Tiebout, C. (1956). Sjaastad, (1962) presented Human capital theory, in which migration is defined as individual's investment decision (cited by Bauer and Zimmermann, 1999) because individual increases employment perspective or/and uses opportunities of foreign education. Yet while these major classics have marked the social sciences, their contributions to the field of migration are few. Tinbergen, J. In short, alongside the human capital so dear to neoclassical theory, network and kinship capital also exists (social capital). (2006). 3Our first question concerns the very definition of migration. Journal of Regional Science, 25, 521544. Amsterdam: Elsevier. A model of labour migration and urban unemployment in less developed countries. 48Ghoshs approach has given rise to a new paradigm, that of migration management, to achieve more orderly, predictable and humane objectives through global governance of the migration regime. (1986). In C. Gorter, P. Nijkamp, & J. Poot (Eds. The emergence of migration theory and a suggested new direction. The existence of networks leads to the creation of a social capital, a notion that explains why and how belonging to a network increases the probability of migrating: thanks to network resources, the costs and risks of migration diminish while the benefits increase (Palloni et al., 2001). 47Rather than addressing the root causes that generate or fuel pressures for disorderly migration in sending countries or that attract migrants to the receiving ones through irregular channels, governments have responded by adopting repressive and restrictive measures. Review of Economics and Statistics, 89, 359373. Economic Inquiry, 26, 2341. He also shows how these theories have evolved to take account of changing local and international migration dynamics. El cuadro analtico que aqu se propone presenta la migracin como un fenmeno multifactorial y multidimensional que integra tres dimensiones principales: el origine y el destino, los niveles de anlisis micro, meso, macro y global, y las dimensiones econmicas, sociales y polticas. 49It is the fear of huge waves of illegal immigration that shapes some areas of current political discourse and that serves to justify restrictive measures. Whether migration occurs across internal or international borders is largely irrelevant from a theoretical standpoint, as both types of flows are primarily driven by a desire to exploit geographic variation in the return to labor. In the human capital theory, migration is considered as an investment in the human agent which involves costs and returns (Sjaastad 1962 ). There is a strong presumption that they are not. NBER Working Paper No. The discourse of the extreme far-right political parties emerging in many parts of the world is based, among other things, upon an anti-immigration stance, sometimes linked to Islamophobia. Migration management calls for coordination between governments. Researchers no longer focus on the situation in immigration regions, but rather on the links between emigration and development in the emigration regions. Geneva: International Labour Organization. The fundamental premise of nearly all the models discussed is that migration is driven by spatial differences and distributional differences in the net returns to human labor. reality but did not change core of the original theory. The temporary work programmes now re-emerging in industrialized countries also involve a twin economic and institutional dependency. This attention reflects both the importance of the flows and the complexity of the behaviour. In G. DeJong & R. Gardner (Eds. (1989). Journal of Political Economy, 74, 132157. However, the existence of an underground economy makes it easier to recruit illegal migrants, helped by migrant networks who smooth their entry into the informal labour market. A new approach to consumer theory. somlim "" . She also focuses on the relationship between gender and networks in migration, stressing that the gendered division of labour must be included in any account of the social relations of production in a society. For an overview of the state of human trafficking across the world, see Laczko and Gozdziak, 2005. A new approach to the economic theory of fertility behavior. This negative viewpoint was reiterated in research on migration and development, a point we will discuss in the next section. Agency, Structure, the Duality of Structure, Institutions, the This provides a means to sidestep the fragmentary nature of the demographic field by calling upon the notion of demographic regime. As stated above, rather than competing, each approach brings specific new insights that must be taken into account when attempting to explain migration.

Sjaastad Published 1 October 1962 Economics Journal of Political Economy Migration research has dealt mainly with the forces which affect migration and how strongly they have affected it, but little has been done to determine the influence of migration as an equilibrating mechanism in a changing economy. Hatton, T., & Williamson, J. It is Sassen who can take credit for developing the concept of the global city from where the world economy is managed and serviced. Theoretical justifications for the gravity model of trade have been provided by Linneman (1966), Anderson (1979) and Deardorff (1998). Based on the work of Sjaastad (1962) migration is treated as an individual investment decision to increase the productivity of human capital, thus again focusing on the labour market, but at the same time explaining the selectivity of heterogeneous migrants. (2005). This helps to explain the relative magnitudes of observed gross and net migration. 23The network approach also underpins the model of cumulative causation proposed by Douglas Massey (1990*). But in all cases, these effects are small, or even negligible (Card, 2009). Stark, O., & Yitzhaki, S. (1984). Under this paradigm based, moreover, on the principle of national sovereignty in migration policy these policies are shaped by the economic needs of the countries concerned, and hence focus mainly on the labour market. This methodological shortcoming is linked firstly to the huge number of parameters to be included in the models which, as yet, have defeated all attempts at empirical implementation. 19952002. An important contribution was by Sjaastad , who articulated a theory of internal migration as a type of human capital investment. McCall, B., & McCall, J. This is a paradigm that extends beyond the purely utilitarian outlook, by proposing that questions of migrants rights be included among the political parameters of migration. Fawcett, 1981) New Economics . Unfortunately, scientific research on this type of migration is scarce. Quality-of-life in individualistic society: A comparison of forty-three nations in the early 1990s. Regional and urban perspectives on international migration: an overview. The first selected text is by Alan Simmons (1987*). Amenities and rural development theory, methods and public policy. Our Natalia Banulescu-Bogdan discusses with researcher Justin Gest (author of "Majority Minority") the ways in which the confluence of polarization, nationalism, and immigration seen today can be interpreted. Both micro (neoclassical) and macrostructural theories of migration are re-viewed. 52We have presented the various theoretical approaches by examining the paths along which new ideas unfold. In a paper published in 2006, Portes and Shafer responded to these criticisms by concluding that the ethnic enclave approach was still valid. The costs and returns of human migration. PubMedGoogle Scholar, Bodvarsson, .B., Van den Berg, H. (2013). ), Immigration, trade, and the labor market. Another important notion in Masseys text is the distinction between the processes that initiate migration and those that maintain it. Challenging the postulate of the rational actor maximizing interests under market forces, Burawoy introduced political and structural factors. Curiously, the first dimension has rarely been studied in developed countries, as if the positive effects of migration at individual level could be taken for granted. Wilbur Zelinski (1971*) was among the first to outline a theory of mobility based on the notion of transition so dear to demographers. The most problematic aspect of these studies is of a methodological nature. Hedonic prices and implicit markets: Product differentiation in pure competition. Village-community ties, village norms, and ethnic and social networks: a review of evidence from the third world. But it also affects the levels of analysis, be it micro, macro or meso. Is there a fundamental contradiction here between neo-liberalism, which promotes free circulation of capital, goods and services, and the new protectionist model of migration management based on flexibility and circularity? Borjas also shows that if the arrival of new immigrants on the labour market does have an adverse effect, it is on the pre-existing immigrant population, and on the least skilled native workers. This new paradigm involves replacing the concept of migration with that of mobility, the latter being the most advantageous situation for optimizing profit (Pellerin, 2011). For Tapinos, this must be multilateral management; it would be anachronistic to address immigration control exclusively in terms of sovereignty. The second direction of research, linked to the first, has spawned numerous studies on transnationalism (Vertovec, 2009). A theoretical foundation for the gravity equation. New York: Twentieth Century Fund. On voit ainsi se dvelopper des thories qui, privilgiant dabord des approches micro-individuelles centres sur lanalyse cot-bnfice, vont peu peu intgrer les facteurs macro-structurels. This also explains the substantial divergence between results sometimes positive, sometimes negative, and sometimes indeterminate. International Migration Review, 23, 457485. Hence, the actors involved in migration networks are not always facilitators; some may also be exploiters. (2002a). She examines the reorganization of industrial production, as reflected in the proliferation of sweatshops exploiting undocumented workers, and of industrial homework. Journal of Labor Economics, 5, 452476. Happiness: Lessons from a new science. Yap, L. (1977). Harris, J., & Todaro, M. (1970). Because native workers and immigrants are not interchangeable in the production process. 12Zelinskis approach is most commonly criticized for its evolutionist outlook, based on the theory of modernization. The second current concerns the effects of immigration on national identities.

This fragmentation is especially discernible in an area that has dominated migration research, namely the distinction between the causes and effects of migration. Together, they bear witness to the emergence of theories which, after initially focusing on micro-individual approaches centred on cost-benefit analysis, gradually move on to incorporate macro-structural factors. According to Carter and Sutch (1999), whose study covers the entire twentieth century (1820-2000), the beneficial aspects of migration are clearly discernible. In M. Rosenzweig & O. Stark (Eds. The economic theory of cross-border migration is concerned with three questionswhy migrate, who migrates, and what are the consequences for source and destination countries? They also stated that there is no all-encompassing theory to explain international migration. Without doubt, Sjaastad's greatest contribution was to introduce the notion of human capital into migration theory to get around the problem of estimating returns. THE HUMAN CAPITAL MODEL OF MIGRATION Many models of migration have a thin base of theoretical support and are difficult to relate to the body of microeconomic the-ory.
