally (here), but this wesbite also seems to link to his other Op-Eds.
Tomorrow I'll talk about Bill Easterly who writes another book I have my students read.
