Paul Collier

Paul Collier (Wikipedia) is a development economist at Oxford University, most famous for his development economics book The Bottom Billion. In October 2013, Collier’s book Exodus: How Migration is Changing Our World (Amazon Kindle, Wikipedia) was released.

The book included a model of diaspora dynamics to predict migration flows: the claim was that migration flows from a region would initially be small, but they would pick up as the size of the diaspora increased.

Collier’s book discussed many issues such as social capital decline, nativist backlash, and brain drain.

A detailed list of responses to Collier’s book is available on the Wikipedia page. Here, we list the main responses from the open borders angle:
