The Bottom Billion

Paul Collier, an Oxford development economist and former World Bank research director, argues that the development problem is no longer about poor countries generally. Most of the developing world has been converging on rich-country incomes; roughly a billion people live in about sixty countries that have not, and those countries are the actual problem.

His explanation is four traps, each supported by his own econometric work. The conflict trap: civil war destroys income and low income raises the probability of civil war, producing a cycle, and post-conflict countries have high relapse rates. The natural resource trap: resource revenues undermine governance, distort the exchange rate against other exports, and raise the value of capturing the state. The trap of being landlocked with bad neighbours: a landlocked country's growth depends on its neighbours' infrastructure and policy, which it cannot control. The trap of bad governance in a small country: reform requires a critical mass of educated people and a scale of market that small failing states lack.

His policy proposals go beyond aid: military intervention under specified conditions, international charters governing resource revenue, budget transparency and post-conflict conduct, trade preferences designed to help these countries specifically, and better-targeted aid. The book is written for a general audience and states its findings more confidently than the underlying econometrics support; Collier's methods have been criticised, particularly the identification in the conflict work. The framing of a distinct bottom group with specific structural problems has been widely adopted.
