Migration and information flows. A new lens for the study of contemporary international migration

Aquest document de treball mira d'establir un nou camp d'investigació a la cruïlla entre els fluxos de migració i d'informació i comunicació. Hi ha diversos factors que fan que valgui la pena adoptar aquesta perspectiva. El punt central és que la migració internacional contemporània és incrustada en la dinàmica de la societat de la informació, seguint models comuns i dinàmiques interconnectades. Per consegüent, s'està començant a identificar els fluxos d'informació com a qüestions clau en les polítiques de migració. A més, hi ha una manca de coneixement empíric en el disseny de xarxes d'informació i l'ús de les tecnologies d'informació i comunicació en contextos migratoris. Aquest document de treball també mira de ser una font d'hipòtesis per a investigacions posteriors.

Migrant Remittances and Information Flows: Evidence from a Field Experiment*

Do information flows matter for remittance behavior? We design and implement a randomized control trial to quantitatively assess the role of communication between migrants and their contacts abroad on the extent and value of remittance flows. In the experiment, a random sample of 1,500 migrants residing in Ireland was offered the possibility of contacting their networks outside the host country for free over a varying number of months. We find a sizable, positive impact of our intervention on the value of migrant remittances sent. Our results exclude that the remittance effect we identify is a simple substitution effect. Instead, our analysis points to this effect being a likely result of improved information via factors such as better migrant control over remittance use, enhanced trust in remittance channels due to experience sharing, or increased remittance recipients’ social pressure on migrants.

Migration and trade: Theory with an Application to the Eastern- Western European Integration

The remarkable increase in trade flows and in migratory flows of highly educated people are two important features of globalization of the last decades. This paper extends a two-country model of inter- and intraindustry trade to a rich environment featuring technological differences, skill differences and the possibility of international labor mobility. The model is used to explain the patterns of trade and migration as countries remove barriers to trade and to labor mobility. We parameterize the model to match the features of the Western and Eastern European members of the EU and analyze first the effects of the trade liberalization which occured between 1989 and 2004, and then the gains and losses from migration which are expected to occur if legal barriers to labor mobility are substantially reduced. The lower barriers to migration would result in significant migration of skilled workers from Eastern European countries. Interestingly, this would not only benefit the migrants and most Western European workers but, via trade, it would also benefit the workers remaining in Eastern Europe. Key Words: Skilled Migration, Gains from Variety, Real Wages, Eastern-Western Europe. JEL Codes: F12, F22, J61.

A global view of cross-border migration

This paper evaluates the global welfare impact of observed levels of migration using a quantitativemulti-sector model of the world economy calibrated to aggregate and firm-level data.Our framework features cross-country labor productivity differences, international trade, remittances,and a heterogeneous workforce. We compare welfare under the observed levels ofmigration to a no-migration counterfactual. In the long run, natives in countries that receiveda lot of migration -such as Canada or Australia- are better o due to greater product varietyavailable in consumption and as intermediate inputs. In the short run the impact of migrationon average welfare in these countries is close to zero, while the skilled and unskilled nativestend to experience welfare changes of opposite signs. The remaining natives in countries withlarge emigration flows -such as Jamaica or El Salvador- are also better off due to migration,but for a different reason: remittances. The welfare impact of observed levels of migration issubstantial, at about 5 to 10% for the main receiving countries and about 10% in countries withlarge incoming remittances. Our results are robust to accounting for imperfect transferabilityof skills, selection into migration, and imperfect substitution between natives and immigrants.

L'évolution de la migration interrégionale au Québec (1991-2006)

Ce mémoire présente, dans une première partie, une analyse détaillée des flux migratoires entre les différentes régions administratives du Québec entre 1991 et 2006. Nous avons utilisé quelques indicateurs permettant de quantifier l’importance de ces mouvements à la fois sur la région d’origine et sur la population d’accueil. Afin de réaliser ce travail, nous avons eu recours aux matrices de flux migratoires entre les 17 régions administratives québécoises, matrices qui sont publiées par l’Institut de la Statistique du Québec à l’aide du fichier de la Régie de l’assurance-maladie du Québec (RAMQ). Les méthodes d’analyse utilisées nous ont permis de mesurer l’intensité de ces flux, leur concentration spatiale, l’orientation spatiale des émigrants, les hiérarchies des régions administratives ainsi que l’efficience des migrations interrégionales du Québec. Nous avons analysé comment les régions administratives du Québec sont affectées par la migration interrégionale. Dans une deuxième partie, nous avons porté notre attention sur la migration interrégionale en fonction de certains groupes d’âge. L’étude des migrations en fonction du groupe d’âge a permis de mieux saisir les conséquences démographiques de ces mouvements pour les régions d’origine et de destination, particulièrement en ce qui concerne la structure de la population résultant de ces flux. Finalement, dans une troisième partie, nous avons analysé les mouvements migratoires entre l’île de Montréal et les Municipalités Régionales de Comté des quatre régions qui l’entourent afin de comprendre la part de l’étalement urbain dans l’émigration des Montréalais. Les résultats obtenus nous permettent de conclure en dégageant certaines tendances. D’abord, nous avons établi que les migrations dans la province de Québec se font des régions éloignées vers les régions du centre. Ces régions gagnantes renferment ou avoisinent les grands centres urbains de la province : Québec, Montréal et Ottawa. Nous assistons donc à une redéfinition du paysage québécois : le nord se déserte, le centre a une faible croissance et la grande région de Montréal, plus particulièrement les régions en banlieue de l’île de Montréal, est en nette croissance. Ensuite, l’analyse par groupe d’âge a illustré que les régions excentrées ont très rarement des soldes positifs et que les jeunes sont très nombreux à quitter ces régions. Pour l’île de Montréal, ce sont les jeunes qui arrivent en grand nombre. Cependant, après la trentaine, les gens désertent l’île pour d’autres régions de la province. Ces départs profitent aux régions adjacentes, qui font d’énormes gains chez les jeunes travailleurs. Finalement, l’analyse des échanges migratoires entre l’île de Montréal et les MRC des quatre régions adjacentes nous a permis de constater que ces MRC sont très souvent gagnantes dans leurs échanges migratoires. Particulièrement lors de la période 2001-2006, où seulement deux territoires sont perdants dans leurs échanges migratoires avec les autres régions du système, soit l’île de Montréal et la MRC de Longueuil.

The effect of environmental change on human migration

The influence of the environment and environmental change is largely unrepresented in standard theories of migration, whilst recent debates on climate change and migration focus almost entirely on displacement and perceive migration to be a problem. Drawing on an increasing evidence base that has assessed elements of the influence of the environment on migration, this paper presents a new framework for understanding the effect of environmental change on migration. The framework identifies five families of drivers which affect migration decisions: economic, political, social, demographic and environmental drivers. The environment drives migration through mechanisms characterised as the availability and reliability of ecosystem services and exposure to hazard. Individual migration decisions and flows are affected by these drivers operating in combination, and the effect of the environment is therefore highly dependent on economic, political, social and demographic context. Environmental change has the potential to affect directly the hazardousness of place. Environmental change also affects migration indirectly, in particular through economic drivers, by changing livelihoods for example, and political drivers, through affecting conflicts over resources, for example. The proposed framework, applicable to both international and internal migration, emphasises the role of human agency in migration decisions, in particular the linked role of family and household characteristics on the one hand, and barriers and facilitators to movement on the other in translating drivers into actions. The framework can be used to guide new research, assist with the evaluation of policy options, and provide a context for the development of scenarios representing a range of plausible migration futures.

The persistence of distance: a gravity model of European cross-border real estate development flows

Purpose – This paper aims to investigate the scale and drivers of cross-border real estate development in Western Europe and Central and Eastern Europe. Design/methodology/approach – Placing cross-border real estate development within the framework of foreign direct investment (FDI), conceptual complexities in characterizing the notional real estate developer are emphasized. Drawing upon a transaction database, this paper proxies cross-border real estate development flows with asset sales by developers. Findings – Much higher levels of market penetration by international real estate developers are found in the less mature markets of Central and Eastern Europe. Analysis suggests a complex range of determinants with physical distance remaining a consistent barrier to cross-border development flows. Originality/value – This analysis adds significant value in terms of understanding cross-border real estate development flows. In this study, a detailed examination of the issues based on a rigorous empirical analysis through gravity modelling is offered. The gravity framework is one of the most confirmed empirical regularities in international economics and commonly applied to trade, FDI, migration, foreign portfolio investment inter alia. This paper assesses the extent to which it provides useful insights into the pattern of cross-border real estate development flows.

Focus on environmental risks and migration: causes and consequences

Environmental change poses risks to societies, including disrupting social and economic systems such as migration. At the same time, migration is an effective adaptation to environmental and other risks. We review novel science on interactions between migration, environmental risks and climate change. We highlight emergent findings, including how dominant flows of rural to urban migration mean that populations are exposed to new risks within destination areas and the requirement for urban sustainability. We highlight the issue of lack of mobility as a major issue limiting the effectiveness of migration as an adaptation strategy and leading to potentially trapped populations. The paper presents scenarios of future migration that show both displacement and trapped populations over the incoming decades. Papers in the special issue bring new insights from demography, human geography, political science and environmental science to this emerging field.

Pakistani Migration to the United States:An Economic Perspective

The 9-11 attack on the US brought a set of changes in overseas migration from Pakistan. One such change is the sharp increase in remittances sent from the United States. The paper argues that the characteristics of remittances from the United States differ from those originating in the Middle East. Just as the overseas Pakistani communities are diversified, the nature and characteristics of remittances are heterogeneous, depending on where they come from and who sends them. While the importance of remittance flows from the United States is rising, not much academic attention has been paid to this issue because of a lack of data. To better understand the reasons behind the increase in US remittances, and in order to evaluate their sustainability, household surveys are necessary.

Enhanced radon emission in natural CO2 flows in Campo de Calatrava region (central Spain)

Activity of radon gas in natural soils is commonly low (in the order of few thousands of Bq·m-3) due to the fast decay (half-life= 3.8 days in the case of 222Rn) that prevents accumulation in soil pores. Exceptionally, high Rn soil activity (up to 430 KBq·m-3) is found around point sources of deep CO2 fluxes. These fluxes allow the transport of trace gases (including Rn) to long distances in the geosphere leading to a potential hazard as Rn accumulation in buildings. CO2 degassing is common in active or ancient volcanic fields and occurs as free gas fluxes or dissolved in groundwater. In this work, the occurrence of Rnbearing, CO2 fluxes from the Campo de Calatrava region in Central Spain has been studied in order to determine their (1) magnitude, (2) migration paths and (3) potential impact on the environment, and (4) methodologies to best detection and measurement.

Linking tourism, retirement migration and social capital

A general trend in the study of international retirement migration has been the increased attention paid to the social contacts and network connections of the migrants in both the destination and the origin areas. These studies have examined the extent to which migrants build social relationships with their neighbours and the host society while also maintaining social links with their countries of origin, addressing the central role that leisure travel plays in sustaining increasingly dispersed social networks and maintaining the social capital of these networks and of the individuals involved in them. Using a case study approach to examine British retirement migration to Spain, we explore the relevance of transnational social networks in the context of international retirement migration, particularly the intensity of bidirectional visiting friends and relatives (VFR) tourism flows and the migrants’ social contacts with friends and/or family back in their home country. Building on the concept of social capital and Putnam's distinction between bonding and bridging social capital, we propose a framework for the analysis of the migrants’ international social networks. The results of a study conducted based on a sample of 365 British retirees living in the coast of Alicante (Spain) show both the strength of the retirees’ international bonding social capital and the role of ‘VFR's travel and communication technologies in sustaining the migrants’ transnational social practices and, ultimately, their international bonding social capital. It also provides evidence for the reinforcing links between tourism-related mobility and amenity-seeking migration in later life.
