Interrelations between Public Policies, Migration and Development is the result of a project carried out by the European Union and the OECD Development Centre in ten partner countries: Armenia, Burkina Faso, Cambodia, Costa Rica, Côte d'Ivoire, the Dominican Republic, Georgia, Haiti, Morocco and the Philippines. The project aimed to provide policy makers with evidence on the way migration influences specific sectors - labour market, agriculture, education, investment and financial services, and social protection and health - and, in turn, how sectoral policies affect migration. The report addresses four dimensions of the migration cycle: emigration, remittances, return and immigration. The results of the empirical work confirm that migration contributes to the development of countries of origin and destination. However, the potential of migration is not yet fully exploited by the ten partner countries. One explanation is that policy makers do not sufficiently take migration into account in their respective policy areas. To enhance the contribution of migration to development, home and host countries therefore need to adopt a more coherent policy agenda to better integrate migration into development strategies, improve co-ordination mechanisms and strengthen international co-operation.
