Part II examines the consequences of brain drain for the sending countries.

"Demonstrates that the study of international migration has really come of age. From acculturation to undocumented immigration, the authors consider more than three dozen concepts at the heart of migration studies. Clearly written in a highly readable style, the book is a valuable resource for students and scholars alike." - Nancy Foner, City University of New York "This very useful and authoritative compendium explicates thirty-eight concepts central to analysis of international migration. It is accessible to undergraduate students and even can enrich graduate courses. It nicely complements books like The Age of Migration or Exceptional People. Concision is a virtue!" - Mark J. Miller, University of Delaware This book provides lucid and intuitive explanations of the most important migration concepts as used in classrooms, among policymakers, and in popular and academic discourse. Arguing that there is a clear need for a better public understanding of migration, it sets out to clarify the field by exploring relevant concepts in a direct and engaging way. Each concept: Includes an easy to understand definition Provides real-world examples Gives suggestions for further reading Is carefully cross-referenced to other related concepts It is an ideal resource for undergraduate and post-graduate students studying migration in sociology, politics, development and throughout the social sciences, as well as scholars in the field and practitioners in governmental and non-governmental organizations.

"Based on static partial equilibrium analysis, the "new brain drain" literature argues that, by raising the return to education, a brain drain generates a brain gain that is, under certain conditions, larger than the brain drain itself, and that such a net brain gain results in an increase in welfare and growth due to education's positive externalities. This paper argues that these claims are exaggerated. In the static case, and based on both partial and general equilibrium considerations, the paper shows that (1) the size of the brain gain is smaller than suggested in that literature; (2) the impact on welfare and growth is smaller as well (for any brain gain size); (3) a positive brain gain is likely to result in a smaller, possibly negative human capital gain; (4) an increase in the stock of human capital may have a negative impact on welfare and growth; and (5) in a dynamic framework, the paper shows that the steady-state brain gain is equal to the brain drain so that a "beneficial brain drain" cannot take place, and a net brain loss is likely during the transition.

International migration, the movement of people across international boundaries, has enormous economic, social and cultural implications in both origin and destination countries. Using original research, this title examines the determinants of migration, the impact of remittances and migration on poverty, welfare, and investment decisions, and the consequences of brain drain, brain gain, and brain waste.

Diasporas play an increasingly prominent role in discussions on foreign assistance and development policy. Governments of migrant-sending countries are working to attract both the talents and resources of emigrants and their descendants while governments of aid-sending countries hope to improve the outcomes of development assistance by engaging the talents and expertise of diasporas. Independently of governments, many diaspora groups or individuals recognize profitable opportunities in their homelands or contribute their time, talents, and resources to improving the quality of life there. This volume examines the development impact of diasporas in six critical areas: entrepreneurship, capital markets, "nostalgia" trade and "heritage" tourism, philanthropy, volunteerism, and advocacy. It is the result of research commissioned by the U.S. Agency for International Development's Office of Poverty Reduction, Diaspora Networks Alliance. Contributors include Roberto Munster, Hiroyuki Tanaka, Carlyanna Taylor, and Aaron Terrazas.

The debate on the economic implications of skilled migration for the home countries is a long-lasting phenomenon. This issue has been discussed for almost fifty years. During this period, most of the scholars (eg. Bhagwati and Hamada 1974, Portes, 1976) believed that skilled migration is detrimental for the countries of origin, while the host economies benefited from the inflow of skilled labor. Thus the notion of brain drain - harmful for the developing economies, and brain gain - profitable for developed countries - came into being, and is still present in the literature. However, in the mid of 1990s, a new strand of research on skilled migration became visible. This new school - the new economics of brain drain - argued that brain drain must not be detrimental for the countries of origin. Under certain circumstances, migration of professionals from developing economies may be in fact a "blessing in disguise" - and the potential gains could be higher than costs. The economists (such as Mountford, 1997, Beine et al., 2001 and 2003, Stark, 2005) from the new economics of brain drain have renewed the discussion on the economic consequences of skilled migration. However, their optimistic view of brain drain has been heavily criticized. The paper presents the main propositions of this new approach. Then it discusses the claims of the opponents of new economics of brain drain and brings new explanations why the brain drain is detrimental: both on theoretical and empirical ground.
