Roback, J. ), Migration decision making: Multidisciplinary approaches to microlevel studies in developed and developing countries. The need for highly skilled Two questions, in particular, must be studied in greater depth: What are the new manpower needs of the developed economies, and how will they evolve? I. In his 1977 JPE article with Daniel Wisecarver "The Social Cost of Public Finance" (Sjaastad, 1977), Larry developed a highly innovative normative theory of government that 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. Nations with scarce labor supply and high demand will have high wages that attract immigrants from nations with a surplus of labor. They are constantly recurring references, both in the theoretical frameworks used by scholars in their empirical studies, and in the numerous literature reviews offering critical overviews of these theories. The text by Zolberg, Suhrke and Aguayo (1986*) looks at refugee migration, a form of migration that was very common throughout the twentieth century and remains so today. Stark, O. Chicago: University of Chicago. Migration theories and evidence: An assessment. In G. Borjas & J. Pich V.. For an exception in the field of fertility and health, see Riley and McCarthy, 2003. 17This model challenges the classic approach linking development and migration, whereby development leads to emigration by destroying pre-industrial society and releasing manpower to work in new urban labour markets (Massey, 1988), and whereby migration, considered as a method for reallocation of resources, will eventually restore the balance between origin and destination areas (Todaro, 1969). Indeed, unlike immigration from Europe, migration from former colonies, designated as postcolonial, possesses specific features resulting as much from the shared experience of the colony as from the continued experience of the post-colony at destination, marked by ethnic and racial prejudice and by discrimination (Simon, 2010, p. 362). Internal migration in developing countries. London: Routledge and Kegan Paul. Hence, the massive arrival of immigrants from low-wage countries over the last fifteen years must be interpreted in the light of these transformations. Le cadre analytique propos ici prsente la migration comme un phnomne multifactoriel et multidimensionnel, qui intgre trois dimensions principales : lorigine et la destination; les niveaux danalyse micro, mso, macro et global; les aspects conomiques, sociaux et politiques. In C. Gorter, P. Nijkamp, & J. Poot (Eds. What matters here, is to introduce the question of rights as an integral component of migration policy (Pich, 2009). Ils sont lorigine davances significatives dans lexplication des migrations, leurs causes et leurs effets. He points up the absence of appropriate policies to address the new challenges of migration, notably the build-up of emigration pressure due to mounting inequalities. The attraction of cities: A review of the migration literature. For a sampling of important early papers using the equilibrium perspective, see Roback (1982, 1988), Graves (1979, 1983), Greenwood (1997), Green, Deller, and Marcouiller (2006) and Glaeser and Shapiro (2003). NBER Working Paper No. For Tapinos, it is employers who benefit the most. What can economists learn from happiness research? Social Indicators Research, 48, 157186. 1) Migration theory and the experience of a natural disaster in relation to migration Migration theories in general have focused on cost-benefit analysis (Sjaastad 1962 as presented in Speare 1974),the mover-stayer model . Layard, R. (2005). Linneman, H. (1966). In a paper published in 2006, Portes and Shafer responded to these criticisms by concluding that the ethnic enclave approach was still valid. Micro-level theories such as the neoclassical micro-migration theory, Wolpert's . Research on internal migration in the United States: A survey. 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). She thus subscribes to the distinction, established by Burawoy (1976) and Meillassoux (1975), between the public and private spheres, and above all, the necessary articulation between the two when analysing female migration strategies. According to the human capital theory of migration (Sjaastad, 1962), people are likely to move to regions with many employment opportunities. 45Carens starts out from the principle that birthplace and parentage are natural contingencies that are arbitrary from a moral point of view. The analytical framework developed here presents migration as a multifactorial and multidimensional phenomenon combining three main dimensions: origin and destination; micro, meso, macro and global analysis levels; economic, social and political aspects. 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. For an overview of the state of human trafficking across the world, see Laczko and Gozdziak, 2005. Molho, I. ), Studies in development economics and policy. This negative viewpoint was reiterated in research on migration and development, a point we will discuss in the next section. Neoclassical Theory of Migration One of the oldest and most commonly used theory used to explain migration is the Neoclassical theory of Migration. 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. They form the pieces of a puzzle, brought together in Figure 1. He also affirms that migration increases with time, and that this increase is driven by growing economic disparities between developed and developing countries, by education and training, and by technological progress, notably in communications and transportation. The second concerns the impact of migration on non-migrant populations and on the native-born inhabitants of destination countries. 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. Greenwich, CN: JAI Press. New York: Twentieth Century Fund. 40These ideas have not been widely developed since the work of Zolberg, Suhrke and Ahuayo in the 1980s. Immigration and self-selection. Explaining U.S. immigration, 19711998. A first current challenges the claim to universality of statistical categories, suggesting that categories are historically determined social and political constructions (Szreter et al., 2004; Cordell, 2010). Unfortunately studies of the long term are rare. Todaro, M. (1969). For a very recent and thorough review specifically of the literature on rural to urban internal migration in LDCs, see Lall, Selod, and Shalizi (2006). ), Regionalization of the world economy. El enfoque en trminos de relaciones gnero ocupa igualmente un lugar importante. Before deciding to leave their place of residence, individuals examine the costs and benefits of migrating. For Krissman, networks include many other stakeholders who serve as intermediaries, either at national borders, or in the regions of destination. Brookfield: Ashgate. Migration and the option value of waiting. In the human capital theory, migration is considered as an investment in the human agent which involves costs and returns (Sjaastad 1962 ). His analytical framework sought to identify all the elements liable to influence migration, ranging from the economic environment to technology, the social environment and political factors. Regional Science, 18, 131142. Like the classic theory of demographic transition, the theory of the mobility transition (Zelinski speaks more modestly of a hypothesis) forms part of the theory of modernization that dominated in the 1970s. 19952002. Second, even though Zelinskis presentation of the demographic (or vital) transition is now largely outdated, that of the mobility transition remains pertinent, especially in its advanced phase. Journal of Regional Science, 23, 541546. But Gary Becker (1964) was the one to explicitly formulate an inte grated investment approach in human capital theory. Beyond measurement problems, debate often focuses on the economic impact of irregular migration. But in a more general perspective, certain authors see migration as a response to demand for labour. His text highlights some of the inadequacies of existing migration policies and practices, and argues in favour of a more comprehensive, balanced and transparent multilateral regime to manage migration. The second dimension, on the other hand, has become a central issue, focusing on three questions: How does immigration affect the earnings and labour market opportunities of native residents? And above all, for how long will this contradiction persist? Under this theory, the mere consideration of gender as a variable among others is not enough; it must be developed as a central concept (Boyd, 1989*; Pessar, 1999; Lutz, 2010). (2003). How can increasingly diverse societies come up with a new definition of "we" that is both m They represent landmarks of demographic thought, and provide new insights for analysing and understanding demographic processes. McCall, B., & McCall, J. Dichos textos estn al origen de avances significativos en la explicacin de las migraciones, de sus causas y de sus efectos. Aparecen as teoras que, privilegiando primero los enfoques micro-individuales centrados en el anlisis costos-beneficios, van integrando poco a poco los factores macro-estructurales. New York: Modern Library. These are precursors of the research questions that were set to dominate the scientific literature on international migration in the context of globalization. Tiebout, C. (1956). Micro-individual theories focusing on economic rationality and the notion of equilibrium were pitted against macro-structural theories centred on demand for migrant labour generated by developments in the world capitalist economy (Wood, 1982). 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. Becker makes it clear that migration is an act of investment in ones human capital when he states The many forms of such [human capital] investments include schooling, on-the-job training, medical care, migration, and searching for information about prices and income (our italics). 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 Journal of Labor Economics, 4, 131149. Princeton, NJ: Princeton University Press. 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. Ruralurban migration in developing countries: A survey of theoretical predictions and empirical findings. w7487. 54Two dimensions of migration deserve to be more fully theorized in the future. Cloud State University, St. They must all be considered when seeking to explain migration or to assess migration policy. Chicago: University of Chicago Press. Fawcett, 1981) New Economics . Southern Economic Journal, 58, 392405. Una nueva dinmica comienza a ser evidente en los municipios de Cundinamarca como resultado de las restricciones de habitabilidad impuestas por el mercado a una buena parte de la poblacin. Vous avez t dconnect car votre compte est utilis partir d'un autre appareil. 53The most recent founding text presented here dates back to the year 2000. (Sjaastad, 1962; T odaro, 1970; Borjas, 1980) Value-expectancy (DeJong and . But in all cases, these effects are small, or even negligible (Card, 2009). 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. Il est interdit, sauf accord pralable et crit de lditeur, de reproduire (notamment par photocopie) partiellement ou totalement le prsent article, de le stocker dans une banque de donnes ou de le communiquer au public sous quelque forme et de quelque manire que ce soit. Mabogunjes approach sees migration not as a linear, one-way movement, but as a circular phenomenon embedded in a system of interdependent variables. 2This article explores the development of contemporary migration theories as reflected in some twenty founding texts that have marked the field over the last fifty years. For Castles, multicultural models appear to offer the best solution, but there are substantial obstacles to their realization. Bauer, T., & Zimmerman, K. (1998). Lanalyse des rseaux migratoires occupe une place centrale aussi bien dans les cadres explicatifs que dans les travaux propos des effets de la migration sur le dveloppement conomique. Scottish Journal of Political Economy, 33, 396401. Journal of Political Economy, 70, 8093. 36More recent research has sought to challenge the ethnic enclave approach. Does this signal a recent absence of major theoretical developments in migration studies? 51The period 1960-1980 has often been seen as a time of confrontation between competing migration theories, each claiming supremacy. Journal of Political Economy, 64, 416425. In his view, the idea that immigration reduces the economic well-being of current citizens is not a valid argument for imposing restrictions. All twentieth-century migration policies were founded on a supposedly unshakeable principle: immigration is a privilege and not a right. Migration is not, therefore, an isolated strategy, but ties in with other demographic behaviours (Gregory and Piche?, 1985; Mertens, 1995). Why is this so? Happiness and economics. Runciman, W. (1996). The decision to grant formal refugee status to citizens of a particular country is generally seen as an implicit condemnation of the government of that country for persecuting its citizens or failing to protect them. This process is experimental and the keywords may be updated as the learning algorithm improves. World Bank Policy Research Working Paper 3915. The network as an element of social structure is a notion used by Massey to establish a link between networks and the effect of feedback on migration. The neoclassical approachwhich aligns with Sjaastad's theory of migration between urban and rural areasis criticized by Kurekova, who states that it has "mechanically reduced migration . A selection of papers, articles and book chapters spanning several decades, many of which were first written in English, have been translated into French and brought together in a book published by INED as part of a new series devoted to the founding texts of demographic theory. Differential migration, networks, information and risk. Amsterdam: North-Holland. Science, 237, 733738. 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). 6Without doubt, Sjaastads greatest contribution was to introduce the notion of human capital into migration theory to get around the problem of estimating returns. The re-emergence of guest worker programmes is currently receiving strong support, not only from international organizations such as the International Labour Organization and the International Organization for Migration, but also from scholars (Piche?, 2012). First, political factors have been studied mainly in cases of refugee movements; second, the effect of migration on diversity, in terms of the relations between minorities and majorities, is a key political issue at the heart of the identity debate. The special issue of the International Migration Review on female migration, edited by Mirjana Morokvasic (1984*) points out that migration also concerns women. Economica, 42, 5978. 12Zelinskis approach is most commonly criticized for its evolutionist outlook, based on the theory of modernization. 55The second dimension to be more fully integrated in migration theory concerns migrants rights. Distribution lectronique Cairn.info pour I.N.E.D I.N.E.D. Individuals migrate when the dis- How will national and supranational states respond to these new needs? His most important conclusion is that the methodological arsenal of modern econometrics is incapable of providing a single shred of evidence to prove that immigrants have a substantial and adverse impact on the earnings and labour market opportunities of US natives. This has not always been the case, as the text by Oberai and Manmohan (1980*) shows. A sequential study of migration and job search. Rosen, S. (1974). He seeks to include migration in the theory of demographic transition which traditionally focuses solely on changes in fertility and mortality. Happy life-expectancy: A comprehensive measure of quality-of-life in nations. Analysis of migration networks is a key component of explanatory frameworks and of studies to determine the effects of migration on economic development. regional convergence of per capita income in Spain during the period Most studies of migration determinants investigate the impact of. In M. Rosenzweig & O. Stark (Eds. For Carens, free migration may not be immediately achievable, but it is a goal towards which we should strive. 32There are two dimensions to the effects of migration at micro-individual level. Hedonic prices and implicit markets: Product differentiation in pure competition. In short, if households cannot surmount the structural obstacles to development (access to credit, trust in institutions, migration policies favourable to investment, etc. The first asks the question: is the migration experience positive for migrant men and women? It is the interplay of these two processes that drives the circular system. Demography, 26, 114. Journal of Development Economics, 4, 239264.
