– Lessons for Policy
The most important economic feature of immigration to the United States in the post-1965 period has been a significant deterioration in the economic performance of successive immigrant waves.

Increasingly, immigration policies tend to favour 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. First, sustained migratory flows may be associated...

We examine the ways in which candidate countries which are to join the EU in 2004 are responding to increasing asylum migration from the East and assess the impact of accession on their asylum and immigration laws and policies. It will be argued that recent changes in asylum and immigration laws in...

The European Union approach is different: provide aid first, and later free...
