Paul Collier of Oxford University talks with EconTalk host Russ Roberts about the ideas in his new book, Wars, Guns, and Votes, a study of democracy and violence. Collier lays out the incentives facing a dictator who is considering the seductive appeal of holding an election. He defends his empirical work that forms the basis for many of the policy ideas in the book. Collier then makes the case for international military intervention to support democracies in poor countries.
