Individuals migrate when the dis- The movements of migrants clearly are in the appropriate direction, but we do not know whether the numbers are sufficient to be efficient in correcting income disparities as they emerge. New York: Modern Library. 6 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. First, the critics agree that it is not a theory as such, but rather a conceptual framework for classifying the various factors that explain migration. Cloud State University, St. It presents, firstly, quantitative magnitudes and describes some institutional regulations, AbstractThis paper analyses the determinants of migrations and the relation between them and the process of (1998). There is a strong presumption that they are not. The considerable merit of these approaches is to have added the notion of expected gains or, in the words of Sjaastad, the expected net return on investment. He also shows how these theories have evolved to take account of changing local and international migration dynamics. PICH Victor, "Contemporary Migration Theories as Reflected in their Founding Texts", The economic effects of immigration: structural, macro approach in developed countries, Migration and development: the case of developing countries, The micro-economic effects of immigration, Political effects: the case of refuge migration, The social effects of migration: minorities versus majorities. (2007). Veenhoven, R. (1996). 15As mentioned earlier, a characteristic inherent to the systemic approach is that of circular migration, a notion theorized by Burawoy (1976*). For Sjaastad, it is particularly useful to employ the human capital concept and to view migration, training, and experience as investments in the human agent. European Economic Review, 37, 452461. INTRODUCCIN. . They also stated that there is no all-encompassing theory to explain international migration. Journal of Political Economy, 64, 416425. Family migration decisions. 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. The main feature of enclaves is their high proportion of immigrant workers working for businesses belonging to other immigrants (Light, 1972). Until today, this western-centric approach has remained central to the conception of social change and development in demography. It is interesting to note that at around the same date, in fact a year before Burawoy, Claude Meillassoux (1975), not cited by the author, had proposed the same approach for the African context, articulating domestic and capitalist modes of production, and the separation of the two functions (reproduction and maintenance of the labour force). 40These ideas have not been widely developed since the work of Zolberg, Suhrke and Ahuayo in the 1980s. But Gary Becker (1964) was the one to explicitly formulate an inte grated investment approach in human capital theory. 45Carens starts out from the principle that birthplace and parentage are natural contingencies that are arbitrary from a moral point of view. Journal of Political Economy, 82, 10631093. Differential migration, networks, information and risk. 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. Costs can be broken down into money and non-money costs. In her view, immigration is a primarily urban phenomenon, concerning the major urban centres of the developed world. In practice, migration management involves a series of measures for more effective policing of borders, including measures to intercept migrants before they reach their destination. All twentieth-century migration policies were founded on a supposedly unshakeable principle: immigration is a privilege and not a right. American Economic Review, 69, 106116. This approach was later developed widely in research on migration in developing countries, particularly with regard to survival strategies and migrants capacity to become actors of change (De Haas, 2010). Journal of Population Economics, 1, 5770. Altogether, Sjaastad's model accounts for four aspects of the migration investment decision: (i) the imperfect synchronization of migration's benefits and costs over time; (ii) earnings differences between origin and destination locales; (iii) cost of living differences between the origin and destination; and (iv) the migrant's rate of time Happiness: Lessons from a new science. How will national and supranational states respond to these new needs? A second problem is more fundamental: evaluation studies consider the short term, yet the full benefits become visible only in the medium and long term (Goldin et al., 2011). Bhagwati, J., & Srinivasan, T. (1974). In: J. Frankel (Ed. I. It nonetheless gives rise to a conception of international migration that ties in with globalization, even suggesting the idea of a world labour market in a globalized economy (Petras, 1981; Simmons, 2002). somlim "" . Unfortunately, scientific research on this type of migration is scarce. 50In his view, migrants in illegal employment are one component of the underground economy, but they are not its cause. These are precursors of the research questions that were set to dominate the scientific literature on international migration in the context of globalization. In order to understand a Giddensian theory of migration, six key concepts must be addressed and defined. 24This approach centred on networks and social capital as positive factors has been criticized, by Krissman (2005) among others. (1989). Explaining U.S. immigration, 19711998. 1. While postmodernism has never held sway in demography,[2] two research currents have exerted a certain influence in the field of migration theory. For an overview of the state of human trafficking across the world, see Laczko and Gozdziak, 2005. Journal of Economic Literature, 13, 397433. It is only after migration has begun that a variety of self-reinforcing mechanisms come into play that perpetuate and expand the migration flows over time, feeding back on community structures to promote its cumulative causation. In conclusion, to the extent that the causes are international, the solutions also call for action at the international level. On migration and risk in LDCs. Shaping the world economy. ), Crossing borders: Regional and urban perspectives on international migration. It is as if the microeconomic hypothesis of the rational individual maximizing his interests has become a postulate that needs no verification. 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. 35But Wilson and Portes most original idea concerns the third mode of incorporation, the ethnic enclave which comprises groups of immigrants concentrated in a specific geographical area who set up businesses to serve their own ethnic market and/or the general population (Portes, 1981). The Economic and Social Review, 27, 119. It is a pioneering study which aims to clarify the various definitions and typologies and, above all, to place migration theories in their historical context. (1978). The second direction of research, linked to the first, has spawned numerous studies on transnationalism (Vertovec, 2009). Lall, S., Selod, H., & Shalizi, Z. It is the interplay of these two processes that drives the circular system. 7Sjaastads paper laid the groundwork for the general schema for migration presented by Everett Lee in 1966*.

The Determinants of International Migration: Theory. Mincer, J. Oberai and Manmohan also mention that the relative effect of remittances is strongest for the poorest households. The second point concerns the period covered, namely the decades from the 1960s up to the year 2000. In J. Abowd & R. Freeman (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? 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. [1] Before proceeding further, two points must be made clear. 34One of the conceptual weaknesses of research on migrant economic integration, in both developed and developing countries, is to consider the labour market as unique. Lobjectif de cet article est de rendre compte de lvolution des thories migratoires contemporaines partir de 20 textes fondateurs et regroups pour la premire fois dans un manuel (Pich V., 2013, Les thories de la migration, Ined). A second current, linked to postcolonial studies, examines the consequences of transferring the human and symbolic colonial legacy to the heart of the metropolis. Journal of Urban Economics, 6, 135147. While the determinants of persecution, based on the Geneva Conventions definition of refugees, are internal to the country in question, external effects may also exist in the form of factors that aggravate economic and social conditions, thereby increasing the likelihood of conflicts that generate refugee movements. Bauer, T., & Zimmerman, K. (1998). While there is a strong tendency in the literature to distinguish between domestic (internal) and international (external) migration, there is actually just one economic theory of migration. Journal of Regional Science, 43, 139165. 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. Greenwood, M. (1985). This critical approach has been applied to question the official categories produced by censuses, notably racial and ethnic categories (Nobles, 2000; Simon and Piche?, 2012). Immigration can have a major impact on the entire economic structure, including labour-force participation rates, population skill levels, quantity and quality of capital, and organization of production (Carter and Sutch, 1999) Another more recent review of the effects of immigration in developed countries concludes that they are generally positive, in terms not only of growth, but also of innovation and tax revenue (Goldin et al., 2011, chapter 6). For Krissman, networks include many other stakeholders who serve as intermediaries, either at national borders, or in the regions of destination. Corden, W., & Findlay, R. (1975). viewpoint. Chicago: University of Chicago. Pessino, C. 1991. We also discuss other models that focus on how the immigration decision is influenced by family considerations, the option value of waiting, and feelings of relative deprivation. Deardorff, A. Journal of Regional Science, 25, 521544. The above theory is verified by laboratory experimental thermal imaging results of moisture migration of siltstone from the Mogao Grottoes cliff. 19Up to this point, the migration literature focused essentially on men.
