The Factors that Make and Unmake Migration Policies1

Migration policies often fail to achieve their declared objectives or have unintended consequences. This article discusses three sets of reasons for this: factors arising from the social dynamics of the migratory process; factors linked to globalization and transnationalism; and factors within political systems. Effective policies are often hampered by the one‐sided explanatory models used to explain migration, as well as by interest conflicts in both domestic and international politics. In many cases this leads to migration policies with contradictory objectives or hidden agendas. The article goes on to discuss some elements of a conceptual framework for improving policy formation and possible components of fairer and more effective migration policies at the national, regional and global levels.
