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). Science, 237, 733738. 54Two dimensions of migration deserve to be more fully theorized in the future. They form the pieces of a puzzle, brought together in Figure 1. Urban unemployment and wage determination in LDCs: Trade Unions in the Harris-Todaro Model. The inaugural volume of this series was edited by Victor Pich. How will national and supranational states respond to these new needs? Neoclassical Theory of Migration One of the oldest and most commonly used theory used to explain migration is the Neoclassical theory of Migration. His discussion of the communitarian principle, whereby exclusion is justified by the right of communities to self-determination, brings him to the question: If freedom of movement within the state is so important that it overrides the claims of local political communities, on what grounds can we restrict freedom of movement across states? He goes even further, stating a principle also advanced today in the case of temporary migrant workers: It is right to assert that our society ought to admit guest workers to full citizenship. Both micro (neoclassical) and macrostructural theories of migration are re-viewed. 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. 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. He sees migration as an investment increasing the productivity of human resources, an investment which has costs and which also renders returns. In short, they show that the dynamics leading to the inception of social conflicts are not purely internal, but transnational, and that as conflicts develop, they tend to be further internationalized. 39The authors also discuss refuge migration in the global context, with its enormous asymmetries in terms of power and wealth across different regions of the world. Princeton, NJ: Princeton University Press. 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". 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. Gorter, C., Nijkamp, P., & Poot, J. While postmodernism has never held sway in demography,[2] two research currents have exerted a certain influence in the field of migration theory. Lees model introduces the original concept of intervening opportunities between the places of origin and destination. Until today, this western-centric approach has remained central to the conception of social change and development in demography. An exception is the approach taken by Sjaastad [11] who began a tradition of treat-ing migration as an investment in human capital. New York: Pergamon Press. Throughout history, each society has developed demographic reproduction strategies by combining the reproductive mechanisms of fertility, mortality and migration. 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. Journal of Economic Literature, 10, 159198. According to Carter and Sutch (1999), whose study covers the entire twentieth century (1820-2000), the beneficial aspects of migration are clearly discernible. ), Research in human capital and development (Vol. 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. 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). Tinbergen (1962) first applied the gravity model of trade to explain international trade patterns, and trade economists have consistently found it to explain a large proportion of the variation in trade flows, making the model attractive for testing the marginal influence of other hypothesized variables on international trade. 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). What fundamentals drive world migration? Relative deprivation and social justice. PICH Victor, Les thories migratoires contemporaines au prisme des textes fondateurs. At the same time, cash needs oblige some family members to emigrate to those places where labour markets are associated with a market economy. 5One of the very first explanatory approaches to both internal and international migration focused on individual decision-making. Sjaastad's framework has been extended in a variety of ways . Another important notion in Masseys text is the distinction between the processes that initiate migration and those that maintain it. Wages, rents, and the quality of life. Migration is analysed at the household level and is seen as a form of social insurance. Graves, P. (1983). Southern Economic Journal, 58, 392405. The theory of wages. This global perspective became increasingly fashionable from the 2000s, and generated abundant literature on transnational networks (Schiller et al., 1992; Faist, 2000; Vertovec, 2009). nomic content of the theory of migration proposed by Larry Sjaastad. The 20 texts brought together in the collective work published by INED are identified in the text and the bibliography by an asterisk (*). Brookfield: Ashgate. En fin, las teoras migratorias encuentran su justificacin en la elaboracin y la evaluacin de las polticas migratorias. Journal of Political Economy, 82, 10631093. Most of the texts presented so far focus on legal and voluntary migration. This attention reflects both the importance of the flows and the complexity of the behaviour. Sequential migration theory and evidence from Peru . Are third world emigration forces abating? On migration and risk in LDCs. (1932). 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). Burawoys original contribution is double: he first extended the circulation model to cover all forms of circular migration (international especially), then illustrated his hypothesis via a comparison between Mexico-United States and South Africa. In fact, even if these workers receive market wages (which is not necessarily the case), the maintenance costs linked to socioeconomic integration are kept to a minimum by depriving them of citizenship rights. The long-term consequence of immigration will be the emergence of multicultural societies, leading in turn to new concepts of citizenship and the nation state. The temporary work programmes now re-emerging in industrialized countries also involve a twin economic and institutional dependency. World Bank Policy Research Working Paper 3915. The laws of migration. The first, and the one which has received the major attention, concerns the direction and magnitude of the response of migrants to labor earnings differentials over space. Migration and the option value of waiting. 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). 22The text by Monica Boyd (1989*) is a key contribution to the literature on networks and gender, introducing the idea of networks as links between places of origin and destination that mediate between individual actors (micro) and larger structural forces (macro). Borjas, G. (1991). For Tapinos, examining the economic and political challenges of irregular migration involves identifying what makes this type of migration specific with respect to regular migration. Far from competing, these approaches each provide specific new insights. 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. This prefigures the notion of migration networks that was to become central to migration theory from the 1980s. 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? The social process of international migration. 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. This theoretical model was expanded by Michael Todaro (Todaro, 1969; Harris and Todaro, 1970) and Borjas (1989). (1988). Blanchflower, D., & Oswald, A. the abolition of forced labour), the system of temporary migrant labour continues to exist (Cordell, Gregory and Piche?, 1996). Amenities and rural development theory, methods and public policy. Based on the literature reviews published since 2000, one might be tempted to say yes. This theoretical construct stresses the gender division of labour, which forces women to assume the majority of household tasks and places them in a subordinate position, restricting their geographical mobility in places of origin, or confining them to insecure jobs in places of destination. This new economy has also produced a surge in the supply of low-wage jobs. An econometric study of international trade flows. The Neoclassical Economic Theory, which is mainly used to describe migration between two countries, suggests that there is a correlation between the global supply and demand for labour and the reason people migrate, effectively driven by a wage gap among geographical areas (Sjaastad 1962; Todaro 1969; Jennissen 2007). Beyond measurement problems, debate often focuses on the economic impact of irregular migration. This approach is often associated with the paper by Larry Sjaastad published in 1962*, in which he sought to identify the costs and returns and to determine the rate of return on resources allocated to migration. ), remittances will not significantly accelerate local or national development. An inquiry into the nature and causes of the wealth of nations. (1986). w7487. Journal of Economic Surveys, 3, 277304. Borjas tends to favour the second view. For Tapinos, it is employers who benefit the most. In his view, the idea that immigration reduces the economic well-being of current citizens is not a valid argument for imposing restrictions. Do immigrants really have a negative effect on these opportunities? 24This approach centred on networks and social capital as positive factors has been criticized, by Krissman (2005) among others. American Economic Review, 60, 126142. It is the interplay of these two processes that drives the circular system. Burda, M. (1995). Unfortunately studies of the long term are rare. Mincer, J. Hicks, J. The second point concerns the period covered, namely the decades from the 1960s up to the year 2000. Happiness and economics. New York: Penguin. A simultaneous-Equation approach is applied, which takes account of the interdependence between migration and income and employment changes, and the four-equation model is estimated for 70 labor market areas in Sweden. Journal of Development Economics, 14, 251259. El objetivo del presente artculo es dar cuenta de la evolucin de las teoras migratorias contemporneas a partir de 20 textos fundadores, reagrupados por primera vez en un manual (Pich V., Les thories de la migration, Paris, Ined, 2013). ), Handbook of population and family economics. Oxford: Blackwell. Larry Sjaastad, professor emeritus of economics and a leading expert on trade in Latin America, died May 2. 25As mentioned earlier, the field of migration remains fragmented, with some theories explaining the reasons for migration and others explaining its effects. Borjas, G. (1990). 11Despite the old and outdated vocabulary of Zelinskis article, his contribution is significant on two levels. Here too, there is heated social and political debate between the advocates of pluralism and those who believe that immigration threatens national values. 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). 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. Chicago: University of Chicago Press. 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. In an evolutionist perspective, these societies will develop if they adopt more modern structures and the attitudes that underpin them. Why is this so? He suggests using three major dimensions to define migration: a change in residence, a shift in employment and a shift in social relations. Pich V.. For an exception in the field of fertility and health, see Riley and McCarthy, 2003. Drawing on the theory of labour market segmentation as developed by Michael Piore (1979), the authors describe three modes of incorporation. Regional Science, 18, 131142. Some observers claim that immigrants take the natives jobs, while others argue the opposite, asserting that immigrants have no impact on labour market opportunities for natives. ), Crossing borders: Regional and urban perspectives on international migration. There is a strong presumption that they are not. Sjaastad on migration (1962) "Migration poses two broad and distinct questions for the economist. She examines the reorganization of industrial production, as reflected in the proliferation of sweatshops exploiting undocumented workers, and of industrial homework. The first concerns the emergence of the new paradigm discussed above, namely the globalization of migration flows, which is transforming the role of international migration in todays societies (Kabbanji, 2011). President Saied made his comments this week at a meeting of the . Journal of Economic Literature, 40, 402435. For Borjas, there are two opposing views about how immigration affects the native labour market. Springer, New York, NY. 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). (1776[1937]). This figure represents an analytical framework which sees migration as a multifactorial and multidimensional phenomenon and which incorporates its three main ingredients: origin and destination; micro, meso, macro and global analysis levels; and economic, social and political dimensions (Piche?, 2004). Human migration: Theory, models and empirical studies. As stated above, rather than competing, each approach brings specific new insights that must be taken into account when attempting to explain migration. In G. DeJong & R. Gardner (Eds. We will return to this point later in relation to the founding text by Oberai and Manmohan (1980*). Todaro, M. (1976). (1984). Ruralurban migration in developing countries: A survey of theoretical predictions and empirical findings. Chicago: University of Chicago. There is still a big gap between theory and empirical work, and much needs to be done on the theoretical side of this literature to bridge that gap. 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). A first approach sought to explain migration patterns in terms of a system of multiple flows between origin and destination places: flows of persons, but also of goods, services and ideas. What can economists learn from happiness research? 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. 21Neoclassical theory was strongly criticized by the new economics of labour migration associated primarily with the economist Oded Stark (1991). Greenwich, CN: JAI Press. Most studies of migration determinants investigate the impact of. Costs can be broken down into money and non-money costs. 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? Stark, O., & Levhari, D. (1982). The previous argument has maintained that the unequal process of labour and capital migration if unchecked by offsetting government policies can aggravate rather than reduce the regional problem. Note that Log (11,000)=4.04 while Log (10,000)+(1,000/10,000)=4.1, a difference of only about 1.5%. In: The Economics of Immigration. Here, migration is no longer seen in terms of permanent rupture, and attention focuses rather on the links that are maintained between the home society and the host society, since migrants lives cut across national boundaries and bring two societies into a single social field. The debate arising from Portes work has focused mainly on the positive and negative effects of enclaves in terms of migrant economic integration. American Sociological Review, 11, 677686. Hence, the actors involved in migration networks are not always facilitators; some may also be exploiters. Unfortunately, few other scholars have continued along this path. A life-cycle empirical analysis of migration and climate, by race. Anyone you share the following link with will be able to read this content: Sorry, a shareable link is not currently available for this article. This helps to explain the relative magnitudes of observed gross and net migration. Recent research on the more global economic effects of immigration (at macro level) has produced results that are contradictory and uncertain to say the least (He?ran, 2002). This article aims to explore the development of contemporary migration theories as reflected in some twenty founding texts brought together for the first time in a single volume (Pich V., 2013, Les thories de la migration, INED). But Castles and Kosacks key contribution was to highlight the hierarchical structure of employment, with immigrants often at the bottom of the socioeconomic ladder, leading to a division of the working class. Because native workers and immigrants are not interchangeable in the production process.
