The Effect of Migration on Labor Resources

International migration is a complex phenomenon that can be detected throughout the history of mankind, manifested in varying degrees of intensity, being generated by welfare and development disparities between different regions of the world (EU, 2008). The realities of the last decades, namely the globalization of the world economy, the intensification of the armed conflicts, as well as the economic-regional integration are the main factors that contributed to the quantitative and qualitative remodeling of the international migration. The issue of international migration is not only an economic subject but also a social, cultural and political one, with multiple implications not only on the country of origin but also on the receiving country. Public authorities are not only concerned with the effects of the intensive migration but also with the costs that this phenomenon entails, which affect both the countries of origin and the recipient countries. International events over the last decades have generated not only the phenomenon of voluntary migration caused by job search or economic reasons, but also by forced migration generated by natural phenomena such as political, religious disasters, persecution, or wars. This generates new challenges for public authorities to find solutions to mitigate the negative effects and potentiate the positive effects of international migration.
