This revised and updated book provides unique insight into cross-border labor mobility, from the ancient forms of slavery to the present day. With a focus on the economic factors that underpin human mobility across the world, it charts the different forms of migration from African and Amerindian slaveries, to modern global migration and human trafficking. By highlighting the economic and political conditions that drive human mobility and anti-immigrant sentiments, a nuanced and detailed understanding of the drivers of forced and voluntary cross-border mobility are presented. This book presents a multidisciplinary understanding of the patterns and processes that define human mobility. It will be of interest to students, researchers, and policymakers working within labour economics and migration studies. Caf Dowlah is a Visiting Scholar at the University of Miami Law School.
