Who should be allowed to immigrate and who not is one of the most pressing questions of our time.

In Exodus, Paul Collier, bestselling author of The Bottom Billion, lays out the effects of encouraging or restricting migration, exploring this volatile issue from three perspectives: that of the migrants themselves, that of the people they leave behind and that of the host societies where they relocate.

Exodus confirms how crucial it is that we look squarely at the issues surrounding immigration, since so much depends upon finding a sound and workable policy.
