Increasingly, immigration policies tend to favor the entry of skilled workers, raising substantial concerns among sending countries. The ‘revisionist’ approach to the analysis of the brain drain holds that such concerns are largely unwarranted.

Finally, the ability to migrate abroad may boost the incentive to acquire skills by home residents.
