This book was created by an interdisciplinary team of editors, co-authors and reviewers including historians, sociologists, psychologists, linguists and ethnologists, as well as experts in public policy, international business, marketing and entrepreneurship. This unique team (many of the authors are themselves diasporans with an extensive understanding of their topic) provides the first global academic platform on the subject, combining the latest empirical evidence from developing, emerging, transitional and developed countries with various combinations of diaspora flows that to date have received little attention.
