Theoretical Foundations Of International Migration

In present-day dynamically changing conditions of the global socio-economic environment, thecomprehension and regulation of cross-border mobility of labour pose the need for systematic familiarity with and study of the theory of international migration. The present study contains a descriptive andcritical analysis of the major classical and alternative theoretical concepts of international migration.On that basis, along with the used empirical data, both internationally and nationally, in some cases the arguments on which migration theory is based are accepted, in others -they are rejected.There is traced the reality in Bulgaria during the past two decades, after the changes,in the context of the theoretical framework under study. It is found that in the different periods certain factors are more powerful than others. Of crucial importance are the very nature, specific forms and functions of migration. The ambiguous interpretation of cross-border mobility necessitates a deeper theoretical study of international migratory processes, as well as a closer binding between theory and empiricism for the purposes of the modern migratory analysis.
