Two prominent features of international labor movements are that the more educated are more likely to emigrate (positive selection) and more educated migrants are more likely to settle in destination ...countries with high rewards to skill (positive sorting). Using data on emigrant stocks by schooling level and source country in OECD destinations, we find that a simple model of income maximization can account for both phenomena. Results on selection show that migrants for a source-destination pair are more educated relative to non-migrants the larger is the absolute skill-related difference in earnings between the destination country and the source. Results on sorting indicate that the relative stock of more educated migrants in a destination is increasing in the absolute earnings difference between high and low-skilled workers. We use our framework to compare alternative specifications of international migration, estimate the magnitude of migration costs by source-destination pair, and assess the contribution of wage differences to how migrants sort themselves across destination countries.

Migration flows are shaped by a complex combination of self-selection and out-selection mechanisms, both of which are affected by the presence of a diaspora abroad. In this paper, we analyze how ...existing diasporas (the stock of people born in a country and living in another one) affect the size and human-capital structure of current bilateral migration flows. Our analysis exploits a bilateral data set on international migration by educational attainment from 195 countries to 30 OECD countries in 1990 and 2000. Based on simple micro-foundations and controlling for various determinants of migration, we found that diasporas increase migration flows and lower their average educational level. Interestingly, diasporas explain majority of the variability of migration flows and selection. This suggests that, without changing the generosity of family reunion programs, education-based selection rules are likely to have moderate impact. Our results are highly robust to the econometric techniques, accounting for the large proportion of zeros and endogeneity problems.
This paper synthesizes insights from new global data on the effeaiveness of migration policies. It investigates the complex links between migration policies and migration trends to disentangle policy ...effects from structural migration determinants. The analysis challenges two central assumptions underpinning the popular idea that migration restrictions have failed to curb migration. First, post-WWII global migration levels have not accelerated, but remained relatively stable while most shifts in migration patterns have been directional. Second, post-WWII migration policies have generally liberalized despite political rhetoric suggesting the contrary. While migration policies are generally effective, "substitution effects" can limit their effeaiveness, or even make them counterproduaive, by geographically diverting migration, interrupting circulation, encouraging unauthorized migration, or prompting "now or never" migration surges. These effeas expose fundamental policy dilemmas and highlight the importance of understanding the economic, social, and political trends that shape migration in sometimes counterintuitive, but powerful, ways that largely lie beyond the reach of migration policies.
While there is considerable interest in understanding the climate–migration relationship, particularly in the context of concerns about global climatic change, little is known about its underlying ...mechanisms. In the paper, we combine a rich panel data on annual bilateral international migration flows with an extensive data on climate variability across the countries to investigate in-depth the climate–migration link. We find a positive and statistically significant relationship between temperature and international outmigration only in the most agriculture-dependent countries, consistent with the widely documented adverse impact of temperature on agricultural productivity. Further, the temperature–migration relationship is nonlinear and resembles the nonlinear temperature–yield relationship. In addition, migration flows to current major destinations are especially temperature-sensitive. Policies to address issues related to climate-induced international migration would be more efficient if focused on the agriculture-dependent countries and especially people in those countries whose livelihoods depend on agriculture.
•We examine the relationship between climate variability and international migration.•We use an annual bilateral international migration data set for 1980–2010.•Temperature induces international outmigration only from agricultural countries.•Migration flows to current major destinations are especially temperature-sensitive.
This article examines the importance of language in international migration from multiple angles by studying the role of linguistic proximity, widely spoken languages, linguistic enclaves and ...language-based immigration policy requirements. To this aim we collect a unique data set on immigration flows and stocks in 30 OECD destinations from all world countries over the period 1980–2010 and construct a set of linguistic proximity measures. Migration rates increase with linguistic proximity and with English at destination. Softer linguistic requirements for naturalisation and larger linguistic communities at destination encourage more migrants to move. Linguistic proximity matters less when local linguistic networks are larger.
Using Danish linked employer–employee data, this study examines the importance of access to higher-paying firms in the wage assimilation process among immigrants during their 25-year tenure in ...Denmark. Upon their arrival, immigrant workers in Denmark earn substantially lower wages than their native counterparts. However, this wage gap diminishes rapidly within the first 5–10 years, particularly among more disadvantaged immigrant groups (non-OECD and female immigrants). Immigrants who enter the labour market early have higher earnings capacity than those who enter later, but this trend reverses after 15 years. The transition to higher-paying firms constitutes a crucial factor in wage assimilation during the initial 5 years, yet it does not account for wage growth beyond this period. Additionally, this study offers suggestive evidence that Danish firms’ wage policies vary based on the duration since migration, and these differences significantly contribute to the wage assimilation process.
•Immigrants in Denmark initially face a wage gap that drops sharply within 10 years.•The wage gap reduction is most pronounced among non-OECD and female immigrants.•Immigrants entering the labour market early show higher earning capacity.•Access to high-paying firms is key in immigrants’ first 5 years of wage assimilation.•Firms’ wage policies vary by migrants’ stay length and impact assimilation.

International migration data in Europe are collected by individual countries with separate collection systems and designs. As a result, reported data are inconsistent in availability, definition, and ...quality. In this article, we propose a Bayesian model to overcome the limitations of the various data sources. The focus is on estimating recent international migration flows among 31 countries in the European Union and European Free Trade Association from 2002 to 2008, using data collated by Eurostat. We also incorporate covariate information and information provided by experts on the effects of undercount, measurement, and accuracy of data collection systems. The methodology is integrated and produces a synthetic database with measures of uncertainty for international migration flows and other model parameters. Supplementary materials for this article are available online.
The use of bilateral data for the analysis of international migration is at the same time a blessing and a curse. It is a blessing because the dyadic dimension of the data allows researchers to ...address a number of previously unanswered questions, but it is also a curse for the various analytical challenges it gives rise to. This paper presents the theoretical foundations of the estimation of gravity models of international migration, and the main difficulties that have to be tackled in the econometric analysis, such as the nature of migration data, how to account for multilateral resistance to migration or endogeneity. We also review some empirical evidence that has considered these issues.
•We examine the role of social networks in explaining the intention to migrate.•A single framework is used for the local and international migration intentions.•Social networks abroad explain the ...largest share of variation in migration intention.•Close social networks at home reduce the probability of intention to out-migrate.•Close networks with remittances are more important than those without remittances.
Using a large individual-level survey spanning several years and more than 150 countries, we examine the importance of social networks in influencing individuals’ intention to migrate internationally and locally. We distinguish close social networks (composed of friends and family) abroad and at the current location, and broad social networks (composed of same-country residents with intention to migrate, either internationally or locally). We find that social networks abroad are the most important driving forces of international migration intentions, with close and broad networks jointly explaining about 37% of variation in the probability intentions. Social networks are found to be more important factors driving migration intentions than work-related aspects or wealth (wealth accounts for less than 3% of the variation). In addition, we find that having stronger close social networks at home has the opposite effect by reducing the likelihood of migration intentions, both internationally and locally.
The diffusion of tacit knowledge involves direct human interactions. This implies that the international diffusion of knowledge should follow the pattern of international migration. We test this idea ...using cross-country productivity spillovers leading to new exports as proxy for knowledge diffusion. We find that a 10% increase in immigration from exporters of a given product is associated with a 2% increase in the likelihood that the host country starts exporting that good 'from scratch' in the next decade. The results appear stronger for highly-skilled migrants, qualitatively similar for emigrants and robust to instrumenting for migration in a gravity framework.
