ABSTRACT
The patterns of migration processes are complex. A first, to some extent simple explanation for this complex picture is that countries use different methods of collecting data on migration flows. A further increase in the complexity of migration processes stems from the fact that the composition of migrants is subject to considerable change over time. In the globalized economy, high-skilled migration has intensified competition among countries to attract the best talents. Recent trends in international migration confirm that in developed countries more and more migrants arrive with tertiary education. International students and migrant entrepreneurs have become of outmost importance as a source of high-skilled migrants. The statistics of international students worldwide shows a strong increase for the last three decades. Moreover, migrant entrepreneurs employ on average at least 2.4 per cent of the total employed population in OECD countries. A considerable number of high-skilled individuals also arrive as envoys of multinational companies.
