Migration in Eastern Europe and Central Asia is relatively large by international standards, driven both by political factors --the 1990 collapse of the Soviet system, ensuing emergence of conflicts and new states, and opening of borders with Europe--and economic factors--abrupt economic deterioration and corresponding search for better employment and living conditions. The report analyzes the different kinds of migration as well as the policies on both sides of the equation to limit negative side effects--like emargination, criminal activities, and brain drain--and maximize positive ones--remittances, return migration with improved human and financial capital.
