International economic migration in OECD countries - Discovering economic costs and benefits, and finding recent migration trends

The main objective of this study was to find studies regarding both the economic effects of immigration and emigration. Additionally, the study had an objective to search for patterns of international migration in the OECD countries to find out where migration peaks have taken place in the last few decades. It is important to examine international migration, since flows of migrants have accelerated due to globalization and a growing world population, for example. This paper draws conclusions based on secondary sources and calculations that use public data figures. There is a gap in source availability between immigration and emigration, which makes it more difficult to study the economic effects of emigration, compared to examining the effects of immigration. Migration trend wise, the US has had active inbound, and Germany outbound flows of migrants in the 21st century. It appears that straightforward, general conclusions are not possible to make in most economic aspects, since there are many variables that affect the economic results of migration. Certain demographics of migrants, like the age and skill level, are important factors that define the economic effects of migration. Also, public structures of host countries affect the behavior and assimilation of immigrants
